AFFU1766DW3 Frigidaire Freezer - Instructions

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.

We were looking for a new freezer --thinking it wouldn't be worth calling a repairman. I was trying to determine the size of the freezer and couldn't find it in the manual. So I googled the model number and stumbled upon this site. Thought it would be worth a try and $12 plus shipping to replace the thermostat. Got the thermostat a couple days later, followed the video directions to replace it--not hard! Plugged it in and it is working great!!! SOOOOO glad I stumbled on your site! You saved us $700-$800!! Thank you! Thank you! Thank you!

removed screws with from the back panel of the freezer; located defrost thermostat attached to coil with a metal clip; unplugged thermostat and replaced with the new one. Put every thing back together and it works perfectly.

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

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

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

I watched the videos (they really help) and followed the steps. Everything went smooth with no surprises

Replaced freezer defrost thermostat. Unit worked perfectly.

When i found out there was no thread in brace where bolts were supposed to screw in, I panicked. I thought I would have to send part back or go to a machine shop to make a thread. I called a friend for help and he told me the bolts would make the thread if I just screwed them in. Sure enough, the bolts made the thread and then I just proceeded to instal motor and put refrigerator back together. It was simple.

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 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.

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 !!!!!!!!

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.

pulled out freezer, went to floor,reached in next to compressor pulled off clip just like on the video.Pulled off old capacitator took off wire leads.Installed new one. Freezer runs great.Loaded it up with beef pork and venison. No problems.

i order the defrost timer and the temperaturecontrol as was advised,it was very simple as reading the previous notes, pulled knob off, rerout temp metal probe, while the cover was off i clean it as much as i could and repainted the bottom with applince paint, looks good as new, very easy, whent to the defrost timer was so simple unscreewbracket, pull wire clip harness replace harness rescreew bracket, replug freezer it's good as new, saved a lot of money, i love this web site
