HVACR VIDEOS How long were you at that location working on the unit? I’m not being critical. Trying to convince co-workers that sometimes things take a while to make long term repairs.
nota newbie I get to the point of thinking that if no one serviced the cheapo operators any more they eventually would have to pay, I was recently turfed on a job because I quoted a new evap and lineset on a bad leaker, sure enough they had the gas and go guys there the next day... what’s needed is the EPA to start fining these restaurant and store owners if they don’t want to pay to have their junk repaired / replaced, not just the technicians and service companies. Refrigeration is expensive.
@hvacr tech I love the comment "fired the customer" I am curious if these customers end up spending more in the long run ..(ie Spend 100 dollars now or spend 1000 dollars later ??)
I'm willing to bet that the reason they have all those droplets on the ceiling is because someone is bringing hot food and cooling in the freezer seen it a million times when I was a cook.
@@megabadass30 A freezer 3 wire fan work when the coil hits 10 deg. It turns on the fans. the brown wire is the (x) on timer kick it out of defrost at 50 deg. So it fans turn on with no delay the is wrong. You kill the compressor. Freezer is not a cooler does not work the same. . I seen ice in the pan this is a bad drain system. Allway have a gup like a 1/18 copper ele over the drain outlet. Not rigid to pan. This pan is removable. Never hard pipe it to outlet. Moisture is sweat from Heat in defrost.
Fan delay after defrost!!!! Allow the water to drain away first after defrost then any water in the tray does not spray onto the ceiling and freeze causing the droplets on the ceiling.
The annoying thing with fridges/freezers is that people don't know how they work. They think "oh there's ice on the evaporator coil so that means its working", but they don't realize we need airflow to remove heat. I have an older lady who runs a pub and she assures me that she should be running her coolroom at -1 because "thats how she's always done it". I'm back removing ice every two months because it only has a fan controlled defrost since its a chiller and not a freezer. Every single time i get an earful, so one day i sat her down and explained the ins and outs of what happens in a refrigeration system. You'll be happy to know the next time i went there the thermostat was set at -1 again and i got another earful :)
My boss would reply, "that's fine, we will gladly take their money". I had a customer that repeatedly stabbed his evap coils when they iced up. Kept fixing leaks from the stabs. We gladly took his money.
lol thats a good one. I had a restaurant supply supper center that was running a island cooler at 29F. And every month or so we would go in and have to spray down the coils to de-ice them. I tried contacting their controls company which was out of state. All the temps in the store were controlled from out of state. I finally spoke to someone there and asked them how many defrost cycles did the island cooler have. None... of course was the answer. So I told them...that case was not designed to keep ice cream cakes or to run at that temp. It was causing constant flood-back to the rack. To this day. It's running the same at a cost of valve plate and compressor replacements.
I once diagnosed my parents ac unit when I was 14. I typed up Ac not working on youtube and found out that capacitors go bad. When I opened up the back housing of the unit, there it was, a buldge sticking out the top of the capacitor.

When I was a kid there was a programme on Southern Television (UK) called out of town where a chap called Jack Hargreaves would show how people used to do the jobs in the country - this is like the modern version - its really interesting to see what you do and how you think through the problem - thank you so much.
Having worked at a job where I need to go into a walk in freezer I have to say the end result please me greatly. It is so awesome to be able to just walk in and grab something without having to dig through several layers or permafrost.
I have learned a lot more by watching your videos about troubleshooting the units then from watching and listening to a top notch service guys in my company!!! Love it
I stumbled upon your channel and its amazing how knowledge you have. I'm just starting my HVACR training and certification. You videos are very educational to a newbie like myself. Keep up the great work all the best for you
Im in HVAC/R school and I love all the free bits of info I can get! Especially info from folks who seem like they know what they’re talking about. Thank You!
good thing this is a restaurant and not a food manufacturing plant, they'd be getting cited under 21 CFR 117.35(a) for all that condensation all over everything. condensation is considered insanitary.
