MFU20F3GW0 Frigidaire Freezer - Instructions

Pulled out the freezer. Unplugged. No freezer back cover was there. The compressor start relay was in a plastic encasement attached to the compressor - wires led me to it. Removed the solid metal spring with a screwdriver and removed the plastic cover. Tried to pull out the defective relay but the freezer was so old I needed a pliers to remove it. When I put pressure on the old relay with the pliers the relay broke and came off in pieces. I then removed the wires from the broken parts and put them on the new relay. I pushed the new relay onto the 2 pins then replaced the cover and spring. After plugging the freezer in the problem was fixed.

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.

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".

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.

I removed the compressor start relay and replaced it with the new part. Initially it did not work. When I checked my work, I had to tighten the connector on the new part. Once I made the correction, the freezer is freezing normally again.

Had to lossen around 60 screws to allow for the old gasket to be removed. Then I began the process of inserting the new gasket by fitting it into the gasket channel opened when I loosened the 60 screws. I inserted the gasket a little at a time making sure it was properly fitted then I tightened that part and then do the next part until I finished replacing the gasket.

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.

No repair. The key fit!

Purchased gasket from parts plus installed it and door still won’t stay shut without duct tape plus the frost is building up really bad looking for another parts store to get problem fixed

Brought replacement key works just like original I thought it would be metal from reviews but it was plastic and still works perfectly

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!

Oh yea thanx to partselect it went great didnt get fisrtkey but when got the second key it worked great thanx partselect

Notice ice build up on the panel in front of the evaporator coil. Unplugged freezer and removed evaporator panel. Plugged unit back in and checked fan, coil "snap switch" and heater element, all seemed to check out good. Found defrost timer stuck in the freeze position, causing frost to accumulate over the evaporator. Manually rotated defrost timer to the 30min defrost cycle and system went into defrost. Ordered defrost timer and installed (part arrived in 3 days). Freezer works great again. Too bad I ended up throwing 400 dollars worth of meat away. the fix was very simple. Will definitely use PartSelect again. Thank you.

take 1/4 hex screws out clean out dust ,remove old fan blade replace with new install bolts .
