FRT21NGJB3 Frigidaire Refrigerator - Instructions

Cleaned insert hole, did a dry-run, then pressed everything permanently in place.

The door shelves in the freezer door of my Frigidaire refrigerator were broken, rendering the shelves useless. I ordered four (4) end caps from PartSelect. The end caps arrived in about five days. I attached the caps to the ends of the door shelves and popped them into the slots on the door. It was a very easy repair!.

Removed broken and installed nw part.

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

It snapped in place.

removed screws with from the back panel of the freezer; located defrost thermostat attached to coil with a metal clip; unplugged thermostat and replaced with the new one. Put every thing back together and it works perfectly.

Slipped out the end caps with the broken prongs from the front rack and slipped in the new end caps. (3 mins.)

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

just like the video showed...it was excellent!!!

took 4 screws out of the discharge vent on top of the refrigerator section and unpluged the wiring harness and put the section on the counter and unscrewed the timer and put the new one in and reinstalled the assembly and plugged the Jack and put the 4 screws back in, and rotated the timer and put it on defrost removed the back and check the heaters and drain .

The instructions given to me by part Select were very good.I replaced the Timer- checked the heater with oham meter it was good- checked the door weather striping it was good and replaced the thermostat with new .So at this point I may need to call a professional unless some one has another solution.

The old drain pan had a 1 ½” tall bushing attached to the center of the pan. The new pan did not have this bushing which was great. I had to cut about 1 inch off the bushing to remove the old pan. Also after cutting the bushing I had to screw the bushing off after cutting the old pan from the bushing. I installed new pan onto the ½” of threads that was left on the top of the compressor. Checked repair two days later all was great.

Thermostat-Thawed freezer, took out drawers and loosened drawer track(back screw)to help remove back panel. Removed five screws from back panel with nut driver and slide panel up and out. Removed thermostat from coils. Two wire connectors pulled apart. Spring loaded connection on coil pulled off. Placed new part from partselect.(reversing sequence) Timer-Took two screws out from behind kickplate at bottom left of freezer. Pulled connector thermostat out of connector. Replaced with new timer. Turned plastic dial on timer until it clicked. Frig turned on, one week ago. Everything appears to be fine.If it doesn't freeze up in the next two weeks, I will start feeling real good.

Unplug the refrigerator. You will ultimately need to remove the back panel of the freezer. But first, you will need to unscrew 2 screws on a small vertical fan vent and unscrew two screws on the fan. Maneuver the fan out of the round hole in the back panel and unplug the 3 prong wire connection. Then remove the fan. Unscrew the 4 remaining visible screwson the back pannel and remove the panel. This will expose the freon coils. On this model, the heater has two connections at the top of the coils. Unplug those wire connections. The heater extends down each side of the coils and along the bottom of the coils. Unhook two aluminum ties that connect the heater element to the coils. These ties stabilize the heater element and also prevents any current from flowing along the element because of the touching of two different metalic parts. Maneuver the heater element out of the coils. To install the new heater, reverse the above process beginning with installing the new heater element. If it hasn't already been done, it is good idea to test the old heater element with an ohm meter to make sure that the element is actually bad. The circuit should be open. This is the second heater element that I had to replace on this refrigerator, and it was actually burned in half both times, so I knew for sure the element was bad. Then test the new element to make sure it is good, and start the installation..

Watched video on Part Select which shows you how to replace the thermostat with several good pointers. Very easily done and now the freezer works great.
