FFU17F9GW4 Frigidaire Freezer - Instructions

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

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!

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.

Removed 2 screws holding front bottom vent grille. . Through opening behind grille found broken part of switch hanging on wires. Removed wires from switch and fed them out through hole for mounting switch, connected wire and pushed into place. The greatest difficulty encountered was my 82 year old knees.

Followed the sites instructions. Empty the bottom part of the freezer. Remove the screws. Move the panel out of the way. Easily remove the old part and replace with the new. Put the panel and screws back in place. The freezer works.

Removed three screws each side to remove old slides. Needed spacers under new slide so that drawer would stay on track. Cut old slide to make spacers and installed both slides in 15 mins.

Watched video on Part Select which shows you how to replace the thermostat with several good pointers. Very easily done and now the freezer works great.

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.

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.

Replace thermostat and show and tell made it easy.
