This was a service call on a walk in freezer temping at 20 degrees I found that the systems temperature controller was adjusted too high. I corrected the setting and watched the unit come down to temp.

    Install a Ranco ETC. problem solved. No more walking from vibration. It either works or doesn’t. The Emerson style ETC are also very neat because you can power steal if you are unable to pull another wire.

    You are one of the best technicians I’ve ever seen. I’m 20 yrs old and I interested to learn this job. I want to tell you that your videos are great I will learn a lot with your videos. Thank you so much.

    I bet They got a truck in and they were putting the product away and they turned the thermostat up while they were in there and forgot to turn it back down. Hence why they didn’t want to replace it because they knew they forgot maybe? Just a theory..

    I have a question I hope you have the time to answer. I had a call on a under counter refrigerator where the temperature would get up to 44 degrees then slowly come down to 38 degrees then go back up to 44 or 45 customer said it does not happen to often. I put my gauges on, my low side was at 45-50 my high was 250-300 psi. Evaporator looked ok no ice build up. its like an intermittent problem I wanted to replace thermostat cause I felt that was the issue but it was normal fridge temp which was 39 degrees n defrost clock look ok. My question is did you ever ran in to something like that? If so what was your solution? I'm 2 months into this trade I'm still learning the company I work for just threw me to the wolves. I had this call earlier today n I ordered a thermostat cause I feel that what it was, would love your opinion if you have time thanks.

    Hey Chris I had a question after watching your podcast on refrigeration controls you were talking about TDs and I was always taught coming up this rule of thumb what’s ur take on this , fan forced evaps 15 degree td, gravity coil 20 degrees and cold plates 25 degreee td

    I'll bet you one of the staff adjusted it, because they were salty about something, I've seen it before when I worked at a Tim Horton's, guy was written up for swearing in front of customers, being a right dick, he gotten written up and almost fired, the same morning the freezer which is supposed to be -20c was 10c no actual proof but the dial doesn't move easily

  7. Greg Mercil says:

    Let's say that they wanted to just replace the temperature control, would it be a good idea to mount the new control box to the wall behind the evaporator to keep the thing from vibrating itself to the wrong temp again over time?

    That was a quick one and I liked how you explained the operation. For a newbie that is terrific, got to pound in the theory of operations. If you have that you can theoretically find any problem right? Thx for the great videos.
