FRT21NNHB4 Frigidaire Refrigerator - Instructions

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..

Replace thermostat and show and tell made it easy.

1st. replaced the defrost thermostat pn 5303918214 did not fix it next replaced the defrost timmer pn 215846602 that did not fix it,next replaced the defrost heater pn 5303918247 still did not fix it,has the same problem as when I started I don't know what to do next guess will call for a service tech to come out,or get a new refridgerator. Looks like I wasted my money on these parts. Refridgerators are not as easy to fix as yall make them out to be. I have to say all the parts were easy to install and your instructions and videos were great, they just did not fix my refrigerator Thanks Tom

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.

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!

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

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.

Removed bottom grill, removed two screws on left side and removed timer, unplugged it and plugged in new timer and reinstalled. Less than 10 mins. The Thermostat is in the freezer section behind the back panel. Removed all contents, removed shelving, removed 5 nut screws, and removed panel. Thermostat was clamped to top of coil assembly and was very easy to unplug and remove. New thermostat had a clamp built into it and was very easy to plug in and reinstall to the freezer coil. About 15 mins. This is an easy job for anyone who has any mechanical ability at all.

I remove the covering over the coil and defrost the solid frozen coil with luke warm water which took about 7 min. and replace the thermostat which I knew was bad.Wasn't sure about the timer,so I replace it too @ that price which took about 3 min.Put back and replace everything with clean-up,about another 10 min.

followed the video very esay

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.

inspected visible refrigeration lines for evidence of leaking, found nothing substantial that would cause concern, ordered capacitor and defrost thermostat simply because both are inexpensive parts and theoretically either could be causing the problem. Both parts were very simple to install especially since I am a semi-retired refrigeration man.
