MRT21GNCD1 Frigidaire Refrigerator - Instructions

Based on the diagnosis on this site I thought the 66% odds of the problem being the Defrost Timer looked pretty good, $30 including shipping versus a Sears tech phone estimate of $250-300. BINGO! Just follow the online installation instructions and don't forget to use the reset switch as described. Works like new! THANK YOU

Problem not consistent. OK for 2-3 weeks, then freeze coils. Mark and observe the defrost timers manual rotating adjuster. Timer would stop mid cycle. One revolution equals 8 hours of compressor run time followed by 30 minutes of defrost. Replacing timer took 5 minutes.

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

The repair was straightfoward. The evaporator motor I received from partselect was a different model with different wiring configurations. I cut the wires from the new motor per the instructions I received with the new motor and I did the same with the wires that connect to the fridge. Once I matched the wires and secured them with electrical caps I began to put the evaporator motor to the base and started screwing the screws the way I took them off. Once I connected the wire harness to the back of the freezer and turned it on I noticed a big difference in air flow. I was surprised at how easy it was to fix my refrigirator problem. It's been a few weeks now and the fridge is cold and working like it should. Don't be afraid of this task. it's very easy and will save you a ton of money. Thanks partselect.

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.

Removed the timer, installed the new one. Great service from part select

there were three possible problems the timer, the thermostat, or the heating element.i replaced the timer first as that is the problem 65% of the time and that did not fix the problem, i replaced the thermostat and that did fix the problem. after watching the video on line from parts select i took the back off of the freezer from the inside, defrosted the coils with a hair blower and then swapped out the thermostat which pops right off and i spliced the old connectors to the new thermostat. the heat shrink tubing that came with the part was a little to big so i put a smaller peice on each side for water proofing. that is what the cigarette lighter is for to supply heat to the heat shrink tubing.now that i have fixed that problem i may tackle the ice maker next

Removed the lower trim panel from front of fridg. and loosened two screws enough to turn it about 1/4 inch so the screw heads were in the larger holes. Pulled it out disconnected the wire connector and transfered the heat shield and screws to the new clock, connected the wire connector and aligned the screws. tightened them and job done. Has worked like new sense. Thanks Roger

1. Disconnected electrical. 2. Removed upper console in refrigerator by removing 2 nuts. 3. Disconnected wiring from console. 4. Removed 2 screws from defroster timer part and pulled off from connector. 5. Replaced with new defroster timer and put everything back together. Thank you Steve for the U-Tube step by step video.

Simply replaced the defrost timer located inside the frig just behind the temp dial. Very easy job. Removed the 3 screws holding the temp sw and light assembly. Removed the defrost timer w/ 2 screws and put i all back together. 15 mins at most. Suggest you watch the install video for pointers.

per the video..easy installation....unfortunately the temperature did not improve. We still have a refrigerator temp in the upper freezer.....and a "cooler" in the refrigerator section

I watched the video online where it described the troubleshooting tips for this type of symptom. So I knew exactly what the problem was which is the defrost timer. After the part came in I just unscrewed (4 screws) the box which houses the thermostat and the defrost timer from top ceiling of the refrigerator section. Then I just unscrewed and unhooked the old defrost timer and replaced it with the new one. After finishing the installation I turned the fridge on. At first nothing happened. So I turned the dial on the defrost timer with a flathead screw until it clicked and the fridge came alive. I waited for an hour or so. The cooling cycle completed and the fridge stopped as expected. When I opened the door I noticed the interior is much colder than before and right after closing the door the fridge hummed back into life again. So I know my fridge is working again. Thanks to PartSelect for providing the right part for my refrigerator. I will definitely buy from them again if anything goes wrong.

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
