THEY SAID THE WALK IN FREEZER WAS TOO WARM

- This was a pretty typical walk in freezer service call that I get about twice a month across all my service locations. Even though I go thru this on a regular, I still treat each call as if it was my first!

First thing I noticed is the dry pendant sprinkler head sticking down in the wall in freezer lol. That’s installed completely wrong lol.
the double zip tie trick is fantastic. saw you do it a while ago and now i use it all the time
lol the ice looks so nice and smooth I don't even want to melt them😂
I forget if it was Technology Connections or ElectroBoom that did an explanation video on CFLs and the reasons they were so hated.
All florescent tubes have a heater filament on either end to bring the mercury inside the bulb up to vaporization temperature before it can form the plazma stream (e.g. floresce).
When the bulbs first come on in a cold environment, only some of the mercury vaporizes, so you end up with a weaker plasma stream.
I think TC did a video on why they were hated, EB also did a video on CFLs but just about how they work and he might have mentioned drawbacks of them as well. Funny I watched both of those videos fairly recently lol
@@MegaDysart Both are great channels
florescent lamps like it at around 40c or 105f on the tube itself. They get that warm by themselves no problem, but in a freezer...
If they are colder, all the gases, phosphorous coatings and stuff doesn't work that well, thats why they are dimmer and have a kind of wrong color temperature.
Fun fact, TC watches chris's videos.
Just started the video and instantly paused because I recognized this location. Last time they had a habit of tying the door open causing frost and you had to replace the door and frame because of rot.
I agree with you on that switch. With the fans running slow, there was a significant power drop across the switch which would have been heating it up.
This is the trade I’m going for very inspiring 💯
Thank you for another amazing video! 🍻😎
Within the defrost montage I noticed the sprinkler pipe wasn’t sealed inside the cooler. That could potentially add to the moisture getting inside.
And it could freeze if a wet pipe system
I believe they are full of air/gas. Once the device is broken, the water will flow in.
@@sergiomateo7671 that would be a dry wet system
@@THEBRAINANAYTOR not sure man. But that’s the way my brain work. You definitely can’t have water pipe in there for sure.
@@sergiomateo7671 no no. That’s what a wet dry system is. You’re correct. Those pipes are pressurized with air and there’s a valve with the same amount of pressure of water. When it pops. It flows.
That left condenser fan came to a pretty sharp halt when you turned the unit off at 11:09.
Noticed that as well, was about to make a comment on it.
Both fans seem like they will fail soon with the left one seeming to stop way faster.
Thank you for the wonderful advice as facilities maintenance i have to troubleshoot issues before we can submit a work order.. i have learned so much from you God Bless you
Thanks for the information. Your videos are helping me a lot.
Loved the 80's De-ice theme music ... Reminds me of the old VHS tapes we use to hide 🤣😅😂 Thx for sharing and keep the music ...
No worries, your awesome. Been watching for a long time, so your doing it right.
Why not write the total defrost current draw (as measured at the timer) when you commission a system. Then you only need to test individuals if it is low.
I like your real life breakdown fault finding videos. Electrical/Mechanical is my field with a bit of aircon. I have learned more from your videos than most of the so called courses I have been on. Thanks. All the best.
Bro your montage jams are amazing.....reference?
It's good to see you took a moment to power down and recharge the batteries at 5:51 😁. Keep up the great videos
Nice I thought he was making sure the drain pan didn't fill up too much and start leaking in the box but I like the way you think.
12:08 - In extreme cold these fluoros may even turn faint pinkish-purplish. They are filled with a very low pressure Ne-Ar filler gas mix with Hg vapor. The ionized Hg vapor is what gives a strong UV light, which the phosphor coating inside the tube converts into visible light. In extreme cold the Mercury vapor will condensate into very tiny droplets on the inner glass wall surface and other cold spots, and the gas charge will instead emit the characteristic pink-purple light of the filler gas mix, which does not radiate much UV light, thus won't make the inner phosphor coating to emit visible light. It will just partially block the filler gas glow. Once the tube warms up, the Mercury will go back into vapor state, and the tube will return to its normal brightness.
