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...

Freezer would not shut down kept running continuously Jd F. • Russellville , AR • October 22, 2014
Suspected it was the thermostat, since temperature stayed the same at multiple settings over a 24 hr period. There was only three components inside the freezer besides the evaporator, the fan was working, so I decided to just go ahead and replace the thermostat and defrost thermostat. Also replaced the defrost timer by the compressor, just to get all the old parts replaced with new. I had already replaced the compressor, so now I've pretty much have a new freezer.

Refrigerator and freezer were warming and cooling Cathleen S. • Lake Forest , IL • October 05, 2014
We just had the Defrost Timer replaced less than 90 days ago. Called the appliance company who came to diagnose ($109) and it was the same part, (a $34 part). The part was warrantied, but not the service, which was $270. I saw them install the part in July... less than 5 minutes! The company told me that they bill not by time spent on labor, but according to the "national average" for that repair. They wouldn't give me the warrantied new part without doing the labor. I checked with...