That's why there's frozen water droplets all on the ceiling and spread through out the box. If you have a fan-delay switch that is not working. It will spray out water droplets every where since the fans just come on right when the t-stat calls. Water droplets all over the ceiling is an indicator that you have an issue with defrost, draining, or fan-delay. Great vid.
i fix garage doors, I've had a customer drive completely through the door, and blamed it on me because "the garage didnt open fast enough." they were the ones that put in the opener, because I was "too expensive" tf is up with people like that.

I work in a major retailer that has numerous walk in coolers / freezers, as well as whole isles for display, I have seen a lot over my years, one of the best was maintenance arguing that we were leaving door open, seals were a little worn, he replaced, kept on, still freezing up, finally he started listening, door never left open other than when loading or unloading, turned out drain for evap pan had broke & there was no trap working, most have a water trap to not allow air back, well that was allowing warm air into it, after he fixed line, no issues in several years.
Just wanted to say. I really enjoy your videos. As a fellow Hot side/Commercial refrigeration tech. Your videos are the most informative and thorough I’ve come across. Keep it up brother. Would love to pick your brain and shoot the S sometime.
I like how, instead of telling them "Everything is moisture ruined due to you guys leaving the door open", you just install a solution that will make it impossible for them to forget to close the door :) I am sure after they jump out of their skin a couple times from the alarm, they will stop doing that.
This was very educational, I used to work for mcdonalds as a maintenance man and my god did I wish you worked on our freezer. I swear they refused to get a proper job done because you literally pointed out at least four things that I am pretty certain were the issues with their system but they wouldn't listen or pay the money to get it done right.
Looks exactly like the freezer where I work. My walk in has two piles of ice about 3 inches thick and a good 2 metres wide... One night when our freezer happened to be empty I took a hammer to the ice and removed it all. The managers were happy but some months later the ice had come back. Management didn't give two shits about the leak in the freezer.
Very informative... thank you for your effort and patience to make the videos. I’m just getting into the refrigeration and for this old technician to learn new methods and techniques is very helpful when people like you make videos like these. Keep up the great work...!!
Refrigeration is hard to learn in my area. Just cause nobody does it correctly. Watching your videos makes me more confident as a tech. Thanks! I subscribed!
Always should pass through a cooler to enter a freezer. Warm, moist air is our #1 enemy in freezers. That defective fan-delay allows the warm, moist defrost-air to add frost onto the product-boxes, walls, ceiling, etc. Luv the new Ranco thermostat and the Alarm. GR8 video ! 🎉
Great job all the around... You make us over protective commercial refrigeration techs look good and worth this Bill I give after recommending they watch your video until we have time to make some
I'm a Hvac Tech with 9 years, Residential HVAC experience. With no commercial Refrigeration experience, brother ur videos are freaking amazing. I want to learn more about commercial Refrigeration, its my passion my ❤. Great video good, very good professional work i saulte u and respect ur work as a Hvac Tech
Great job..way to show a great example of a good tech. However it was a good account that you could do all the work. So many times people want it done on the cheap. Always. I see it everyday
Interesting as a fellow refrigeration technician that this video was recommended for me. I'm just sitting here watching and diagnosing along with you. Keep up the working. ^,..,^

Nice work! Good to see there is good service techs out there still. Many of them wouldn't have done half the things you did and just skated outta there.
