MRT21NSGD2 Frigidaire Refrigerator - Instructions

I went on partselect put in make and model number, a list showed the probable cause. I watched the how to video. When I received the part in short order I loosened 2 screws disconnected the wiring plug (sprayed it with contact cleaner) pluged it in, removed screws from old part put them in new one. Put timer back in its location and tightened the screws. Very eazy, works fine.

I pick up very fast at these kind of small jobs but because of my very busy schedule I decided to call (2 times) technicians about my problem but none of them had any idea. About my repair, I removed the grill at the bottom of the refrigerator, unscrew a small plate (located on the bottom left side) that's holding the defrost timer. I plug on the new part, screw back the plate with the defrost timer and that was it. Don't forget to turn clockwise with your finger the timer until you hear a "click" and then turn it slightly more to the right. There is also a video on U-tube.

followed the video very esay

I am a 65 year old woman with no mechanical aptitude: I just unplugged the frig. And used a screw driver to pry of the plastic socket from its outside edge. . Then you just unplug two tiny contact plugs that appear when you pull out the socket and replug in those two the same way on the new part. Pop the socket back into the hole . . . . And screw in the new bulb. I knew I needed the socket part cause when the bulb burned out , a new bulb still did not work. . . If I can do it, anyone can!

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.

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 !!!

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

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

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.
