MRT21NRED3 Frigidaire Refrigerator - Instructions

I followed the procedure online and found the thermostat was ok, it had continuity when cold, and the heater coil was also ok, it too had continuity, therefore the problem was a bad defrost timer. the refrigerator works great, thanks parts select!

When I was moving the refrig. handles from one side to the other...I broke one of the mounts. It was SO easy to order from this place, and they ship IMMEDIATELY. Second time I have used them, and am VERY impressed.

Diagnosis: used wiring diagram attached to frig and determined cause could be wiring, heater element, thermostat or timer. After completely defrosting the frig (turned it off) I removed the rear cover in the freezer and looked for an obvious problem. None seen. Removed temperature select pod from the frig box and looked for obvious problems. None seen but defrost timer appeared poorly made. Repair: Since I had no practical way of checking the defrost cycle in operation, I checked probable failures on the Part Select website and saw defrost timer as most probable. I ordered the timer. Installed it. Waited a few days to make sure the frig went through a few defrost cycles then removed the freezer rear cover. There was no excessive frost buildup so I'm reasonably sure the repair was successful.

I replaced the defrost timer,defrost thermostat,and run cap.as it turned out the compressor went bad. I dont know the model because but the time I got this review I replaced the refer with a knew one . two weeks living out of coolers was so much fun !!!!!!!!

Watched the video once. Removed four 1/4 inch screws with a nut driver unplugged the unit, took out two screws securing the timer. Replaced did all of this in about 10 minutes. It was "exactly" as the video showed and it's worked perfectly since the replacement of the faulty timer. I saved a $75.00 service call minimum and the part was more than likely cheaper from Part Select than from the repair facility. Although I'm a pretty good handy man, you would not need any experience to make this repair. The instructions are precise and the part fit perfectly.

tested the thermostat, cleaned the coils, checked seals all clean. defrost timer did not cycle so replaced it but issue not resolved. even though freezer was working while refrigerator was problematic, proceeded to open freezer panel. discovered that fan was not pushing cold air into refrigerator compartment due to ice build up in connecting tubes. cleaned ice and replaced panels to positive result

simply watched videos provided…making it EXTREMELY simple..saved me hundreds by not having to throw it out!! running better than ever like as if it was brand new!!

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

unplugged frig,removed bottom front cover and loosend 2 screws at bottom front left and slid defrost timer out from behind metal panel,unplugged the old and plugged in the new.frig works great.

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 !!!

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.

Instructions from partselect were very clear and probable cause made it easy to narrow things down. I have the manual for the refrigerator that shows the location of the defrost timer. Very surprised that it turned out to be a cheap and easy fix.

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

thanks to all of the people who had the same problems I was able to make a quick fix on my fridge. I pulled the back cover off and found the compressor not kicking on so I replaced the start cap. and im back in bussiness.
