Walk In Freezer 18 Month Old Compressor IS BLOWN... WHY?!?!?!

[@stheodro]

HVAC Overtime sent me here love this channel no dumb music here, just straight to business

[@REFRIGERATIONKITCHENEQTECH]

Lol, thanks! Met some awesome techs from the O/T page, it’s a great page.

[@ricardov8249]

this is first vid of yours I've seen. Explanation and steps just like in the field but done right. Great job on putting vid together hope hope it helps new and old techs.

[@REFRIGERATIONKITCHENEQTECH]

My goal is to get my techs trained one video at a time. It has really helped shorten their learning curve. Thanks for the kind works.

[@navjotsingh-lr6nn]

As first year apprentice I learned so many things from you . Thank you

[@REFRIGERATIONKITCHENEQTECH]

Glad to help

I have never heard about the stress test. I will be trying that out, thanks.

Just found your channel and subscribed, I'm also a refrigeration and catering engineer (in the UK) and was impressed with with your breakdown and how you explained you logic. 👊

[@ReliableHVACR]

Nice breakdown, good stuff

[@REFRIGERATIONKITCHENEQTECH]

Thanks

[@kennethlobo4420]

First time watching your channel. Great tips for fault finding,Thank U.could u do a detail video on knowing your saturation temperatures,which u should during the last segment of the video

[@REFRIGERATIONKITCHENEQTECH]

Here is a video I did explaining saturation temperatures Reach In Cooler Refrigeration Pressures Explained

[@brianprelgo4553]

Great video! Big picture diagnosis

[@neilvestervictor180]

great job again

[@REFRIGERATIONKITCHENEQTECH]

Thanks!

[@refrigerationconfidential4376]

Great editing for the explanation on this.. great work man

[@REFRIGERATIONKITCHENEQTECH]

Thanks for watching

[@simohvac9222]

great explanation

[@jfs520]

Phenomenal video thank you for sharing

[@randomrefrigeration4564]

You have to pull the head to diagnose that compressor You may have had a failed CCH and you had slugging or flood back while running or on start ups If you also pull the oil pump and check the crank bearings I bet you have slack which caused the motor to touch down hence shorting out the L1 winding If you read the directions of that quick test the compressor must be running while performing the test Your videos are great just giving a little advise Great videos thank you for taking the time to create them

[@REFRIGERATIONKITCHENEQTECH]

Appreciate the feedback. I’ve never taken one of these apart but I think I will on the next on, always eager to learn new things. How would I get oil into the bottle if the compressor is running?

[@SombraLocs]

Great video!

[@davejohnsonnola2758]

"Creepy Dave" from the internet? Hmmm I may resemble that remark! Was that a Trenton unit? That schematic looked familiar. Missed the high school chem lab test for acid when watching this a couple months ago.... like that much more than the 2 second spritz tester.... Good stuff, hope you continue to post.

[@REFRIGERATIONKITCHENEQTECH]

Lol thanks Dave!

[@mohalfur]

Damn this is good. Greetings from Norway!

[@REFRIGERATIONKITCHENEQTECH]

Thanks!

[@farashvac]

Hey man , shouldn’t your sat temp be -20, or some say -10 if it’s for a freezer because you want to maintain 0F, I get coolers confused too?

[@shine-cg9uf]

Great 📹. !

[@REFRIGERATIONKITCHENEQTECH]

Thank you

[@gohan192]

Your video and the great detail are amazing. Thank You. Thumb up and subscribe.

[@MariosACandRefrigeration]

liquid is what killed the compressor,block the condenser coil when charging to raise head psi clear glass, then add winter charge.also you need refrigerant in system if you are going to use the leak detector, to check for leaks,not nitrogen.

[@REFRIGERATIONKITCHENEQTECH]

Yes there was a trace amount of refrigerant during the leak test. Thanks for the comment and advice.

[@harrydickson4575]

👍👍👍

[@HVACRDUDE]

Or you can block the condenser to 95-100° condensing and charge to a full glass and your done....

