FFU20FC4CW0 Frigidaire Freezer - Instructions

Notice ice build up on the panel in front of the evaporator coil. Unplugged freezer and removed evaporator panel. Plugged unit back in and checked fan, coil "snap switch" and heater element, all seemed to check out good. Found defrost timer stuck in the freeze position, causing frost to accumulate over the evaporator. Manually rotated defrost timer to the 30min defrost cycle and system went into defrost. Ordered defrost timer and installed (part arrived in 3 days). Freezer works great again. Too bad I ended up throwing 400 dollars worth of meat away. the fix was very simple. Will definitely use PartSelect again. Thank you.

We were looking for a new freezer --thinking it wouldn't be worth calling a repairman. I was trying to determine the size of the freezer and couldn't find it in the manual. So I googled the model number and stumbled upon this site. Thought it would be worth a try and $12 plus shipping to replace the thermostat. Got the thermostat a couple days later, followed the video directions to replace it--not hard! Plugged it in and it is working great!!! SOOOOO glad I stumbled on your site! You saved us $700-$800!! Thank you! Thank you! Thank you!

I had no problems. Screws arrived sooner than expected. It was a very simple installation. Very pleased with both the product and service.

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

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!

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.

We really didn t need to do a repair, we just ordered a freezer key that we didn t have. I must say the shipping was fast we received it the next day. It was worth the shipping charge. We will be ordering again. Great service.

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.

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.

Replaced freezer defrost thermostat. Unit worked perfectly.

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.

Fan was locked up.

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.
