Question:

No heat gun. What about a propane torch? (defrost thermostat)

jack for model number FRT21KS5AQ1
Answer:

Hi Jack, thank you for the interesting question. A heat gun would be the safest route to shrink wrap your wires together. However you can also use a hair dryer, if a heat gun is unavailable to you. I hope this helps.

Question:

How do you test defrost thermostat

Frank for model number GLRT183TDW8
Answer:

Hi Frank, Thank you for the question, The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the thermostat should read approximately 6.2K Ohms at 68°F. With the thermostat submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

Evaporator coil kept freezing up, refridgerator warm.

This was the second part I tried. The defrost timer was first, but that did not fix it. To do this I had to remove the ice maker and the back plate of the freezer. Then I defrosted the coil and cut the wires. stripped them back and installed the new thermostat. re-assembled and tested. has been working great ever since.

Freezer cold, not defrosting, refrigerator not cold

This was extremely easy. Took off the control box (housing that covers the light bulb, has the temp control dial on it) and easily replaced the defrost timer. Then, emptied freezer, took off cover at the back of the freezer. Disconnected old defrost thermostat, attached new one, reattached back cover, melted accumulated ice, put stuff back in. Started up. Been running great ever since. No more ice accumulation in freezer. Temp stays constant. Great service from PartSelect, saved lots of money. This job is easy on this fridge, go for it!

Freezer cold. Fridge too warm.

Ice build up to back of freezer. Fridge way too warm for preserving food/drinks. Unplugged fridge and de-thaw freezer with a hair dryer. Removed and replaced defrost timer in the fridge area which simply unscrews and plugs in. The video supplied by PartSelect worked well for this.

The Defrost Thermostat required a bit more work as it is accessed through the freezer compartment. I had to remove two screws to get the back cover that houses the fan removed. Then you cut the wires from the old Thermostat and remove it before splicing in the new Defrost Thermostat using the supplied crimps and matching the wire colors. It is useful to have a good wire stripper/crimper ready to make the job simple (I bought a pro one for $28 at Home Depot but they can be found cheaper). Also, there is a bit of heat shrink material included to protect the wires from moisture so a heat-gun will do the trick or Good quality electricians tape will also cut it.

I then sparked it up and it works as new. :)

Freezer cold, fridge warm

My evaporator fan was not working. This fan is located in the freezer section, (top), behind an access panel at the rear. Part of it's job is to blow cold air down into the fridge. At first I wasn't sure if it was the fan itself because after the fridge was unplugged an plugged back in, the fan would run for about 5 seconds then quit. So..I tested the auto defrost timer by manually cycling it with a screw driver, it was fine. I bypassed the defrost thermostat switch, no difference. Finally, I cut an old extension cord and connected it to the fan, it was the culprit.. It didn't run on 120. It did spin for a few seconds on initial power up only. After reading that this model may also have a flakey defrost thermostat switch, I ordered both the fan & new defrost thermostat switch. It was a very easy install for both items. No directions are needed, it's obvious when you get in there. Mine is runnng like a champ again.

Refrigerator wouldn't defrost

First, I replaced the defrost timer, really easy, 4 screws popped the cover of the electronic area (top of refrigerator compartment) took it out and plugged in the new time. Unit still would not defrost, so replaced the thermostat as well. Bit harder, removed ice maker, 2 screws, back plate from freezer, 4 screws. Thermostat was clamped to a copper tube- the original had one of the wires hanging out of it- cut the wires and crimped the new wires on, shrunk the plastic tube with blow dryer over the wires (taped them for good measure) and so far so good. Learned most of this through these tips, so keep reading if this isn't your problem, just save myself $1000 on a new refrifgerator...

Refridgerator not cooling n freezer iceing up.

This fridge is less than 2 years old really disappointed with frigidaire quality. Had a appliance repair guy diagnose the problem and paid $45 for the service call but decline for him to do the repair for $320. Remove the cover 4 screws holding it on top of fridge the defrost timer is inside 2 screws and you just unplug and replace with a new one. The defrost thermostat is in the freezer compartment, remove the ice maker if equiped then remove back cover, cut out the old thermostat n crimp in the new one. So far the fridge is working but still not getting as cold as before but good enough to keep things safe. Thanks to partselect.com i saved a bunch of money doing it myself.

Freezer freezing up and blocking the vent for refrigerator, not cooling the fridge.

Went pretty straight forward, except the heat shrink tubing was about 2 sizes too big. Would not shrink small enough to seal the connections. Even with a heat gun it would not shrink small enough. OH, another think is when I plugged the fridge back in the defrost timer was in defrost mode. Took me a few minutes to figure that out and use a screwdriver to turn the timer back to the on position. Other than that, install was pretty simple.

Top freezer working properly, but lower fridge not cooling.

since I had my fridge since 2003 it seems that I've gotten my moneys worth but it has worked flawlessly with no issues. I did not want to part with it so I troubled shoot the system and realized that it could have been number of things so I just decided after reading some reviews here on this site I decided to just purchase the items that would be effecting the fridge not working properly which was the evaporator fan, defrost thermostat, defrost timer, temperature cold control thermostat, I also cleaned the condenser coils in the back of the unit so they can be able to withdraw heat from the unit. my repair and installation took about 4 hours due to the cleaning of the coils but now the fridge is working like brand new. thanks to this sitt and it's comprehensive video tutorials on installations and repair it my job a lot easier to do.this is not my first time ordering from this site and will not be my last. anyone considering ordering from this site do not hesitate there are great with parts and customer service.

Refrigerator and freezer running to warm.

I watched the video on how to change the defrost thermostat. I removed the back cover inside the freezer then I pulled off the old defrost thermostat and then using a pair of wire cutters I cut it off and then bared a little of both of the wires and then slid the heat sherink and wire connectors on the existing wires and then slid the other ends of the wires into the wire connectors then crimped the ends of the connectors and then tried using heat on the heat shrinks but still used rubber electric tape over it. I clipped the new thermostat were the old one was and then reattached the freezer wall cover and plugged the refrigerator back in. 24 hours later I checked the temperature in the refrigerator and freezer and both are running a lot colder.

Freezer worked, refrigerator didn't. Ice build up on coils.

Unplugged refrigerator. Emptied freezer and removed ice maker and cover, need to unplug fan. Defrosted coils with hot water. Cut wires to thermostat as close to it ad possible to leave extra wire in case of an error. Stripped wire in new thermostat and put in shrink plastic then the wire crimp connector joining both light blue wires making sure wires were in before crimping them. Repeated with other dark blue wire. After used the heat gun to shrink the protective white tubing. The only thing i found not satisfying was tge tubing. It was too wide and too small. When i shrunk it did not cover the whole connector and was loose. I had to use a glue gun to cover both ends of each wire connector. Hope this helps other users.
