GFU20F5AW3 Gibson Freezer - Instructions

I knew from a problem years ago that the Thermostat was the likely cause so I ordered a new part and replaced it. Only need a phillips head screwdriver to remove the part and add the new one..

I first replaced the defrost timer about a week prior and it did not correct the problem. I then ordered the thermostat from partselect and within 15 minutes had the part installed. My refridgerator has been running correctly for a couple weeks.

I replaced the timer and the defrost thermostat. The defrost thermostat replacement was almost exactly like the training video here. The old part attached slightly differently. The most time consuming part was thawing out the heat exchanger, which was completely covered with ice, inside and out.

Compared to the training video, the timer took more work given its location. It was low to the ground and a bit difficult to get at around the other wires and parts. However, the new part fit perfectly. I just unplugged and unscrewed the old part then reversed those steps with the new one.

Removed the old defrost timer by removing 4 screws on the holding bracket. Disconnected the wire harness. Reconnected the wire harness to the new part. Installed the new part with 2 screws on the top of the molded bracket. I am a 67 year old woman... easy-peasy. (the defost timer is located in the bottom left rear of the freezer.

I followed the video. It’s not that it’s a bit difficult, it’s just going slowly and carefully.
The thing that I didn’t allow the 24 hours for the gasket to relax after leaving the box. Also, I forgot to heat the gasket and put a small layer of Vaseline.
So the next day I noticed the the gasket wasn’t seating properly and went back to the video and carefully followed the steps to gently heat it with a hair dryer and Vaseline. The gentle heat let the gasket properly relax and seat. The Vaseline helped created a small vacuum to complete the gaskets “training” to seal properly.
24 hours later it was beautiful and the freezer was working like new.
Parts Select was great to deal with.

Best way is to watch the video on YouTube and follow the directions

First I removed the clamp, pulled out the part, and diconnected the two wires on the side and a small screw. Reconnected the new part with the small screw, connected the wires and plugged the part back to the side of the motor. Whaa La, Done.

Bought the defrost timer based on PartSelect recommendations, installed it and no change. Apparently the old one was fine but since the refrigerator was in a flood and this part got submerged in water I kept it rather than returning it. I looked at everything closely and realized all the mechanical functions were working properly. Rarely does a condenser coil fail so I decided to look into recharging the coolant. Bought a 1/4 inch bullet valve, a 12oz. can of R-134a and a cheap resealable can adapter with hose, gauge and R22 to R-134a adapters. After a $30. investment Bingo, after one squirt the refrigerator began to cool and after 4oz. it now works better than new. I understand that PartSelect is in the business of selling only their parts but please consider that there can be other simple problems.

I order another one thanks

1. I took out one screw on the ice maker and loosened the other two screws and unplugged and removed the ice maker.
2. Next I took out 2 screws from the bottom of the auger drive box and unplugged the wiring harness and removed the box. The wiring harness was a little tricky. The lock on the plug pushes in to unlock even though it looks like it pulls out,.
3.next you must remove 2 screws from the left side bracket that holds the auger box and remove the bracket.
4.Now take out 8 screws that hold the back panel in place and remove the back panel.
5. now your looking at the evaporator fan blade and motor. The simple way to replace the fan blade is to unplug the motor and remove it from the freezer. It just sits in with nothing holding it. The fan requires a little pressure but should pull right off. Install new fan blade and put everything back in the same order it was removed.

From discussions with friends, I determined the problem might be easy to fix. The fridge made a lot of noise, but the compressor DID come on, and inside the freezer was cold, but the main fridge was warming.

After unplugging the fridge, I removed the fan assembly in the freezer (there were about 4 nuts and a couple of plugs to uncouple.

I could see right away the fan blades has broken off, but the motor looked good. The new new fan pushed easily onto the shift and fit perfectly in the housing.

I reinstalled the fan assembly, plugged in the fridge, and right away heard the new fan come on - very quietly. What was a roar became a whisper and the fridge was down to 38 degrees with a few hours.

Parts Select included a video, and I watched a couple more that were on YouTube. Watch the video and do the repair . . . it's very easy took me about 35 min once I got the freezer emptied, including cleaning the freezer. I used a Philips head screw driver and I think it was a 5/16 nut driver . . . you can do this. Freezer running fine, no noise. One thing I would be careful on is removing the back plate that covers the fan and motor, the edges can be sharp and you could cut yourself removing the back plate. Also don't try to put the rubber gasket in before you replace the back plate, install the back plate and the rubber gasket goes in easy peasy :)

Took longer to take out the shelves and the 10 screws holding the cover on then to replace the fan.
Local parts supply told me it would take two weeks to get the fan mator,ordered it from parts select and had in a couple days.

Removed existing part, tested it, found it to be defective. OrderEd a new one and replaced the existing one.
