MRS20HNGD0 Frigidaire Refrigerator - Instructions

I secured the power to the fridge. I took the metal panel which covers the cooling coils in the freezer off by removing the the 6 sheet metal screws. I used a standard hair dryer to melt the ice block which had formed due to the failure of the defrost timer. I replace the defrost timer, which was located behind the left front wheel of the unit. Finding the timer was the hardest part of the job. Since I was having trouble with the defrost cycle I also decided to replace the defrost thermostat due to its age. The most important item I would like to share is once all the work is done and the panel is back in the freezer, the power is restored take a straight slot screw driver and give the defrost timer about an eighth of a turn clockwise to ensure it starts. Then mark it with a sharpe and check it in 3 or 4 hours to make sure it is running. I did not do this on the one I installed and the freezer did not go into the defrost cycle. Once I got the timer started, well the ice cream stay frozen. BE SURE NOT TO WORK ON YOUR EQUIPMENT WITH IT PLUGGED INTO POWER SOURCE!!!

Removed the old fan--three small nuts and snap off connection. Ordered part and received the next day. Your company is great!!

Unplug fan and remove 3 bolts. I had to bend the fan frame in order to remove fan. Change fan blade and reverse procedure. Fridge is fixed nice and cold

The site offers a video for this part which worked perfectly. In addition to replacing the part, since the cardboard panel was off, we also cleaned all the dust off of the coils which someone recommended to do annually.

I put the refrigerator and saw that the fan wasn't working so I change the fan and the problem still the same. I order a timer and thermostat and change them, nothing change so I order the capacitor and when I remove it I saw that the relay swith was burn out so I order a switch and evarything is ok.
The problem when the fan broke the compressor overheat and burn the swich.
I learn a lot and still saving money over these repair guy.

Thanks

Twisted replacement bulb into place easily. Let there be light!

I replaced the bulb using my hands to twist the bulb in the socket located at the top of the refrigerator.

Wasn't sure if it was the derost timer or the heating element. Since the timer was much cheaper, I bought it and crossed my fingers.
My story is like the others. Unplug the refrigerator, snip the old wires, strip back the wire insulation, use the supplied connectors to attach the new defrost timer to the existing wiring.
Success! My coils no longer freeze up.
Only difficulty is I am a large guy, and fitting my upper body into the freezer was challenging.

Removed old thermostat and replaced. really easy.

After posting the specific symptoms and getting feedback, I had narrowed the cause to two linked parts. I ordered both intending to replace first one, then the other as needed. With parts in hand, I pulled off the freezer control knob, used a nut driver to remove the two panel securing screws (behind the face, against the inner ceiling) and gently dropped the cover down. The control (temp sensor and cold control) is easily accessible as it sits wedged into two slots in the plastic cover. The control must be slightly lifted in order to extract the long sensor that attaches to the control and runs under it and into a plastic sleeve behind the panel (the new control comes with the sensor wrapped in a tight coil and it must be unwound for the install). Removed the three wires noting which color goes where. Used needle-nose pliers to remove the small push-on tabs and removed the control. After starting the new sensor probe into the sleeve re-attached the 3 wires to the new control. Used the original as a model for how to pre-bend the probe for the first 2 inches as it was mildly frustrating to position the unit back correctly. Pushed everything back into place, re-installed the screws and plugged the fridge back in...(you DID unplug it first, right?). Still haven't used the second part (defrost timer), but I expect it to go soon...it is a 17 year old refrigerator, after all.

First I remove the back panel which had 4 screws. Then I removed the ice maker. The icemaker is held in place by the 2 screws that requires backing the screws out just a litter, than lift up and remove the electrical connector. Used a volt ohm meter to check the resisitant in the heater element and the defrost timing switch. Both tested good and that left only the thermostat. Removed and replaced the thermastat swich. I cut the ends of the old switch and crimp the ends of wire with the crimps that came with the swict i purchased from parts select. My refrigerator is working properly and making ice like normal.

The defrost timer is located under the freezer side behind the lower plastic cover. Very simple, just 2 screws and a plug, and your done.

The thermostat requires removing the lower drawers in the freezer and unscrew the back side of the rails and let them hang over to get access to the lower cover on the back of the freezer. Once the panel is off you will be able to see the thermostat. From there you just remove the thermostat from the clip, cut the 2 wires, splice in the new thermostat and re install using the new clip and your done!!

This was my first time and it was really simple. I had a local repair shop quote me $375.00 . I did it myself for under 50.00 shipped to my door..

tested defrost timer and heater. And then tested defrost timer with ohm test($6 at hard ware store) Closed and would not open replace and tested freezer take 30mins to get switch cold and retest.

First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the wiring harness plug, replaced the old timer with the new one, re-connected the wiring harness and reinstalled the mount in position. Hardest thing about it was lying on the floor.

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.
