GFU20F5AW7 Gibson Freezer - Instructions

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!

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

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.

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

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.

per the video..easy installation....unfortunately the temperature did not improve. We still have a refrigerator temp in the upper freezer.....and a "cooler" in the refrigerator section

replaced controller start capacitor as per troubleshooting checklist. Was not the problem, then replace controller kit. seems to have resolved the problem.Temperature more constant. The problem with this refrig though in my opinion is that only one thermostat controls both the freezer compartment evap fan in freezercompartment also blows cold air into refrigcomp. There is not very much control over both temps. Am in monitoring both compartments and hoping that freezer will keep things frozen

I should have ordered start kit instead of start capacitor. The start cap astir did not fix problem so I ordered kit. Compasator comes as part of kit. Followed enclosed instructions. Cut existing wires and reconnected new wiring. Simple as that. It's a plug in item. Now worried it may be working to good. Freezer down to 10 deg. Watching to see if compressor is running to long. Seems ok lol. Wife hates me now. She wanted new frige.

Replaced freezer defrost thermostat. Unit worked perfectly.

Remove the cover panel inside the freezer, remove and replace the fan motor (pull fan blades off old motor and push on the new one) and replace the cover.

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.

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.

The handle for the freezer arrived the next day. Most of the time repairs at home are alway a challenge. But the handle was placed where it belonged in about 5 minutes.It was the easiest repair we ever had and now we don't have problemes opening the freezer. Thanks so much.