Thanks for the nice words, I started making these videos to show my own service techs how I want them to perform their service calls. Than i decided to make them public because there is massive amount of people that do not look at the big picture.
i worked in a kitchen before that had the same exact problem, frost everywhere and especially around the door. The evaporator was directly in the middle of the ceiling and facing downward. Sometimes it would get so bad that the whole fan blades would be frozen and not spinning. Sometimes it would melt and drip to the floor where it would form a giant ice mountain (very safe). They said that the HVAC techs couldn't figure it out, but after working there for so long I figured they got a quote and said "screw that" especially since their station fridges constantly need to be refilled with refrigerant
One video showed up.... i had a curiosity... been binge watching since, even subbed to the channel. Now, I am ready for a waivered, ride along. (Hate missing some of the work that ends up on the editing floor.) Awsome job.👍

Great job,a professional ethical service tech.well done.i didn’t notice if you checked the door heater?also from experience almost all employees keep the freezer door cracked open because they fear getting locked inside
Same issue im getting for some of my coldroom hear in Qatar and its allot of humid here during summer,anyway good job its like a newly install coldroom the client will appreciate what you did.
Nice job Gaskets sometimes can be a pain like door heaters Just had a walk in cooler act up only when it very cold outside Ended up being a intermittent problem with low pressure control STICKING ONLY DURING FREEZING WEATHER OUTSIDE RESPECT ON YOUR VIDEOS👍🏻 as refrigeration is always fun 😳
Me too. But I was looking at ground heat pumps excessively day before so it make sense. I would watch it anyway, very cool. Another great channel of just doing things In the field: Andrew Camarata, excavations and other soil/ground/drainage related stuff by one man. Addictive.
This is How a Service Call With this issue SHOULD be Done ! Well done Chris & company! ( FTNGOT) unfortunately , 90% of customers will NOT Approve the cost to do this repair. ( Ftngot) - whenever i see frozen water droplets blown all across the ceiling guys u are looking at one of 2 things. most likely someone found a defective (DFTS) defrost termination switch/combination fan delay switch, did not have one on the truck and bypassed the DFTS or its just plain defective, replace it, so, what is going on is after the defrost cycle terminates the Drain pan still has water in it and the fans are coming on right after defrost Blowing any water on the coil or in the pan across the room. the box pulls down and freezes all that blown around water all over the room. u also want to make sure the drain line is clean and clear and drain line heater is fully functional. 90 percent of the time installing a New Fan delay switch / Defrost termination switch will solve this issue, but u also need to make sure All the water is leaving the drain pan within a few minutes. for customers that cannot or do not desire to drop all the cash at one time u could spread out this repair over time. replace the DFTS and check drain line first, in 3 months do a door closer, in 3 months do a door gasket. this spaces repairs over time for smaller customers and Keeps u coming back and can touch base with customers / good customer relations. FTngot = short for - For the new guys out there. Torn door gaskets are a Health department violation in california and a citable violation in california, so customers have to replace door gaskets unless they want thier business shut down- so those are a pretty easy sell and they stop doors from closing properly and cause all kinds of other problems units running all the time because the door is not closed , units shut off and come back on again too quickly stressing compressors short cycling, causing frozen evaporators on refrigerators etc, etc. good door seals are a must. Door closer on this service call was also a standout- it definately needed replaced also.
Thanks for watching Phil, and thanks for adding your 10 cents. Those are some great points you made!! Guys that are reading these comments listen to Phil and sub to his channel he has great content!
Exactly...I’m having the same issue at a hospital that we do PM’s at. The building engineers swear that’s not the problem because they say the defrost termination switch works just fine and it’s defrosting. They don’t understand what the fan delay is there for. Those coils are supposed to get cold enough to freeze any residual water left on the coils after defrosting so that they don’t spray water all over the place when the fan kicks on. It’s hard to convince a building engineer that doesn’t know shit about how their unit is supposed to operate.

It's nice to watch other craftsmen work. Something else which wasn't mentioned in the recap is that since the drip tray was misaligned and frozen up, it wasn't able to remove moisture from the freezer. Since the freezer is a sealed environment most of the time, the only way for moisture to escape is through condensate dripping off the exaporator and out through the drain during the defrost cycles. I would imagine that the moisture instrusion problem in the electrical boxes will be much reduced just by re-enabling the moisture egress path, but a surface mount replacement was certainly a very good idea!
