MFU14F3GW0 Frigidaire Freezer - Instructions

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.

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.

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".

The timer in this older unit is clearly exposed at the back of the freezer underneath the freezer compartment. It is attached with two Phillips head screws. After the screws are removed, the timer can be unplugged and the new one plugged in. The new timer has an extra flange to allow it to be used on more than one model of freezer. In order to mount the timer in this unit, you have to remove the extra flange by carefully cutting it away from the timer body, in similar fashion to what's depicted in the online video. This will allow you to mount the new timer to the mounting plate using the two screws from the old timer.

On 08/13 / 2025 starting in the AM --- My Wife Marie Defrosted -- Cleaned and dried the Kenmore up right freezer she has had for more than 33 years --- She noticed there was screws behind the inside door gasket and informed yours truly --- 1st Jacques loosened all the screws then removed the old gasket -- took it cleaned it and boxed it in the box the new gasket came in --- Took new freezer door gasket and installed it neatly around the door by tucking back part of door gasket between door panel and door --- once all was in place started tightening all screws starting at bottom holding bottom gasket material tight with other hand --- then working counter clock wise till done !!! there you go it was very easy and turned out great !!! Now everything is like new !!! Jacques And Marie / from Virginia

Removed old gasket, then installed new gasket. Make sure to allow new gasket to set out for a few days prior to installing to get all wrinkles out, use a heat gun after installing to make gasket shape to freezer door.

Loosen screws, removed old gasket seal, replace with new gasket (nice to use 2 sets of hands) and re screwed. Used hairdryer to heat up and fluff out a spot that wasnt seal all the way. Pretty simplementation to do.

First unplug freezer, then disconnected wires from timer.
Removed 2 screws from bracket holding time to freezer.
Attached New part with screws. .The mounting bracket is now part of New time. Reattach wires.
I let coils defrost and then plugged it.

Unscrew all the fasteners from the door inner cover from the bottom to top to hold it in position, got rid of the old gasket.

I Cleaned all and install the new gastket into the door inner cover. then reintalled cover to the starting from the top to bottom to hold it in place.

this is a one man job but with two will be easer

No repair. The key fit!

It's easy to know how to use a key. I didn't have a difficult part, I didn't have the model # because I had lost my key and the model # is inside. I was able to find the energy saving paper that came with it but it had four model #'s. I called a couple places and no could me. I pulled up Part Select on line and just thought I would give them a try. I got a very nice person (Jeremy) He went thru every model that I had and three out of the four matched so he sent me a key and if it didn't work I could get my money back. I give him a A+ four taking that extra step, unlike the other places. Very satisfied!
