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

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.)

Thank you!

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.

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

It's one of the best videos I've ever seen on defrost clocks. You're an awesome teacher, mate!

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!

Very few guys on KZread 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.

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.

Thank you mate. You are a star 🌟. I appreciate people like you who take their time and share the knowledge. Respect 🇬🇧

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

This is the best walk in freezer explanation video

HANDS DOWN THE BEST! Good looking out POST MORE VIDEOS

currently doing a cooler project, and this is what I have been looking for. Thank you for taking your time

Excellent teaching method very good approach and fantastic analogy please continue to help you are a gentleman

Very good and simple explanation. Thanks.

I am Brazilian I work in the refrigeration area I am a refrigeration technical I work in the area for over 15 years and I really like your video s

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.

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.

You are a natural educator

New to refrigeration and this video saved me today. Wow. Just did everything you did and boom, problem solved. Thanks for making these.

Nest explanation on that defrost I've seen.

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

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

I'm new to the commercial side. Coming from the residential side these videos are helping.

I appreciate this video was looking for a time clock refresher video good job bro

Thank you so much about you explained the defrost timer work.

Great video, took a 2-3 year break and fixing to start up doing repair work again

Very professional presentation of the walk in Freezer sequence. Good job.. thank you

Finally I found these video....now i understand how to work that timer...👍👍👍❤❤❤❤...thanks a lot .....

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!

The best teacher and an excellent technician, thanks man. I can't hold the multitester probes on one hand.

I love your vids man, you explain everything very thoroughly and well. As someone whos interest in getting into HVAC your videos are very useful and informative.

It's great that you give a lot of information. I think a lot of us are here to learn, so your format is perfect. If I'm not learning something, I usually skip through videos. I actually skipped back a few times to make sure I understood. Subbed also.

They will sing songs about you one day my good sir. Love your videos! I especially appreciate this one because for whatever reason, this doesn’t stick lol. I hope that changes now. Thank you!

Love your videos! My son does this and he now has been at U of Iowa Hospitals and clinics ; but he did what you do years ago! Thank you for your time doing these videos!

I watch your videos all the time, watching you has made me a better tech. Much Blessings Brother

Thanks Chris for the little ref class that was great explanation GOD bless you and your family too.🙏🙏

One of the best logical explanation of defrost timer . Thanks to make it so easy.

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 KZread station. Thanks.

Thanks so much I really enjoyed the video it really taught me something about commercial refrigeration.I am a service technician doing AC and chiller on buildings. That really help me and would like to thank you for sharing the taught with us .

Freakin love u man! TYVM I can't express how much I appreciate u taking the time to make these videos. God bless u and ur family

Thank you sir for the lecture. Alot of people don't like to share the knowledge.

Your videos are a godsend. I do facility maintenance and I'm the only guy on my team with HVAC training, but I never learned about medium/low temp stuff. We have about 7-8 walk-ins. The first time I looked at one of the condensing units, I didn't even know what a low pressure control was or did.

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.

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.

Thank you so much man I’m a 19 year old service tech for refrigeration company in sf and watching your vids have helped me become a killer tech

I have a deep respect for a person like you , have a deep respect for a person like you, have a deep respect for a person like you, THANKS

Thank you very much. Your videos are gold.

Great explanation. Thanks for the detail. I'm going into my third year in the HVACR industry. The company I work for does similar work as to yours and its good to see someone willing to share. Thanks for the content. Looking forward to future videos.

I agree with others... great thorough job explaining not just how but why things are done the way they are... gives better in depth understanding... just a great job!!

you are an absolute excellent proctor explaining !!! the best ive seen on you tube. thanks from one tech to another for being so entailed and informational !!!!!

Really good video details than everyone,finally i understand how the defrost timer works thank you

Excellent video. Worked on a walk in today and was puzzled. Not anymore. Keep up the good work.

Stumbled upon your channel and really like how thorough you are with your service calls and explaining how things work and the process you go through. I’m new to the refrigeration part of the trade, got put on call this year. So I’m just trying to learn whatever I can. Glad I found your channel.

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????

GREAT VIDEO. Especially good for those of us who worked on refrigeration and stopped like 15 years back. Now scrambling for a quick refreshing due to new service contract that includes light refrigeration. I’m going to watch this one several times this week or till I feel comfortable again. Thank you for posting this video ✌🏽

Thank you for your time and specially your knowledge ! I could never eliminate those drips on the ceiling of walking cooler or freezer ! Of course no one explained it to me !! Now I know !!! Happy Easter 2019

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.

Awesome explanation on how defrost clocks work with refrigeration application we haven't got to learn about those yet until this next term when we go back January 13th it's good to have a little heads up on this thanks a lot

Your the best. I always learn something from your videos.

Good job bro I learn more gad bless you keep going

What an awesomely explained video. Thanks for taking your time to make these videos bro!!

Thank you for the thorough, simple explanation. I understand now.

Good Job. Thank you for all the good information in the video.

Thank you.I learned something as a starter

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.
