GLFH21F8HWA Frigidaire Freezer - Instructions

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.(-:

Replaced freezer defrost thermostat. Unit worked perfectly.

Removed three screws each side to remove old slides. Needed spacers under new slide so that drawer would stay on track. Cut old slide to make spacers and installed both slides in 15 mins.

Watched video on Part Select which shows you how to replace the thermostat with several good pointers. Very easily done and now the freezer works great.

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.

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.

just like the video show sa 1,2,3 yeaaa thanks

Replace thermostat and show and tell made it easy.

I followed the You-Tube instructions, removed the ice from the compressor and replaced the thermostat with the part I received from Part Select. What I took out was a part that was very much inferior to the replacement part. The repair saved me a lot of money for a new freezer and it was not difficult to do following the video. Now the freezer runs better and quieter than ever. Thank you Parts Select.

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.

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.

Remove the cover panel inside the freezer, remove and replace the fan motor (pull fan blades off old motor and push on the new one) and replace the cover.
