MRT21NRED3 Frigidaire Refrigerator - Instructions

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.

followed the video very esay

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.

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.

I should have ordered start kit instead of start capacitor. The start cap astir did not fix problem so I ordered kit. Compasator comes as part of kit. Followed enclosed instructions. Cut existing wires and reconnected new wiring. Simple as that. It's a plug in item. Now worried it may be working to good. Freezer down to 10 deg. Watching to see if compressor is running to long. Seems ok lol. Wife hates me now. She wanted new frige.

pulled out freezer, went to floor,reached in next to compressor pulled off clip just like on the video.Pulled off old capacitator took off wire leads.Installed new one. Freezer runs great.Loaded it up with beef pork and venison. No problems.

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

pulled down the thermostat cover and unpluged the timer control and replaced it with the new part. total time to repair was about 15 min. there was a vidio on how to replace the new part that just informed me that I did it right!!!!very easy site to find what you are looking for!!!!

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

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.

Just followed the online instruction video .It was very easy.

You guys at Partselect are the best!!! Went to your site, typed in my appliance symptoms, and received possible fixes. Ordered the suggested parts (under $50) on a Sunday night and got em Tuesday am. Installed the easiest one first and Voila!!!! Frig is working great. Thanks Bob S

Remove 4 screws that hold up overhead controls, this is also the part that holds the light. Unplug the timer and replace. Super simple and runs great now. After you plug it in it may take a few minutes to kick on the compressor but it will. Also I was pleased it was a factory Frigidare part. Price was right.

Unplugged the frig. Removed temp control module from frig, 1 screw with nut driver. Activated defrost timer by rotating adjustment until 2 clicks are heard. Removed two timer mounting screws, unpluged timer, plugged in the new timer, mounted it to the control module with 2 mounting screws. Replaced control module with the 1 mounting screw. Closed door and plugged it up.
