So, right before X-mas this year(2018) our GE Profile PFS22MISBWW started having issues maintaining freezer temp. The wife and I started to look for new Frig but with a kitchen remodel on the distant horizon we weren't very excited about buying a new one that may not fit with the as yet to be designed new kitchen. So, I Googled the issue and watched all of the APP videos that seemed to be relevant and went to work.
First I tested all three thermistors; (1) in the Frig and (2) in the freezer using an OHM meter and a glass of ice water as instructed in an APP video. It was a PITA cuz the wire length for all but the one attached to the evaporator were very short and hard to get into a container of ice water. I didn't get the exact 16.3 k Ohms as the specs indicated but was within the +- 5% at about 15.5 k Ohms on each. My next thought was the mother board, but it looked and smelled good and obvious to me, had been replaced by a prior owner of the frig. Also, the Frig didn't seem to have some of the other bad MB symptoms that I had read about (dimming lights when dispensing water, etc.). So digging deeper, I read the issue might be the Run Capacitor or the P.t.c. + Olp Asm, so I purchased both from APP. Even being just days before X-mas the parts were on my door step in 2 days (Thanks APP!).
I replaced the P.t.c. + Olp Asm first, using the old run capacitor and that seemed to do the trick and was going to call it good. But after reading a bit more into how a bad $39 run capacitor can really jack up a Frig I decided to install the new run capacitor for a little peace of mind.
It's been about a week now and the Frig hasn't missed a beat, but as with all major appliance repairs and uncertainties, my fingers won't be uncrossed for at least another week.
This is not my first time purchasing from APP and me not being a member of the disposable generation and "thinking" I'm somewhat handy, it won't be my last. APP, thanks for all of the resources and having the parts available to fix darn near any appliance!-KC
