took the shelves out, unscrewed the rear panel,unpluged the thermistat and uncliped it from the line.Replaced with new thermistat in the reverse order. Before turning the unit back on,allowed the coils to defrost.All of the process was shown in your vidio that I was able to view while ordering the part. Thank you

Removed evaporator cover, unplug 2 wires to thermostat, unclipped it from the coil. Installed new themostat back the same way.

I first replaced the defrost timer about a week prior and it did not correct the problem. I then ordered the thermostat from partselect and within 15 minutes had the part installed. My refridgerator has been running correctly for a couple weeks.

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.

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.

Open the package and placed the glass shelf in the freezer. The order cam in less then 5 days and it was super easy to install. I would definitely recommend this site for parts.

Removed existing part, tested it, found it to be defective. OrderEd a new one and replaced the existing one.

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

The repair itself total time was quick and easy. Since the original fan blade blew apart, it was only a matter of putting the new one on in it's place. This can be done by feeding the blade between the cowling and Condenser coil and applying pressure to get it on the shaft.

If your fan is still on the shaft, simply push it off and extract it the same way. Then place the new one on the shaft.

In my case, since the part would take a couple days to get, and I had food both in the fridge and the freezer, I removed and unplugged the Condenser Fan Motor and the cowling frame and temporarily spliced a small fan I had into the line for the condenser motor. This kept the fridge working long enough to get the replacement part.

Side note. Direction of airflow is towards the Compressor, and draws air across the Condenser coils.

Hope this helps someone. :)

VERY EASY SLIDE OLD ONE OUT AND PUT NEW ONE IT

Removed the inside evaporator coil to do inside solder job, use torch to heat solder joints on the outside drier in order to remove it and install new drier. Soldered Heat exchanger line to drier and 1/4” copper line to compressor. Wrapped with new insulation wrap. Pulled a vacuum on system and then charged with 4.4 ounces of 134a freon. Works like a champ again!

It was very easy ordering from this site and all we did was place the shelves in the freezer

I removed the shelves in the freezer, took out the five 1/4" screws and lifted off the cover. It was a simple matter of using a blow drier to remove all the ice, then unplugging the two wires and unclipping the thermostat from the upper cooling tube. Then clipped the new one on and reconnecting the two wires.

Works great!!!
