Product Description

Defrost Thermostat Specifications

This defrost thermostat is also known as a refrigerator defrost bi-metal thermostat kit. The function of the defrost bi-metal thermostat is to prevent overheating during the defrost cycle in your refrigerator by protecting the evaporator. The most common sign that there is a problem with your refrigerator defrost thermostat kit is if your freezer is cold but your refrigerator is warm. If your evaporator coils are icy then your defrost bi-metal thermostat kit could be defective. To do this installation the tools you will need include a 1/4 inch nut driver, a pair of wire strippers and crimpers, and a heat gun.

No heat gun. What about a propane torch? (defrost thermostat)
For model number FRT21KS5AQ1
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.

How do you test defrost thermostat
For model number GLRT183TDW8
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!

My fridge and freezer are running warm. I checked the evap. And compressor fan. I cleaned the coils and i checked the thermostat in the fridge. All these things check out. My last thing to check is the defrost thermostat. However, when i remove the panel in the freezer there is no ice build up. Is it possible that it is still defective but in a way that makes it turn on too often?
For model number LFTR1814LW8
Hello TJ, Thank you for your inquiry. Yes it can, and you should also check the defrost heater and timer as well. Hope this helps!

Where is the defrost timer located my freezer and refrigerator area are warm, i unplugged it for a day and plunged it back in and the freezer got do to 0 deg. The unit sits in a garage around 45 degrees. Do not know if it is the timer or the defrost thermostat?
For model number FFTR1814LW9
Hi Dale, Thank you for your question. The defrost timer is locacted in the control box where the light switch and air diffuser are. If the refrigerator and the freezer are too warm, there are some parts that you will need to check to see which one is causing the issue. You will need to check the defrost timer, the door gasket, the run capacitor, the condenser fan motor, the temperature control thermostat, the starter-ptc, and the defrost timer. I hope this helps. Thank you and have a great day!

My refrigerator intermittently goes off and on. I replaced the thermostat control and when it failed again a few months later, i replaced the defrost timer. It's worked fine again for 3 months and it went off for a couple of hours yesterday and then back on again by itself. What parts would fail intermittently and what do you recommend that i do.
For model number Electrolux/Frigidaire refrigerator P/N 24516600. Model # FRT 18 IS 6CW? (the last number was rubbed
Hello Georgia, thank you for inquiring. This could be due to a faulty Run Capacitor or Compressor Start Relay, but the model number you provided in partial with multiple variations using some different parts. We will need the rest of the model number to determine which parts list to use. There should be one last number or letter after the FRT18IS6CW that you have provided. We look forward to hearing back from you!

Water is leaking on the inside of the fridge and staying on the top shelf where it freezes. I don't know where it is coming from.
For model number FRT17G5CSBO
Hello Denny, thank you for your question. We would recommend checking the drain tube at the back of the freezer to be sure it isn't clogged. The back wall would have to be removed and inspected. You might want to check that area for any excess frost or ice buildup which could be caused by a bad thermostat, heater or evaporator motor. I hope this helps!

Hi, i was wondering how long the freezer compressor should continue running before it stops and the defrost heater comes on. I think i read around 8 hours somewhere. My freezer coils start to ice up long before that. Also, how long will the defrost cycle last?Thanks!
For model number FRT17G4BWD
Good Day Jeff. Thank you for your question in regards to your unit (Model Number FRT17G4BWD). Based on our research the defrost cycle should take approximately 20 to 30 minutes. When it comes to the freezer compressor, our research into this suggests that it should run 45 minutes per hour. Hope this helps. Best Regards.

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...

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.

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.

Freezer seemed ok, though frosty, but the bottom section was not cold enough, and the compressor seemed to run constantly.
The lower compartment was hovering around 50 degrees. Logic told me that cold air was not being driven from the freezer to the lower compartment. At first, I found the passageway between freezer and lower compartment was blocked with frost/ice, which could have been the entire problem. But why was that ice accumulated there? After defrosting, the problem was only partly solved. A few how-to videos suggested that the defrost timer was a common problem, so I tried that, the part was about $11, with minimal improvement. So I concluded that the fan was not driving cold air from the freezer to the lower section. I tested the fan by removing the freezer back panel completely, wiring the fan to an old ordinary power cord, and plugging that in to a wall outlet. The fan would not start on its own, would only turn if I gave it a spin, and then was very weak - I could stop it with a finger without pain! When my new fan arrived, I again removed the back panel in the freezer and replaced the fan, just a few screws to remove, then swap the fan blade to the new fan motor. The process was simple and obvious. Now the lower section stays near 40 degrees, though I'm not convinced that's the only problem-there seems to be a lot of variation in the temperature. BTW, I had also confirmed the defrost heating element was functional by activating the defrost timer (see youtube), to eliminate that from the diagnosis.
