MFU20F3GW9 Frigidaire Freezer - Instructions

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

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.

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.

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.

I order another one thanks

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.

took door of removed gasket replaced

Removed shelves ,removed panel on interior back wall with Philips screwdriver ,unplugged wire terminals slid thermostat off coil ,then reversed process to complete installation.

The old defrost timer started making a screeching noise (probably bearings going out). The replacement part was a cinch to install. When I initially spoke to a PartsSelect person, they said the part number I gave them was not consistent with my old '94 Tappan Freezer. They were able to still find the proper replacement part number. The video that was on-line helpful also.

Replaced thermostat and it fixed the problem. Freezer comes on and turns off automatically and regulates internal temperature around 2-5 degrees.
The hardest part was extending the coiled probe tubing and forming it to fit into clamp without kinking it.

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

Followed the instructions

After removing the key from its shipping package I pushed it into the freezer locking slot and turned it to lock and unlock the lid and then removed it. I had no problems with this fix. Of course, I am an older gentleman with a lot of experience in repairs around my house,as well as other houses. I am sure that a less experienced person may have more of problem with this type of "repair".

Freezer was not running, I reset circuit breaker and it immediately tripped. Noticed smoke coming from behind freezer. I pulled freezer away from the wall and visually checked the compressor and a black plastic box connected to the compressor (later found out the box is called a controller) I pulled the controller off the compressor and saw that it was burnt and melted. I ordered a controller from you, not knowing if that was the problem, but I took the $50.00 chance (cost of controller) I removed the old controller from the wires by sliding a small screwdriver along a slot in the plastic next to the wire and it released the wire, I did the same to the other wire and reconnected the wires to the new controller, observing what color went to what connector on the controller. Then I plugged the controller onto the compressor and reset the circuit breaker and plugged the freezer in bingo, it started right up and has been running now for over a week.

I changed the cooling control
