AFFU1766DW3 Frigidaire Freezer - Instructions

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

it was great. I ordered the capacitor for my frigidaire frig and it arrived
in 3 days. plugged in the part to the compressor and my frig has been
working ever since. I spent 3 minutes ordering the part and 30 seconds
attaching it to the frig. Easy, very easy. saved myself a 75 dollar repair
visit. thanks

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 .

After researching other issues found on internet about same problem, decided to replace both thermostat and temperature control thermastat before going to the repairman way. I saw the videos given on this web site, ordered the parts and when they came in, unplugged freezer and started taking apart the back cover not sure what I would find. Turns out it was just that simple, unplugged the thermastat and unclipped it from the cooling fins, unplugged the temperature control switch and then plugged both units back in. The tricky part was coiling the temperature sensor ( not that tricky). I was done in about 45 minutes but that also included cleaning out and scrubbing the bottom and sides of freezer since I had everything out anyways. Started the freezer back up and took about 8 hours to freeze ice and other food at a setting of 4, where as before I had it set on 7 and was still not keeping the ice cream cold.

Replaced freezer defrost thermostat. Unit worked perfectly.

Ordered freezer key friday afternoon received it saturday afternoon. Fast service

thanks to all of the people who had the same problems I was able to make a quick fix on my fridge. I pulled the back cover off and found the compressor not kicking on so I replaced the start cap. and im back in bussiness.

Took out three shelves. Removed 9 screws with a battery powered drill with a phillip screwdriver bit. Popped off the thermostat like I had seen on the video. Put the new thermostat on. Replaced the two wires one at a time. Reassembled the unit. This was so quick that my wife told me to let her know when I wanted to fix the freezer. She was shocked that I had completed the job. I'd been in the garage less than 10 minutes. It has been six weeks. and the freezer is working perfectly.

The sliding shelf side rail is held by three philips head screws that tighten into nut inserts. No amount of tightening would keep two of the three screws tight. I found that the nut inserts which are plastic and insert into the side of the freezer would pull loose, probably from years of overloading the sliding shelf basket. Ordered two nut inserts from PartSelect. 1. Remove three screws to remove shelf slide side rail. 2. Remove nut inserts to be replaced with needle nose pliers or reinsert screw a couple of turns and pull nut insert out with pliers. 3. Insert new nut inserts, position side rail, and tighten screws. Replace sliding shelf/basket.

I replaced the defrost timer,defrost thermostat,and run cap.as it turned out the compressor went bad. I dont know the model because but the time I got this review I replaced the refer with a knew one . two weeks living out of coolers was so much fun !!!!!!!!

Replaced fan. I ordered the fan and received it the following.(-:

per the video..easy installation....unfortunately the temperature did not improve. We still have a refrigerator temp in the upper freezer.....and a "cooler" in the refrigerator section

I ordered a new thermostat and installed it in less than 15 minutes. Looks like the problem is fixed. Now ,the freezer cycles on and off correctly. The part was ordered on a Monday and I got it the next day. I am very satisfied.

I should have ordered start kit instead of start capacitor. The start cap astir did not fix problem so I ordered kit. Compasator comes as part of kit. Followed enclosed instructions. Cut existing wires and reconnected new wiring. Simple as that. It's a plug in item. Now worried it may be working to good. Freezer down to 10 deg. Watching to see if compressor is running to long. Seems ok lol. Wife hates me now. She wanted new frige.
