Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Can you tell me if there is any Frost on the back panel behind the food in the freezer? Also is the fan running in the freezer?
My first thought was since this is a seemingly erroneous signal tripping the temperature alarm circuit could this be a failure of the control board? I'm not that sure of how to test for such a problem.
This is not my personal freezer but I'm going over to see it again tommorow. I'll let you know what I see.
Any thoughts on the control board? - Thanks
Looks like the problem has been narrowed down to the door switch or the control board. Here's what's going on.
Freezer temperature is correct on the display according to my readings (1 degree). No frost build up on back panel. Fan working fine.
When I put it into diagnostic mode it showed the door open/ajar when door was closed. That part is clear cut and looks like a bad control board or a bad door switch.
My question to you is, does the door light switch communicate this information to the control board or is there some other sensor that does that job?
Can you think of anything I may be missing here? - Thx
