FFU20F9GW5 Frigidaire Freezer - Instructions

take 1/4 hex screws out clean out dust ,remove old fan blade replace with new install bolts .

removed screws with from the back panel of the freezer; located defrost thermostat attached to coil with a metal clip; unplugged thermostat and replaced with the new one. Put every thing back together and it works perfectly.

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

Replaced freezer defrost thermostat. Unit worked perfectly.

This was an easy job. First remove the ice maker, if you have one. Mine was mounted with just two screws. Loosen these screws, unplug the power cord at the connector and then lift the ice maker off. Remove the light bulb cover and the light bulb, just so you dont break it. Remove two hex screws and the back cover can be removed. My fan was mounted in the middle of a bracket retained between two rubber bushingings. Just push the fan blad of the shaft and pull the motoer out. Dissonect the power cord at the connector. My moter was differant than the replacement on the mounting so with the removial of the two screws on the motor I was able to exchange the upper and lower cast motoer housings. Reverse the assembly process and you good. Mine is running great.

The important part was the parts delivery. Ordered one afternoon received the next afternoon. Very impressive!!

I ordered a new thermostat and installed it in less than 15 minutes. Looks like the problem is fixed. Now ,the freezer cycles on and off correctly. The part was ordered on a Monday and I got it the next day. I am very satisfied.

just like the video show sa 1,2,3 yeaaa thanks

Replace thermostat and show and tell made it easy.

I followed the You-Tube instructions, removed the ice from the compressor and replaced the thermostat with the part I received from Part Select. What I took out was a part that was very much inferior to the replacement part. The repair saved me a lot of money for a new freezer and it was not difficult to do following the video. Now the freezer runs better and quieter than ever. Thank you Parts Select.

After researching other issues found on internet about same problem, decided to replace both thermostat and temperature control thermastat before going to the repairman way. I saw the videos given on this web site, ordered the parts and when they came in, unplugged freezer and started taking apart the back cover not sure what I would find. Turns out it was just that simple, unplugged the thermastat and unclipped it from the cooling fins, unplugged the temperature control switch and then plugged both units back in. The tricky part was coiling the temperature sensor ( not that tricky). I was done in about 45 minutes but that also included cleaning out and scrubbing the bottom and sides of freezer since I had everything out anyways. Started the freezer back up and took about 8 hours to freeze ice and other food at a setting of 4, where as before I had it set on 7 and was still not keeping the ice cream cold.

Removed bottom cover , just two screws , slid old part through install hole and removed wires from old switch and installed on new switch. Installed new switch in same hole and pushed gently until it locked in place. Reinstalled bottom cover and done.

inserted key and turned

replace thermostat and timer after defrosting and cleaning out freezer. I took less than 10 minutes and now freezer has a defrost cycle that eliminates frost buildup on the coils.
