Hey everyone,
I'm trying to fix a Turbo Air M3F47-2 freezer.
Problem:
The freezer turns on and cools down to like -10°F. Once it gets near that temp, it then starts climbing up to room temp and never seems to start cooling again.
What I have tried:
I have tried replacing the main board, the D-sensor and F-sensor. I also went and looked and even when its at its coolest temp, I don't see any ice buildup.
A technician told me they suspected there was a problem with the defrost cycle and it was probably the board. That's why I replaced the board. Another person said the probes go bad, so I replaced the D and F.
Does anyone have any other ideas what could be causing this behavior? I am at the end of my experience level here. It's like once it gets to -10°F, it stops cooling and never starts again.
Thanks!
