No one has the most clear explanation like this gentleman. Big help 🙏

Who would of thought that 3 years later your video will help some one on the field

Stumbled on this years later, you really do have a talent explaining things. Hope to see you do more explanation videos

Far and away THE best explanation of defrost clock operation that I have ever seen.

This is the best - detailed schematic explanation I have seen on youtube.

Yes…a fabulous description for the process that is easy to understand. Many thanks!

I absolutely love your schematic walkthroughs. Honestly I think you do the best job I've seen. Very useful I literally sent this video to a couple of our guys that are very green. Your style of color coordination and proper flow is pretty awesome. Would love to see a ton more

Beautifully explained. I thank you 👏🏼👌🏼

Took me many many hours over several years to teach myself to completely understand freezer wiring. too bad I didnt find these tutorials years ago. good refresher course

Thanks for this videos man

I could never understand it until I seen you using this schematic method. Thank you.

Thankyou for this guide. As an ac guy coming into refrigeration this helped a lot

I owe my life to this video….!

I don't speak english very well but, however, i got it him. Thanks buddy to help us!

I’m not speaking good English. U make thing so ez .I can understand what u mean . Best explains

Amazing explanation thank you

THIS VIDEO SAVED MY LIFE

Awesome video.

Thee best explanation! Thanks man frfr

Excellent explanation!!!!

very good walkthrough help me very much thank you for your time making this void.

Thanks you for sharing 😮😊 great explain deep details

Thanks for the information. I’m just learning refrigeration right now. I’m using Interplay Learning and the simulation training doesn’t really say what that defrost termination X does.

Thank you for the elaborated explanation of controls and schematic. I really don't see tech sharing indepth knowledge like you did. One thing I would like to mention here is that the fans are cut off during a defrost cycel for two reasons. One you explained but the second most important reason is not to blow hot air in the room while evaporator is going through a defrost cycle as this will cause the room temperature to rise and that will be questionable; for example for a blood storage rooms at -40c or plasma storgare such spikes (rise in room temp) would be registered on a chart which is a problem. Therefore, we turn off the fan while defrost heaters are melding down the frosted coil through electrical heaters or Hot Gas Bypass system. With the fans turned off the coils get defrosted effectively and not causing room temperature to rise beyond tolerable degress of temperature. Your explanation with the circuitary was "Professional", I really recorded this video as a reference for our technician to see and learn. Thank you for sharing. I liked your video.

Hi you are the best of the best

love it thx

Very good explanation.👍

Thank you

Great video bro thank you

Well done 👍

Thank you sir.

Great video! Much appreciated. Would you be able to provide us with a link to the schematic in the video?

The compressor interlock is to prevent the electric heating energy while the compressor is in the pump down process.

Great explanation! Wish I had this in beginning! I have been repairing walkins for almost a decade now. Quick question tho, how far north do you live since your doing an hour of defrost time? I set the time about 25-40mins depending on location of walkin. Have had too many terminations go bad and luckily had the time failsafe without heating up box too much.

Thanks for this great explanation i have installed freezer fan doesn’t come on i have replace fan delay switch still same what should be problem thanks

Hi Anthony, Cool videos man, is there a simple diagram that includes a switch that turns the fans off. I've seen three recently in the last week. Perhaps there is a book that you could refer me to. These units in particular have to hot wire coming from up in the roof. Thanks a lot.

Could you explain what your LC does on the digital controller exactly? I still don't understand

How do you get voltage on a closed switch is it because of the load? I’m just asking because I’m new to this I don’t understand I thought a closed switch has no potential difference

but i am still in doubt on how to wire LP & HP switch i am looking forward to see Lp switch wiring diagram

What software did you use for the demostration?

Is there a complete circuit diagram of a walk in freezer or chiller?

I know they basically do the same thing , but do you have a video on this same thing only on a mini fridge with a top freezer ?

Can you DUE the same schematic for 3 phase power please. Great content well executed iam fan of your wisdom.

My defrost timer runs normally when it stops when it reaches the defrost mark. After 2 or 3 hours, I have to manually turn the defrost timer past the defrost mark and the compressor then starts working again. This is a brand new timer. The heater, thermal fuse and defrost sensor are all tested and working. What could be the problem?

If the defrost timer fails how do you jumper it out to keep the freezer working

How to wire outside freezer condenser fan and switches

I liked this video, but it is very confusing at the end.

Excellent!! I'm getting my ass kicked by a 25 year old coil. No schematic, no def term, and unit nor working, fans not blowing.

Timer getting hot

Why wouldn’t you get 0 isn’t the clock just a switch?

N does NOT send power anywhere - as you incorrectly state N is the NEUTRAL - and is the RETURN PATH

Pump down switch is in the wrong place!

This diagram is wrong. Poin N you have connection L and N without load. Spark will hapen and braker off. You have to go learn and learn .

This is the best - detailed schematic explanation I have seen on youtube
