GFU20F5AW4 Gibson Freezer - Instructions

We removed the trim and the screws and kept them in a safe place until the handle arrived. It took only about 10 minutes start to finish. Very Easy!

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 fan. I ordered the fan and received it the following.(-:

Unplug freezer let stand all night to defrost. Remove the tray cover which is located on the upper back area inside the freezer.( 3 twist fittings remove it ). Remove the upper stainless steel panel which is secured with 6 screws. This will drop down exposing the condenser. Note all the wires and fan will stay attached to the stainless steel panel, this panel will drop down no need to unplug anything. On the left upper side next to the condenser you will see the thermostat. Two color coded wires. Remove the thermostat and install the new one at the same location.

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.

I first noticed my ice cream getting soft. Then 2 days later the alarm went. I emptied the freezer, opened the panels and saw no frost. I saw that 99% of issues were resolved with a defrost timer and thermostat so I ordered those. I have to say the parts came quickly and they went in very easy. My freezer seems to be in the 1% category though. It's still not cooling even though I can measure the temperature at the front of the evaporator coil is cold but by the end of the coil it's almost room temperature. I think a repairman is called for.

The evaporator fan would make a very high-pitched whine/squealing noise usually after starting up after a defrost cycle, although, it would make the same noises during normal operation. After performing a thorough inspection of the fan blade and motor, I discovered that there was no interference to the rotating fan, and realized the motor must be failing. After removing the food and racks from the main body of the freezer, I had to remove 8 Philips-tipped screws that held the inside back panel cover on. I disconnected the fan motor from the main wiring harness, removed the fan mounting bracket (2 5/16" hex head screws), and then removed the fan motor from the mounting bracket (2 5/16" hex head bolts. I removed the fan blade and conducted a visual inspection, and found not blemishes of broken/damaged pieces. I mounted the new motor and used the existing fan blade, and replaced everything in the reverse order. I turned on the freezer and it has been operating perfectly since. I disassembled the old motor and discovered that the stator coils were worn, and the bearings allowed to much forward/aft motion.

Replace thermostat and show and tell made it easy.

When i found out there was no thread in brace where bolts were supposed to screw in, I panicked. I thought I would have to send part back or go to a machine shop to make a thread. I called a friend for help and he told me the bolts would make the thread if I just screwed them in. Sure enough, the bolts made the thread and then I just proceeded to instal motor and put refrigerator back together. It was simple.

Upluged power pulled freezer out from wall removed the two screws that holds the defrost timer unpluged defrost timer pluged new timer in mounted new timer back with the two screws pluged freezer back in and job was complete. Freezer working fine.

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.

Plugged in the new parts. No tools were required. Sears wanted to charge me $300 for the repair!

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.
