Walk-in refrigerators and freezers are very large, insulated, enclosed spaces used to store and/or display refrigerated or frozen food or other perishable goods. They are used primarily in the food service and food sales industry.
A Walk-in cooler is basically a large scale refrigerator - similar to what you have at home - except you can walk into this one! Every restaurant and fast food chain has a Walk-in cooler and it’s where they store all their refrigerated foods. Unlike a residential refrigerator though, a Walk-in cooler has a lot stronger refrigeration system that allows them to keep their food stored at optimal temperatures in order to meet certain FDA standards and to ensure that it passes local safety and food handling codes.
Businesses from a wide variety of market segments use Walk-in coolers from Floral Boutiques to Breweries to Medical Research Facilities. Walk-in boxes come in all shapes and sizes and depending on the business’s needs, a Walk-in box can come with a lot of unique add-ons and accessories such as thermometers and temperature alarms that monitor temperature inside the box. If a business needs more than just a Walk-in Cooler, they can order a Walk-in Freezer or a Walk-in Combo Box which features to sections inside the box, one cooler and one freezer section.
Walk-ins are constructed using panels. Walk-in Box panels easily lock into place via cam lock and can be installed right over most flooring’s (though you can purchase a Walk-in Box floor separately).
A typical Walk-in Box can range anywhere from thousands of dollars to tens of thousands of dollars depending on many factors such as size, horsepower of Refrigeration unit, add-ons, panel thickness, location (indoor and outdoor) etc.

Thx for the confirmation. I've guessed from the start that it could be the capacitor when you mentioned that the compressor was trying to start. Right now, im in school for hvac and subscribed and definitely going to watch your service call videos to learn some more 😊.
fantastic job!! I really appreciate how thorough you are w your craft & make sure you do it RIGHT & CLEAN & WELL. TY JMT🌟
Thank you! Stay tuned for new videos every week🔧
The proper and ( SAFE ) way to discharge a capacitor is to set your meter on D/C voltage and put your probes on cap, and It will slowly start to drain it. I won 50 bucks off a guy one time when I told him I could OHM out a capacitor and find out if it's good or not. He goes I don't give a fk who taught you refrigeration you can't ohm out a cap. So we go to his van he get's out a cap I take his meter set to DC and drain it. Then I go NOW I am going to set your meter to Ohms and use your 9 volt battery in your meter to charge this capacitor If it's good you will start to see the readings rise which it did because it was new. After he picked his jaw up off the ground and handed me 50 bucks he drove off highly upset.
Damn bro thanks for the tip. gonna try me to score 50 bucks as well
Love it man. I would be one of those guys to double check to make sure if the part is 100% bad but love your trouble shooting process
Hey jumperman great videos I’m currently at the tail end of my HVACR program and I have to say your videos are very help and gives a good insight on what day to day service calls look like. Thanks
Same here
I just started my program but im excited
Same here 💪🏽🙌🏼👌🏽
You are really good man. I watch this several time.
You too man.
I was looking for this kind of explanation and demonstration that is very rare.
Hope to see the video when you did the work on this unit.
Well done bro.
Top man
Love those field piece probes a must for any real tech.
Interesting and helpful video. Great job as always.
Thank you! Appreciate your comment & support 🙌🔧⚡
Watched this video in my tech school. Thank you for sharing.
Good job with fault finding, and you are right wires not looking good. Wiring must be neat and easy to follow. Please share your follow up video links.. Thank you.
Nice work and great integrity
Always great content my man!
Thank you brother! Stay tuned for new videos every week🔧⚡️🤙
Thank you for the videos Jumperman Tech , i would some videos on BMS 💯
Good details in describing everything
Great job my friend lots to learn share ...❤
You the man bro keep knocking them down
Thank you! Stay tuned for new videos every week🔧⚡️
Right on man great job

