I have a GE Profile PSC25PSTA that showed high temperatures (6 and 48 instead of 0 and 37) when we got back from vacation. We moved all the food out but then the next day it was at 0/37 again so we put food back in. Then it went up again, and then the next day it was back down again. Over the last week it seems to be either at perfect 0/37, or back up high around 7/50. Somehow it seems to be cycling into a too warm period, but then recovering.

Any suggestions gratefully received, thank you!

If you dont have a lot of frost buildup on the back inside wall of the freezer, then you prob need a new main board. Main Control Board--Part Number AP3957581. http://www.appliancepartspros.com/ge-kit-main-brd-wr49x10152-ap3957581.html

Thanks for the quick reply. I forgot to mention that the freezer is actually swinging back down below 0, going as far as -3 (I might have seen -4 too). I wondered if this might be thermistor and defrost cycle related? Lots of people seem to have replaced thermistors with these units so I was suspicious of that. But I didn't hear anyone describing the same symptoms of rising and falling temps, in fridge and freezer.

I'll check for ice build up in the freezer too.

Have a RTD chart for the NTC's? Also, what usually goes wrong with the pcbs?  :thanks: :thanks:

Take a look at the thermistors. If the seal is black epoxy they may be waterlogged. Replace them.

Thanks. I believe there are many thermistors in this unit... Any suggestion as to which one to suspect?

Right now I have turned off the unit (unplugged it) and left the doors wide open for 24 hours. I'm tempted just to plug it back in again and turn it all back on again now. But the power-off, power-on technique may only really work for electronics and not fridge/freezers!
