MRT21PNBW2 Frigidaire Refrigerator - Instructions

Unplug the refrigerator. Removed the right hand top shelf. Used a 1/4" nutdriver to remove rear center mounting screw for Control Housing. Used Phillips screwdriver to remove two mounting screws for timer. Unplug cable from timer and plug it into the new timer. Install the new timer and re-install the Control Housing. Plug in the refrigerator and adjust the timer to start the unit. This was a snap with the diagnostic provided by Part Select. At first I thought it was the fan rubbing but when I removed the cover (two screws) it was obvious that wasn't the problem. The diagnostic hinted that it was either the timer or the motor capacitor making the noise. Because the noise continued after turning OFF the control, I thought it was the timer...I was right.

Followed the instruction video. Removed the old one. Attached the fan blade, ground wire and connected power plug. Reinstalled with 2 screws. Works great.

change the evaporator fan motor kit working perfect

After reading other posts, I decided to change the defrost thermostat, so I watched the videos, and did that. It got better, but the problem persisted, and the ice was still building up in the freezer section. So I decided that the problem was with the defrost heater. I ordered a new one, that was here under 24hs (using the Fedex ground). I replaced it, measured the old one and saw that it was not passing any current at all (so it was really burnt). Now the fridge is good as new, maintaining the proper temperatures both at Freezer and Fridge sections. Thank you Parts Select ! With $ 70 in parts I was able to get back my appliance working !!!

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

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

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.

followed the video very esay

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.

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

After some troubleshooting to ensure the thermostat and heating element were working, determined that the defrost timer was the problem. With the defective part, I was able to manually advance the timer to activate the defrost cycle, but it wouldn't do so on its own. Unplugged the refrigerator from the wall. Timer is located in the refrigerator compartment at the very top. The compartment houses the cooling thermostat, the light bulb and the defrost timer. Using 1/4" nut driver, remove 4 screws holding compartment cover to top of fridge. Lower a bit to access electrical wiring. Wiring harness can be unplugged to work on the timer away from the fridge which makes it a bit easier. Timer is mounted with 2 phillips head screws. Remove screws and unplug timer from wiring. Install new timer, plug in wiring, secure with the phillips head screws and remount entire compartment.

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.