[@REFRIGERATIONKITCHENEQTECH]

Yup, the point I was trying to make was knowing what your saturation temp should be in case there is no sight glass (ie- ice machine or a small prep table with no sight glass) Thanks for watching!

If you knew the compressor wasn't running it would have been much simpler to just meter the feed into the compressor at the compressor. The drawing wasn't relevant for this. What the hell was the point checking the contactor first???? Work smart not hard buddy. Checking the feed at the compressor would have told you what the problem was. Checking the contactor first meant you still needed to check the feed at the compressor so checking the contactor was totally redundant and pointless. This was not very clever diagnosis. You never needed to check the drawing at all. Thank god you had enough brains to know you didn't need to disconnect both sides of the heater for the impedance test. If you had I'd be telling you it maybe isn't a very good idea to upload any more videos.

[@REFRIGERATIONKITCHENEQTECH]

This is a training video for my techs. Most of our refrigeration techs are pretty green so I always teach them to check incoming power (especially on 3 phase). Checking amp draw was to show that the compressor was going off on overload as you can’t really hear the compressor running then shutting off in the video. Yes I mentioned to open up the circuit to check resistance, someone new might not know that. These are training videos for our newer techs so they can get used to using a schematic. I’m sure when you started in the trade someone had to teach you. Unless you are one of those techs who started in the trade 18 and knew everything. If that’s the case, good on you, you are much smarter than I’ll ever be.

[@johnrauner2515]

@@REFRIGERATIONKITCHENEQTECH I'm not in the trade. I am a Sound Engineer by profession. But I've also worked in fairly technical positions including automation of emergency generators. All the same rules apply. Don't waste your time checking the switch/contactor or if all 3 phases are hot. Check the feed at the point of suspicion. That will tell you there and then if you've found the fault. You might have to work your way backwards to the blown fuse or faulty contactor. But what ever test points you use, they should always be in order of giving you as much information as possible from one location, as well as eliminating as many failure points as possible. Otherwise you just spend your time double handing stuff you really don't need too if you've tested in the correct order in the first place. It's all very well working systematically but this approach can waste an awful lot of time. If you tested at the compressor you'd know the phases are hot or not and that the contactor is good or not. And if the compressor feed is hot then you've found the failure. The drawings are for when things get complicated and you need to know where to find something that isn't sitting out in the open. The drawings should never be what you refer to before doing anything with a fault like this. If the compressor has failed then test the compressor.

[@REFRIGERATIONKITCHENEQTECH]

Interesting to see someone in a different field use similar techniques. I always teach to check incoming power, a lot of newer techs won’t do this and start to work backwards only to find they dropped a phase. Amp draw needs to be taken to see if the compressor is failing on locked rotor or if the overload is opening to early. IE- if the overload was opening up at 6A as opposed to 39A, the overload is bad. That is a $200 repair vs a $6000-$7000 repair. But yes I full agree, find the load and work backwards.

[@davejohnsonnola7908]

@@johnrauner2515 if you had a clue as to what you are pompously pontificating about, you would know it is very easy to check at the contactor first, instead of breaking open a brittle plastic compressor connection on a roof in pre-dawn hours at near zero degrees ambient. These videos are for training his techs and graciously allows public viewing to share knowledge and teach other techs in the restaurant equipment and ac trades. Even though I have done much of the same work for years, this old dog is still learning from these videos.

[@johnrauner2515]

@@davejohnsonnola7908 I had assumed common sense would be applied. Obviously if the contactors and control equipment are inside and far easier to access then they should be the first test point. Jesus mate, calm down.

[@coldfinger459sub0]

Just subscribe to your channel very good Contant. I do small residential and commercial HVAC no refrigeration. But always watching somebody else’s diagnostic methods and procedures will always aid in hiring yourself education and tuning in your own practices to a higher level. Thank you very much for taking your time and your patience to edit and explain your video diagnosis procedures . Something I wish I could do in my videos but I have way too much work.

[@REFRIGERATIONKITCHENEQTECH]

Lol, I hear that, have not made a video since everything reopened, no time