Door seal is usually #1 problem with moisture and icing. Glad you found the other problems, like you said the job is 1 1/2 hours away from your base. The flat roof with standing water was a concern as well if a leak develops.
Love the troubleshooting and general diagnostics. Craftsman, regardless of specialty, have a way about them. I do all kinds of DIY and recently had a residential 40+ year old GE refrigerator burp. Needless to say, over the last few days, I've been OD'ing on refrigeration theory, practice, engineering, and repair. Thanks for putting in the effort to take us along on your professional endeavors! Highly interesting stuff for those of us with a mechanical bent. Oh, and my 40+ year old GE refrigerator? It lives on to cool another day!
Good thing cutomer paid and happy. Its very sad that here is south Ontario some customer dont want to spend money on their equipments but expect keep running . Eventually end up replacing their equipments. But Its hard to convince some of them . Good video. Thanks.
Another job well done fella. I especially liked the idea of trimming the seal to make it install. I would of still been there today trying to stuff that thing lol with a screwdriver.
Great video!! Love the fact that you examine everything before moving on to another job. I work at a fast moving company and they hate the fact that I take my time with services. Lol my response is how many call backs do I get? They reply hardly non. I say exactly. Lol
Great video. I'm going to keep in mind that controller cuz I work at a school district and I've been there for nine years and occasionally I have to take care of some low temperature problems. We have some walk-in coolers in a few freezers. I've been mostly HVAC my 35 year career. I use electronic controllers on the district's walk-in coolers because we need tighter temperature controls. The dixell alarm kit that you installed is something that I'm probably going to be using a lot more here cuz we have the same problems with the monitors. Silicone never does the job I always use foam fill and have a lot better success. I occasionally replace some of our equipment. I always use foam I never use silicone it never feels every little crack and you have to fill every single crack. That dixell controller that you put on there will be really good at the school district here for some of our problem boxes. Great video

Great video and very thorough job. One suggestion: After too many times dragging a hose into a box I got a 50' pieces of 1/4" ice maker tubing. Added various adaptors to fit different water hookup scenarios and a shutoff at the end. It's lighter in weight, easier to pull off the truck, provides gentle spray on coils, takes up much less room and saves a lot of TIME with setup and tear down. Just a thought. Keep up the good work.
I used a 2 gallon pump up sprayer that I extended the hose on with a quick disconnect at the tank. Sometimes getting a hose where you need it wasn't worth the hassle.
Customer complaint: Their freezer is frosty inside. Um... Lol! Sorry, that hit me funny. It is nice to see that there are still people who know how things work such that they can properly diagnose and repair them. Nice work.
Great video . I’m dealing with the same kind of problem with a faulty or disconnected limit switch and severe ice build up in the coil. I’m going back tomorrow to follow up and finish the call.
3 wire fan delay. Yup. A cheap part to replace regardless. If you have the coil sides cleaned and exposed, replace the 3wire fan delay. It's a snap disc, it's been exposed to heat/cold and snapping away. Definitely inspect the part and connections. It would be a shame to get a call back because of the F.D failing after you were just there. Best wishes!! Thank you for sharing!!👍😎😎
Exactly what happens at our work. They leave the freezer door open all the time. I told them they need to keep that freezer door closed We have replaced four gaskets so far it is usually because the company who delivers of food keeps both doors open so they can bring them into the cooler are freezer
I usually find the hinge springs need to be replaced or adjusted on those type of hinges. You can get just the spring cartridges for not too much. Great job catching the limit switch.

Always should pass through a cooler to enter a freezer. Warm, moist air is our #1 enemy in freezers. That defective fan-delay allows the warm, moist defrost-air to add frost onto the product-boxes, walls, ceiling, etc. Luv the new Ranco thermostat and the Alarm. GR8 video ! 🎉
We done an exhaustive inspection and detailed assessment, Very informative. Congratulation!
