Upright frost free freezer would not keep food frozen (Frigidaire name plate but made by (Electrolux) testing determined the refrigeration system worked but it would not defrost. Kenton K. • Chanhassen , MN • May 31, 2020
Fixed it by replacing the electronic control board. Only 30 min. to fix. (See further down for effort to diagnose the problem.) Most of this "fixing time" was spent removing the control panel to access the control board that is attached to it. My freezer has the control panel located in the top center of the door. The only way to remove the control panel is to pry the panel out of the door using a thin-bladed putty knife.The instructions provided were very good in explaining the process;...

No cooling from refrigerator lights worked but compressor did not run Jeff B. • Ovalo , TX • May 07, 2015
Checked compressor windings - ok. Start relay looked no rattle or burning. Start capacitor seamed ok but hard to check. No 120VC to start relay at any time. Ordered thermistor, and electronic control unit. Figuring it was a bad thermistor not telling the ECU it was warm and to turn on the compressor. Or the ECU was damaged and was not sending the 120v to the compressor. Changed the thermistor first (cheapest part and as Appliance parts pros has a return policy I wanted to start there). ...

No lights in refrigerator Lance B. • League City , TX • November 06, 2020
We bought a new house that has a 15 year old GE Monogram built in fridge. The home warranty people sent two guys out saying it was nearly impossible to repair the fridge and they both suggested buying a completely new freezer door for the fridge and of course the warranty company said it was preexisting and we weren't covered. Shocker.
I have lighting in the freezer but not the fridge. I purchased a door switch and replaced the old one but that didn't do the trick. So i purchased a 2 amp fuse...

Not cooling properly eventually evaporator fan failure Richard D. • Wood Ridge , NJ • April 25, 2016
My problem first showed up as varying temperature in both sections of my old mid 1970’s Frigidaire model FPCI-170T-7 refrigerator, which is not listed on most appliance repair databases.
Running on the warm side from time to time, as well as sudden fan noise (probably the fan blade hitting ice build-up on the evaporator coil) alerted me to a possible defrost system problem, since the compressor was cooling. The evaporator fan eventually failed after a day or so, and a major repair was...