Good watch, learn stuff all the time, thank You!
Chris, have you seen the yellow vinyl "tarps" with a hose fitting for leaks, drips, etc? The pipe fitters use them at work where they don't want water on a food production area, but don't have a big volume of water. One of the smaller ones could be of benefit on jobs like this, as long as there's a drain nearby.
Roof Diaper or the PC name is Roof Leak Diverter
12:10 funny thing about the TL lights. modern leds lights actually get brighter the colder they are.
seeing those fans barely start up.. id say you made the right call. that's a bad connection in the limit switch
Your amazing brother may god bless you always. Your a staple on what it takes to do work the correct way
Great timelapse & insight into defrosting process for outsider to the job 👍
I appreciate you so much I’m going to buy your hat.
enjoy watching your channel from northern calif
Thanks bud
i like this view of your job the camera angle now I see what you have to go through this really does much better than the close-up view unless you need the bolt detail perfect angle this is a 10 out of a 10 video audio and video angle
EXACTLY!
10:11 that makes me laugh, always when you decide to get your meter out to check whats up all of the sudden it works again. Man if i got a penny every time that happend to me i would have about 6 penny's
When you know your equipment and how it operates....you don't always have to break out every gadget and gizmo fancy tool....you just know....because you've seen it a bunch of times before. Also you get to know the quirks of different manufacturers and their issues.
Sped up Ear cleaning at 5:50 guys. Great video as always
Dude talk about maximum satisfying powerwashing timelapses that was awesome!
Bring on the knowledge!
Thanks lot for sharing your experience,
I am following you from Paris, france
These videos are so informative
nice camera angel on the defrost
It seemed like that ice melted quickly. Seemed like it was a quick buildup of ice rather than the long slow buildup that creates that clear solid ice.
Why you sound proper too many seemed.
Great video, at 11:06 when the CFM's are coming to a stop, is the way they came to a stop in this video sign of the one on left going out? Also, I know you have mentioned it in your past videos that you just got it at a local home Depot, but do you have a model # for your spray wand hose attachment? Thing looks like it works awesome 👍
that spray wand is Orbit Max 8 pattern wand. i get them from my local Lowes. it also comes in a shorter fixed angle wand and a pistol grip nozzle. all have the same spray patterns , quarter turn thumb operated valve and less internal restriction than many other nozzles and wands. i do swimming pool service and maintenance and the pistol grip and flex head wand have been my go to for years.
Something says me a sprinkler (usually filled with water) and -18°C in the room is not the best of all possible combinations. The ice in the pipe will be thawed up by a fire though, but this could be a little to late. But there was surely a certified company installing this, so this won't be a problem, right?
Still the best hvacr channel out there. Still helping everyone to become a better tech. Keep up the great work!
Awesome video
I think someone needs to repair the dry pendant sprinkler head as well.
I want your music.
Almost fooled me into thinking those were ECM, until I realized I saw the silver caps strapped to the side, and I didn't hear the high pitch whine that a VFD usually creates. (and obviously when they didn't start spinning faster until they were at operating RPM.)
I'm split between fire systems and HVAC. I don't know what I want to do more.
You should design some sort of controller that detects the coil getting iced up and forces an extra defrost cycle
Customers probably won't want to spend the money
KE2 Therm
WHAT DO you think about having 6 instead of 5 defrost all at 45 min instead of 30 and 45,and checking the fan cycling with this cooler weather maybe head pressure too low,did not see head master. thanks for sharing,with your help mine have remained ice free,with bad doors and no walk in cooler before door.
If you know how to fix commercial refrigeration. Do you also know how to repair domestic fridges and freezers and fridge freezers?