Great job all the around... You make us over protective commercial refrigeration techs look good and worth this Bill I give after recommending they watch your video until we have time to make some
Thank you for the heads up on the moisture intrusion in the walls. Good one to take in account.

I'm a Hvac Tech with 9 years, Residential HVAC experience. With no commercial Refrigeration experience, brother ur videos are freaking amazing. I want to learn more about commercial Refrigeration, its my passion my ❤. Great video good, very good professional work i saulte u and respect ur work as a Hvac Tech
Thanks bud
Great job..way to show a great example of a good tech. However it was a good account that you could do all the work. So many times people want it done on the cheap. Always. I see it everyday
Your channel is the best one on here. Thank you for what you do
I installed that read out/alarm kit today on a school's WIC . I was impressed with it.
Interesting as a fellow refrigeration technician that this video was recommended for me. I'm just sitting here watching and diagnosing along with you. Keep up the working. ^,..,^
why did i not find these videos 6 months ago wouldve saved so much time and amazing info thank you
thanks for watching! I will be going live on TH-cam this evening 2/17/20 @ 5:PM (pacific time) to discuss past videos and answer questions from TH-cam comments, Facebook comments, email’s and the Livechat, come on over and check it out. th-cam.com/video/cTBXc_N4O1w/w-d-xo.html
im about to start school and i am watching your videos to get just a little understanding on HVAC before my class i pay for teach me but its always good to learn from different sources and different teachers

We need more technician people like you.
I love how very thorough you are.
Thanks
Another job well done, love all the details covered and the new digital display
Thanks bud!
Thank you TH-cam algorithm, you've made my day today!
Excllent video Chris! With an excellent explaination. Thanks man!!
Nice work! Good to see there is good service techs out there still. Many of them wouldn't have done half the things you did and just skated outta there.
Thanks for the nice words, I started making these videos to show my own service techs how I want them to perform their service calls. Than i decided to make them public because there is massive amount of people that do not look at the big picture.
i worked in a kitchen before that had the same exact problem, frost everywhere and especially around the door. The evaporator was directly in the middle of the ceiling and facing downward. Sometimes it would get so bad that the whole fan blades would be frozen and not spinning. Sometimes it would melt and drip to the floor where it would form a giant ice mountain (very safe). They said that the HVAC techs couldn't figure it out, but after working there for so long I figured they got a quote and said "screw that" especially since their station fridges constantly need to be refilled with refrigerant
One video showed up.... i had a curiosity... been binge watching since, even subbed to the channel. Now, I am ready for a waivered, ride along. (Hate missing some of the work that ends up on the editing floor.) Awsome job.👍
You are the king of getting repeat work! I bow down to you sir haha great vids mate
Thanks bud
Great videos man, learning alot from you just by watching. You're an awesome tech keep up the good work!

Great job,a professional ethical service tech.well done.i didn’t notice if you checked the door heater?also from experience almost all employees keep the freezer door cracked open because they fear getting locked inside
Same issue im getting for some of my coldroom hear in Qatar and its allot of humid here during summer,anyway good job its like a newly install coldroom the client will appreciate what you did.
thanks bud!
Nice job
Gaskets sometimes can be a pain like door heaters
Just had a walk in cooler act up only when it very cold outside
Ended up being a intermittent problem with low pressure control STICKING ONLY DURING FREEZING WEATHER OUTSIDE
RESPECT ON YOUR VIDEOS👍🏻 as refrigeration is always fun 😳
I like to use warm soapy water when installing door gaskets.
Excellent video sir!
thanks for watching bud!
Who else got this recommended?
*raises hand*
I did because I'm something of an industrial nerd.
FoxyKero Freon fox here . Showed up in “recommended for you “
Me too. But I was looking at ground heat pumps excessively day before so it make sense. I would watch it anyway, very cool. Another great channel of just doing things In the field: Andrew Camarata, excavations and other soil/ground/drainage related stuff by one man. Addictive.