Good video. When you have a potential relay there should be a bleed resister on the start capacity.
💯 safety first! Thank you! Stay tuned for new videos every week🔧
Great video
Thank you! Appreciate the feedback🙏Stay tuned for new videos every week 🔧⚡
Hey Boss excellent breakdown, i have a question, I'm studying for a test which type of cartridge fuse used in a industrial refrigeration one time fuse, time delay fuse, tube fuse with reset or plug fuse with reset?
Should have slugged some refrigerant in it to keep their food cold till the next weekday then come back and do a leak search
That’s probably what he did off camera. It’s illegal to do that if you know there’s a leak in the system.
It's illegal? Really?
@stangaloski4208 its most definitely illegal in Europe anyway as if you know its leaking you might aswel vent refrigerant out to atmosphere
In the United States it needs to exceed a leak rate for it to need to be condemned
Ur not supposed to do dat goofy
Nice Video, I enjoyed it. But seriously?? A light with a cord and plug.
Thank you! Haha I always use the M12 cordless drop light but it went missing so I went with the cord! Lol. Hate using a cord😂 Stay tuned for new videos every week 🔧⚡
I noticed at the 4:22 time stamp you stated even though the system was marked as R-12, it was actually using R-134a. I understand that your reasoning for that statement was the phaseout of R-12 many years ago. However, if that system was actually using R-134a as you stated, it should have been CLEARLY remarked by the contractor that did the work with R-134a identifiers to indicate a refrigerant retrofit took place on the system. That is standard procedure for all refrigerant retrofits. Since that wasn't done, many technicians would think that was an old R-12 system that never went through a retrofit. Also, the low pressure switch setpoints would tell a technician if the cut-in and differential setpoints were set on the correct setpoints for the refrigerant type being used. I would look at those setpoints to see if they were truly set up for R-134a or if the setpoints were set up for R-12 pressure/temperature. That system could just be an old system that has stood the test of time and still has R-12 in it. I use the phrase "stood the test of time" until now that you were dispatched on to this service call where it has obviously finally shut down.
Very good points
Nice job
Thank you! Stay tuned for new videos every week🔧⚡️
Are they using a boiler for heat add for the loop? Anytime i work on a coaxial system i always do a quick backflush, unless its glycol. It takes a few minutes and very little amount of tools ( i don't disagree with your methods at all ) that unit needs some help
I am interested in learning more about this walk in freezers. I like the way you explained it. What of brad and kind of tools you use to check the high and low on the compressor?
What refrigerant was that system using?
Jumper man,are jumper man tech cause you are a master jump roper?
To the wall next fly please and thank you
I would have fixed it on the spot.. Id have found the leak, fixed the leak, reclaimed the system, and recharged it. No need for a second service call.
Most people would reclaim it then repair and recharge it instead of repairing it, reclaiming it then recharging it.
If it were me, I'm built different, so it wouldn't be problem
Those compressors are not cheap to put a titen 2.60 $ instead of usa hd for $6.00 I would not take the chance.thanks for the vid,keep posting.
Nice man , i wanna put my foot in a field may i work with you couple times for free just to learn more ?
Jump man where you located
You need to cover or remove the food products below.
Good advice. Thank you! Stay tuned for new videos every week🔧⚡️
I didn't see the link in the description for the follow-up video.
Thanks for pointing that out & for watching! Stay tuned for new videos every week🔧⚡️

Why no 409a?
What's the cost of job like that
I got freezer room but it does not go less than 10 degrees.
If you would like to learn something about refrigeration, you can ask.
Just a question have you been doing this long? or are you a rookie
Follow up on this?
0:01 light switch
134a
I recon that both caps got destroyed because of the compressor was short cycling constantly.
💪🇺🇸👍❄
Thank you! 🙏🙌🇺🇲🔧⚡
What can you earn as a technician
after hours heading to a wine cellar not working, first time working on one 😅
Just another day in paradise 🥂😂 Stay tuned for new videos every week🔧
Prefer jobs that are routine
This industry it’s always a different thing
You should use R422B is compatible with R 22 mineral oil. R134A is POE OIL
This was not a R22 system. It was a R12 system and the replacement is R134a👍Thanks for watching!
@@JumpermanTech only with an oil change kiddo. If you're not replacing the oil then you should use 209 and not 134
Where was leak.i bet it was on evap
Checking pressures is not the first thing you should do buddy
The last thing a tech should do is open up the system, even to just hook up a probe
Yeah, unless that's what the problem is. Then it should be the first thing.
you should never discharge a start cap like that...use your meter or a resistor.
Real techs don’t use shitwaukee tools
Should have top off with refrigerant . Full siteglass. 134 a tefrigerant. Discharged the compacitor with a screw driver on both terminals.
