Walk in Freezer service call (electric defrost explained)

[@bradmironik6137]

This video has been the most thorough in explaining the sequence of operation for the defrost cycle. Keep up the good work.

[@hg2.]

Yes -- this is a "start here" and "refresh here" video for defrost and walk-in coolers/refers. (I think restaurant and store owners lose sleep over their refers quitting and losing $000s on spoiled food.)

[@kennethlobo4420]

I agree

[@Rayram555]

I have a deep respect for a person like you, because of you sharing your knowledge and having the talent to articulate the subject.

[@HVACRVIDEOS]

Thank you!

[@theprocessor8023]

when you get old and cant get do those things anymore, definitely you'll be a very very good teacher. you explain a lot way better. congrats.

[@clifforddang5947]

You can tell how competent someone is at their job by the confidence in their speaking tone and you sir sound really confident!!! thumbs up!

[@MrFreaktape]

Bro I never had a mentor before but you are one of best services tech and Refrigeration business man hones. That I see on KZbin and the field just give thumbs up. I learnt things to do to cut back my call backs.

[@johnmiller102]

Great explanation. You should consider going in to teaching after you get tired of the daily grind of service work.

[@JulesODwyer]

Very few guys on KZbin are good at Explaining thoroughly what is going on in a System,plenty can fix and solve the issue but the actual Explaining of all the Functions and Sequence of Operation of whatever they are working on is True Teaching. It is very rare to find a Super Tech and Teacher in One.Great Job coming from a 63 yr old Tech still working and Learning every single day.

[@gonzalotavares65]

I've been doing residential work for two years and just barely got into refrigeration. The way you explain things makes so much sense to me. Whenever I have a problem or I'm stuck at a job, I always come back and watch your videos. Thank you so much for these videos and keep them coming.

[@jaykeller1]

by far the BEST explaination for the sequence of operation on a deep freezer cooler sir! BRAVO!

[@EnjoyCalculus]

The good ole defrost termination fan delay. Great explanation and video

[@letshavefunletshavefun8649]

Best explanation men. Thanks for the details. Deep respect for best tech like you.

[@jeffwallace4251]

Thank you brother!!!!! Your video helped more than you know! I've been fighting with a walk-in freezer for the last week I was about to give up. I thank you for the video

[@danielcarter305]

Chris, your explanation of the reason why they have defrost clocks reminded me of when I we a kid and used to unload the delivery truck at McDonald's. The air in the frozen section was so cold that on hot summer days, it would actually snow in front of the trailer door.

[@NathanVogt]

I have let the smoke out of a lot of new parts because of not fully diagnosing the root of the problem. Great video not a HVAC guy but I am a systems guy and can really appreciate the process.

[@365survive]

Your videos are helping me so much man, you don’t know how much I appreciate it. Just started my new career in refrigeration tech work. Been doing residential AC TECH for two years and started to get bored and wanted to learn everything. Your videos are great.

[@alexzapata692]

Watching this video literally helped me finally connect the dots in refrigeration. At the time clock where your explaining 3 is defrost 4 is refrigeration 1 n 2 are your high voltage line and N your neutral and X is defrost termination than explaining the theory behind the limit switches into a light switch concept was very practical. Thank you.

[@petermichaelgreen]

Note: the "N" terminal in the unit shown here isn't actually a neutral, it's one of the phases, hence why he is measuring 208V between it and other terminals. I'm no HVAC guy but I presume presume they set it up like this with 208V control circuitry so the refrigeration unit as a whole doesn't need a neutral.

[@robertarnold6672]

One of your best videos yet! Well presented & even a refrigeration novice like me was able to clearly understand all the concepts concerning the time clock & its operation. A very valuable training tool indeed!

[@ivoryjohnson4662]

Thank you for explaining the functions. Plus you take the time to diagnose why it failed

[@Sunrise_HVAC]

I had this explained to me before and it was not like that. Your da man when it comes to explaining. I am Just getting started in Refrigeration from Resi and I use your videos all the time I run into an issue. Will give you tons of credit on my KZbin station. Thanks.

Thanks for the gems of wisdom. You are a great teacher & it comes naturally! I’m guessing you had a great mentor/teacher who gave you the gift that keeps giving....knowledge. Keep em coming!

[@HVACRVIDEOS]

I made a bunch of mistakes when I was coming up, I was taught by an old school tech that taught me a bunch of the old school ways, such as beer can cold and we never used a recovery machine. We charged AC's to 275#/65# regardless of the outdoor temp and indoor wet bulb. I always knew something wasn't right about that method but just never challenged authority. Eventually when the internet came about I started reading and realized it was all wrong! But In the middle of all that bad advice I got a bunch of good stuff too. I learned people skills,and sound mechanical troubleshooting skills so I ask myself was it all bad advice????

[@JulesODwyer]

[@guy872]

Chris, Just want to say many thanks for posting these dumbed down versions like this! I just happened to stumble across your channel one day and have been hooked on your videos since. The way you explain things and don't whine and complain all the time makes them very enjoyable. I am sure a lot of your viewers are seasoned pros that already know all of this information. But the only thing that I knew about HVAC before watching your videos was it makes summers bearable and keeps food cold. So as someone with no knowledge of any of this stuff it really helps me understand how it is all working together. I find it all very fascinating and am truly appreciative of the work you do. I have been considering going to school to learn this trade as it seems very rewarding at times. Anyways just wanted to say thank you and hope you have a very merry Christmas! -Ryan from Ohio

[@HVACRVIDEOS]

Right on bud thanks for watching and you should definetly look into the trade, I love it and it's very rewarding. Also Check out Rick's channel Northwest Ohio HVAC he is usually a recommended channel at the end of my videos.

[@DominiKing32]

Thank you for your videos. I appreciate them. I hope god blesses you and your family this year.

[@koolhub5891]

I like how you took your time and did a systematic check of the electrical circuits. Checking for resistance in the terminal wires of the defrost clock, with the power off and then turning the switch gear disconnect back on, and pushing the compressor contactor in that power on the compressor and condenser fan. Basically the compressor and fan are wired in a parallel circuit, by doing this the defrost clock is faulty . You check the condenser fan motor, Commerical Ice boxes have a small defrost clock in them and electric heaters mounted inside the Evaporator coil, I used to work on those units, and to check to see if the unit went into defrost, I would turn the defrost clock wise, and hear a click the compressor and both evaporator and condenser fans will shut off and the unit will go into defrost, leers units and others did not have a fan limited switch and defrost limited switch or a electric heat safe limited switch, but it was easy to service and work on too.

[@HVACRVIDEOS]

Right on glad to help bud

[@for7hyp3]

Personally I think it would be a good idea to have the defrost heater on its own seperate contactor and have the timer control the coil rather then running it thought the timer. While the timer can handle the current if something went wrong with the heater and it started over amping then it can easily overload and burn up the relays in the timer. If you used a contactor that was rated 10-15 amps higher then the load of the heater it could easily handle the over amping and neither the timer or contactor would get damaged. Adding a properly rated fuse in line with the contactor will add an extra layer of safety that can protect the contactor meaning if the heater shorts or something you will most likely only have to replace a couple fuses instead of a timer.
