AFFU1766DW4 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.

I did watch a repair a utube video which I asked for when ordering. Pretty much followed most of the directions but:

started in left corner an lossed all screws from left to right. took off old gasket in small sections and inserted the new gasket and semi tighten screws

proceeded down left side then right little by little as above. to get to bottom of door.

bottom corners were a little snug to get them into place. the last corner was snug but once connected. tighten screws not too tight. You dont want to strip them.

test door with piece of paper.

if paper is not a snug tug, you can adjust gasket with a hair dryer set to low.

it was easy. freezer is all set.

Partselect was great to deal with, support verified the part number was correct for my freezer and help with that video.

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.

I removed the screws and replace the broken slide with the new slide. Put the basket drawer back on the track and it now stays in place and can easily be used once again.

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

Both end caps were missing on the door side bottom metal shelf. succesfully installed no tools needed

easy change less than 10 min

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".

removed old broken part, 3 screws, then installed new part.....done

Pretty simple, take cover off back of freezer to access thermostat, unhook thermostat and replace with new one. It had wire hookups different from original part so had to look up that information. Turned out it did not matter which wire went on which prong.