Bypassed DTFD can cause the droplets on the ceiling. Staying in defrost too long. You can’t diagnose a system without superheat and subcooling.
This is How a Service Call With this issue SHOULD be Done ! Well done Chris & company! ( FTNGOT) unfortunately , 90% of customers will NOT Approve the cost to do this repair. ( Ftngot) - whenever i see frozen water droplets blown all across the ceiling guys u are looking at one of 2 things. most likely someone found a defective (DFTS) defrost termination switch/combination fan delay switch, did not have one on the truck and bypassed the DFTS or its just plain defective, replace it, so, what is going on is after the defrost cycle terminates the Drain pan still has water in it and the fans are coming on right after defrost Blowing any water on the coil or in the pan across the room. the box pulls down and freezes all that blown around water all over the room. u also want to make sure the drain line is clean and clear and drain line heater is fully functional. 90 percent of the time installing a New Fan delay switch / Defrost termination switch will solve this issue, but u also need to make sure All the water is leaving the drain pan within a few minutes. for customers that cannot or do not desire to drop all the cash at one time u could spread out this repair over time. replace the DFTS and check drain line first, in 3 months do a door closer, in 3 months do a door gasket. this spaces repairs over time for smaller customers and Keeps u coming back and can touch base with customers / good customer relations. FTngot = short for - For the new guys out there. Torn door gaskets are a Health department violation in california and a citable violation in california, so customers have to replace door gaskets unless they want thier business shut down- so those are a pretty easy sell and they stop doors from closing properly and cause all kinds of other problems units running all the time because the door is not closed , units shut off and come back on again too quickly stressing compressors short cycling, causing frozen evaporators on refrigerators etc, etc. good door seals are a must.
Door closer on this service call was also a standout- it definately needed replaced also.
Thanks for watching Phil, and thanks for adding your 10 cents. Those are some great points you made!!
Guys that are reading these comments listen to Phil and sub to his channel he has great content!
@@HVACRVIDEOS thanks Chris ! much appreciated .
Exactly...I’m having the same issue at a hospital that we do PM’s at. The building engineers swear that’s not the problem because they say the defrost termination switch works just fine and it’s defrosting. They don’t understand what the fan delay is there for. Those coils are supposed to get cold enough to freeze any residual water left on the coils after defrosting so that they don’t spray water all over the place when the fan kicks on. It’s hard to convince a building engineer that doesn’t know shit about how their unit is supposed to operate.

a costumer of ours tried to defrost it with a knife. 2 holes in the evaporator GG
A lot of good information in this video. I like it.💯
That's a quality repair, good job
It's nice to watch other craftsmen work. Something else which wasn't mentioned in the recap is that since the drip tray was misaligned and frozen up, it wasn't able to remove moisture from the freezer. Since the freezer is a sealed environment most of the time, the only way for moisture to escape is through condensate dripping off the exaporator and out through the drain during the defrost cycles. I would imagine that the moisture instrusion problem in the electrical boxes will be much reduced just by re-enabling the moisture egress path, but a surface mount replacement was certainly a very good idea!
Door seal is usually #1 problem with moisture and icing. Glad you found the other problems, like you said the job is 1 1/2 hours away from your base. The flat roof with standing water was a concern as well if a leak develops.
Love the troubleshooting and general diagnostics. Craftsman, regardless of specialty, have a way about them.
I do all kinds of DIY and recently had a residential 40+ year old GE refrigerator burp. Needless to say, over the last few days, I've been OD'ing on refrigeration theory, practice, engineering, and repair.
Thanks for putting in the effort to take us along on your professional endeavors! Highly interesting stuff for those of us with a mechanical bent.
Oh, and my 40+ year old GE refrigerator? It lives on to cool another day!
Really interesting to watch! Thanks a lot!
Good thing cutomer paid and happy.
