SubZero 533 Freezer Works Intermittently

[JImf2009]

First off ....Anyone have a link to a SubZero 532 Repair and Service Manual?

My freezer stops working on occassion - ruled out the compressor relay, the defrost timer

I pull it apart (take the screen off and front compressor panel and it shoots back to life. Put it all back and freezer turns off in a day or two

cleaned it out pretty well, refrigerator side never has an issue - only freezer. SO will work as long as i dont put the screen on??

Heat build up maybe - would that shut down a thermostat - fan works fine and seems like good airflow ....

any suggestions (other than just live with the top grille not on lol)

Verify if freezer compressor is getting power during the shut down periods. Should be an envelope up there with a decent schematic. If no power trace it back to whatever component is failing.

 

How did you rule out the defrost timer? Most common cause of the trouble you are having.
