MRT21NNCD0 Frigidaire Refrigerator - Instructions

I original tried to repair the motor but was not able to. I remove the screws on the back plate and removed the the back plate. Removed the shroud for the motor and screws, unplug the power connection and removed the fan motor. Installed the new fan motor and reassembled everything. The refrigerator is working great.

The temperature was slowing rising in the refrigerator section of a side-by-side. As a precaution, I changed out the defrost timer and defrost thermostat. The parts were not expensive. I then tested the defrost heating element with a multimeter and found the actual culprit was a burned out heater coil. I ordered the part one day and it was delivered by FEDEX the next day. The three parts were much cheaper than a new refrigerator and took little time to install, thanks to the Parts Select website and the how-to-install videos. Now the fridge works great and we saved having to buy a new appliance.

The old drain pan had a 1 ½” tall bushing attached to the center of the pan. The new pan did not have this bushing which was great. I had to cut about 1 inch off the bushing to remove the old pan. Also after cutting the bushing I had to screw the bushing off after cutting the old pan from the bushing. I installed new pan onto the ½” of threads that was left on the top of the compressor. Checked repair two days later all was great.

Unplug the refrigerator. You will ultimately need to remove the back panel of the freezer. But first, you will need to unscrew 2 screws on a small vertical fan vent and unscrew two screws on the fan. Maneuver the fan out of the round hole in the back panel and unplug the 3 prong wire connection. Then remove the fan. Unscrew the 4 remaining visible screwson the back pannel and remove the panel. This will expose the freon coils. On this model, the heater has two connections at the top of the coils. Unplug those wire connections. The heater extends down each side of the coils and along the bottom of the coils. Unhook two aluminum ties that connect the heater element to the coils. These ties stabilize the heater element and also prevents any current from flowing along the element because of the touching of two different metalic parts. Maneuver the heater element out of the coils. To install the new heater, reverse the above process beginning with installing the new heater element. If it hasn't already been done, it is good idea to test the old heater element with an ohm meter to make sure that the element is actually bad. The circuit should be open. This is the second heater element that I had to replace on this refrigerator, and it was actually burned in half both times, so I knew for sure the element was bad. Then test the new element to make sure it is good, and start the installation..

Turned off Refrigerator by thermostat switch in Freezer Compartment,(allowing for light to work in freezer). Then removed all food from freezer side,then all shelves & basket drawer. Next, unplugged refrigerator from electrical source. Removed back of inside of the freezer. Located the Thermostat for defrosting cooling coil. Removed and replaced with new part.(Tip-unplugged the wires for the original thermostat, remove from freezer and cut off and splice with connectors provided with new part, it's easier because you're not trying to do this in the narrow space of the freezer). Then attach the thermostat with new bracket and plug thermostat wires back in, replace back panel, shelves, plug in power supply, turn thermostat switch in Freezer to normal setting. Wait for Freezer to cool and replace food. It's currently working like new. BTW I thought I need a defrost time as well...however after I ordered that part and received it, I turned the existing defroster timer manually with a straight ended screwdriver very slowly and it cycled and the defrost rods glowed/functioned just fine. Therefore I didn't replace defrost timer. I'll save the new timer for future repair if needed. All in all it was fairly easy, and I didn't have to buy another fridge. I was really pleased with the service of this website...and the parts arrived very quickly via Fedex. Thanks www.partselect.com ! KJ

dismantled the top rear panel of the freezer and found I had the wrong part. Hand started the fan motor and it has been working fine since.

first I replaced the timer control hoping thats the problem,unfortunately situation the same ice build up on the freezer.so I replaced the defrost thermostat.right now I'll still observing the condition if still the same.may be in couple days.so far its good.and to replace the parts is not difficult and easy.

Removed screws that fastened bracket to fridge. Next, I replaced the motor and carefully lined the brackets up so the motor would rotate smoothly. Put the fan blade on the motor and screwed the brackets back on the fridge. Motor kept popping out of alignment while I was screwing the brackets back in but I kept snapping it back in till it stayed.

1 went with maj 69% said defrost timer. NO. 2 went with second choice run cap NO. 3 went with my thought, ( PTC Starter ) why not, most exp part. Fixed the problem.

Emptied freezer, removed fan motor cover (2 screws), removed fan and motor (2 screws), removed old motor from bracket and reassembled with new motor, transferred fan blade from old motor to new), re-installed new fan/motor (2 screws) and reinstalled cover...

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

replaced the defrosting timer and saved a lot of $ by doing it my self.

Followed instruction vedeo from partselect. THANKS!!!!!

Took off the old crisper drawer cover supports with the screw driver and put the new ones with the screw driver and small hammer (really easy)thank you to your installation instructions video.
