Do-It-Yourself Stories from Customers like You Freezer cold/fridge warm all vent passages frozen solid water in fridge & condenser fan motor not working   L. H. • Cartersville , VA • July 08, 2016

Replaced: condenser fan motor, defrost timer, defrost thermostat (bi-metal), and added a heat probe. Fan motor obviously shot... hard to turn by hand.

Total repair took slightly over 1 hour. Would have taken longer had I not already have taken the freezer apart on a previous occasion. Therefore I already knew the sequence and was able to disassemble it quickly. A little tricky getting the part out but easier to get it in. SImple repair for anyone mechanically inclined. Read more

Do-It-Yourself Stories from Customers like You This was for a friend of mine his refrigerator stopped cooling   Gary G. • Ofallon , MO • July 12, 2015

This was a 2000 model so rather than just replace the defrost timer which was visibly burnt on the terminals, we just did everything. The cold control, defrost timer, thermostat, defrost heater and the compressor capacitor were all replaced. I had the same issue on my older unit and tore it apart replacing one item at a time over a three month period so on an older one i suggest do it all while it is apart. Read more

Do-It-Yourself Stories from Customers like You The icemaker not making ice.   David S. • Lawrenceville , GA • July 17, 2021

Got the infamous icemaker freezing up problem so common to Frigidaire Gallery and Professional series refrigerators.

So, I went ahead and replaced both of them, as well as installed the updated air handler housing kit. What I didn't realize from the parts pictures was that the air handler kit was not only updated foam replacements, but it was also a... Read more

Replaced the defrost timer. It was not located where the parts explode suggested in the thermostat control box which is located in the upper right corner of the liner.
