MRT21NSHW2 Frigidaire Refrigerator - Instructions

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.

Thermostat-Thawed freezer, took out drawers and loosened drawer track(back screw)to help remove back panel. Removed five screws from back panel with nut driver and slide panel up and out. Removed thermostat from coils. Two wire connectors pulled apart. Spring loaded connection on coil pulled off. Placed new part from partselect.(reversing sequence) Timer-Took two screws out from behind kickplate at bottom left of freezer. Pulled connector thermostat out of connector. Replaced with new timer. Turned plastic dial on timer until it clicked. Frig turned on, one week ago. Everything appears to be fine.If it doesn't freeze up in the next two weeks, I will start feeling real good.

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 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..

1st. replaced the defrost thermostat pn 5303918214 did not fix it next replaced the defrost timmer pn 215846602 that did not fix it,next replaced the defrost heater pn 5303918247 still did not fix it,has the same problem as when I started I don't know what to do next guess will call for a service tech to come out,or get a new refridgerator. Looks like I wasted my money on these parts. Refridgerators are not as easy to fix as yall make them out to be. I have to say all the parts were easy to install and your instructions and videos were great, they just did not fix my refrigerator Thanks Tom

Replaced freezer defrost thermostat. Unit worked perfectly.

I watched the video you had on-line and it was simple. Thank you so much

bottom left cornerof fridge defrost timer replaced two bolts and a wire

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.

I'm not knowledgeable on Refrigerators or A/Cs, so when our Frigidaire stop working,I told my wife that there was nothing I could do to fix it. We had friends that had a spare in their garage so we offered them $500.The only thing wrong it was the ice maker. When looking at the manual and parts I came across this site and didn't realize that the air went through the freezer first. After putting my model number in,it showed the common problems with that fridge, then I watched the videos and realized how simple it really was.I Just had to remove the freezer panel in the back to replace the thermostat and the defroster was easily at the bottom front to the left corner, it cost me about $46 and about 30 minutes of my time. I'm a handyman and I do almost all my repair work and almost gave this fridge away. I can't thank this website enough. Yes, we spent $500 on another fridge but, it was one that my wife was wanting anyway. Thanks again

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.

Ordered the new part-Unplugged the refrigerator - took off the cover over the defective timer - put in the new part put the cover back on - plugged the refrigerator back in - so far, so good!~

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

remove back metal cover inside refrigerator,disconnect the blower motor ,install new motor,use existing motor bracket and blades. now my refrigerator runs perfect !!!