Yeah I'm sure I could figure it out, but my business does not repair them
@@HVACRVIDEOS that is good. I didn't really expect your business to support that as I've known your channel about commercial only refrigerators
2:15 Does this mean that ideally these restaurants would need to have some sort of ice sensor that detects when the ice becomes to thick and initiates out of order defrost cycles? This question may be a bit too theoretical since I do not know if an ice sensor exists.
Maybe a once a week super defrost would work.
So the limit switch will do early defrost termination as well as works as a fan delay ?
Yes it will do both
how does that sprinkler head in there live, is it a dry system ?
My first act on 'it's frozen up' was to rewind the video and look for a bungie cord at the door.
Have you ever tried using a steam cleaner to defrost the units?
No I actually havent
Wonder if it would work and be safe. Hot steam would be less water and possibly speed it up? I did research and couldn’t find anyone who made anything for this idea.
Your awesome
Good video
haven't been to this location for awhile
love the 1980s music
Big picture diagnosis master
Defrosting montage! Cool.
Why are you people putting the controls on the roof at the condensing unit? Isnt it easier to put it at the box?
How is the home HVAC upgrade going?
The next video is coming soon, it will be about blower door testing, duct testing and some minor air sealing
0:24 - "...and it's all frozen up. OK! So we're going to, uh..." lecture the staff AGAIN about leaving the door open for extended times? 😛
3:55 - Is there any insulation where the sprinkler pipe penetrates the roof of the box? I notice the trim ring is sitting on top of the head itself...
did you notice how fast the left condenser fan motor stopped at 11:10 ? bearing seems not that good... just sayin....
Hi how are you wake in freezar tamprachar is sloy sloy wat rezan discharge 290 psi and suction 25 psi tamprachar is 0 to -1 time is 30 mint you not mind my inglash is week
I took a short cut with a industrial dishwasher almost died accidently touched the heater element prongs ouch 240volts
💪👍🙏🇺🇸❄ nice work
Time to sell them curtains as well.
What's wrong with people leaving the doors open? Do ya do that at home with your own fridge/freezer? I bet not so, why do it at work? Someone needs to intergrade a door open interlock where if the doors open for more then a set time it completely shuts off tell the door is shut..
I think a display in the manager's office with "you just wasted completely useless 10 €/$/whatever currency of energy costs during the last 60 Minutes by leaving the freezer door open" would be much more effective...
Hey Chris, the matrix revolution ? I sound and look like larry fishburne again? But what's up with all the solar panels? A one dollar cold beer sound good? I'm like dr dre might pop a cap another cap on a cold one? Love buddy, might sound a little queer again? but it is a joy good show.
again hit me! freeze, see the woman in the red dress? Then get your credit card.
systems check.
_Brazing montage music_ hath become _de-icing montage music._
Lo.
man those things are always dirty
mr.chris I wrote to you before on TH-cam channel? I'm about to start my job at Wendy's as a maintenance technician which involves me repairing ice makers walk in coolers and ovens as well as fryers, will you accept my offer for 100 dollars a month to call you for tech support? Some Wendy's location have hozaki ice makers and they look intimidating 😂 is it ok to call you? I hope you read your messages on here and not just press the like button randomly.
I know you busy please forgive me for sounding rude good sir
"Why do all your videos have the same title?"
"Why do you all keep leaving the door open?"
There are not so much possibilitys for a fault - "too warm" or "too cold" is the most common problem. Only difference are good managers (On e.g.Wednesday:"Oh, there is a problem, please fix this ASAP, next day is sufficient") or bad managers("It is saturday evening right now, please hurry and fix this immediately, we ignored this problem only 4 days in a row after all!)
I could never live in California with the rules they have and their Governer.
I like everything else in your videos, except that too loud cheesy music on top of everything. I'd rather hear just water dripping or flame hissing or nothing at all.
469 Thumbs uP
What's with the 80's porn style music in the background as you were defrosting that coil🤔😏🥶
Because it was coil defrosting p0rn 🤷♂️
There would be a lot more hair if it was 80's porn. Just sayin.

Your videos are played out
Thanks for watching bud