Its very sad that here is south Ontario some customer dont want to spend money on their equipments but expect keep running . Eventually end up replacing their equipments.
But Its hard to convince some of them .
Good video. Thanks.
Another job well done fella. I especially liked the idea of trimming the seal to make it install. I would of still been there today trying to stuff that thing lol with a screwdriver.
Great video!! Love the fact that you examine everything before moving on to another job. I work at a fast moving company and they hate the fact that I take my time with services. Lol my response is how many call backs do I get? They reply hardly non. I say exactly. Lol
thanks bud!
“Big picture”. Excellent job! Thanks for sharing.
No, thank you for watching!
Great video. I'm going to keep in mind that controller cuz I work at a school district and I've been there for nine years and occasionally I have to take care of some low temperature problems. We have some walk-in coolers in a few freezers. I've been mostly HVAC my 35 year career. I use electronic controllers on the district's walk-in coolers because we need tighter temperature controls. The dixell alarm kit that you installed is something that I'm probably going to be using a lot more here cuz we have the same problems with the monitors. Silicone never does the job I always use foam fill and have a lot better success. I occasionally replace some of our equipment. I always use foam I never use silicone it never feels every little crack and you have to fill every single crack. That dixell controller that you put on there will be really good at the school district here for some of our problem boxes. Great video
Nice, well done. Really took care of everything instead of fixing one thing and hoping they are happy enough.
Thanks bud
Sweet i work in a hotel and we have this tipe of problems on the restaurant, thanks for the video!!!
That box was pretty set after this visit. Their looking pretty good for a nice long reliable system
This was super cool to watch I’m in HVAC school right now I’m wanting to go into refrigeration
Everyone should be wearing ear plugs when working with that walk in, especially when they do a walk-in clean, re-stalk and remove. Awesome repair!!

Great video and very thorough job. One suggestion: After too many times dragging a hose into a box I got a 50' pieces of 1/4" ice maker tubing. Added various adaptors to fit different water hookup scenarios and a shutoff at the end. It's lighter in weight, easier to pull off the truck, provides gentle spray on coils, takes up much less room and saves a lot of TIME with setup and tear down. Just a thought. Keep up the good work.
I used a 2 gallon pump up sprayer that I extended the hose on with a quick disconnect at the tank. Sometimes getting a hose where you need it wasn't worth the hassle.
Quality repair yo, tip my hat off to you sir 👍
Nice video! Enjoyed how throughout you are, keep it up brother!
Customer complaint: Their freezer is frosty inside. Um... Lol! Sorry, that hit me funny. It is nice to see that there are still people who know how things work such that they can properly diagnose and repair them. Nice work.
Ha ha thanks bud!
very good video, thank you for all steps diagnostic to completing
I know many walk-in freezers look alike, but this looks absolutely identical to one that was in a restaurant I worked in years ago.
Great video . I’m dealing with the same kind of problem with a faulty or disconnected limit switch and severe ice build up in the coil. I’m going back tomorrow to follow up and finish the call.
You are amazing
Refrigeration is my weakness
Learned so much from you
3 wire fan delay. Yup. A cheap part to replace regardless. If you have the coil sides cleaned and exposed, replace the 3wire fan delay.
It's a snap disc, it's been exposed to heat/cold and snapping away.
Definitely inspect the part and connections.
It would be a shame to get a call back because of the F.D failing after you were just there.
Best wishes!! Thank you for sharing!!👍😎😎
Very well explained !
Exactly what happens at our work. They leave the freezer door open all the time. I told them they need to keep that freezer door closed We have replaced four gaskets so far it is usually because the company who delivers of food keeps both doors open so they can bring them into the cooler are freezer
I usually find the hinge springs need to be replaced or adjusted on those type of hinges. You can get just the spring cartridges for not too much. Great job catching the limit switch.
Thanks bud!
Awesome job, I really enjoyed watching as always.
Thanks
