This defrost thermostat kit is an essential component for maintaining proper temperature regulation in your refrigerator or freezer. Designed to monitor the evaporator coil temperature, it prevents overheating during the defrost cycle by opening the heater circuit when the coil reaches approximately 50°F (10°C). Replacing a faulty thermostat can resolve common issues such as frost buildup, inconsistent cooling, water leaks, or increased energy consumption. Installation is straightforward—follow your appliance’s manual for guidance and ensure the power is disconnected before starting.

Confused
The salesman who helped me identify and order the part was great. However, he said I could find easy instructions on how to replace the part on Youtube. Well, such is not the case. I can find a ton of reports on replacing the part on other fridges, but not a thing on my model, (which is modern). Guess I have to call a repairman after all. CHeers

Frost build up behind "in refrigerator" ice maker. Ice maker mold temperature above 20 degrees inhibiting ice making
Used the following video link to replace thermostat:

Since problem was frost build up on coils behind the ice maker I figured the problem had to be the thermostat or the heater coil. All diagnostic tests on ice maker worked fine. Ordered both...50-50 chance. Turned out to be the thermostat, but replace both. Working good now.

Where does the defrost thermostat go? How far back into the ice maker housing and does that have to come out?
For model number EW23BC71IS8
Hello Ralph, Thank you for your inquiry. It's in the very back of the housing, you should just need to take the shelves and ice bucket out to access it. Although we do not have a repair video for this exact part number, I have included a link to a similar part to assist you. Hope this helps!

Ice maker keeps freezing up and not making ice, would the cause be the defrost thermostat?
For model number FFHB2740PS4
Hello Steve, thank you for reaching out. Make sure the water line is not plugged or damaged. If it is, replace it with part number PS3633241. If that is not the case, we would suggest checking the Water Inlet Valve, part number PS7321353, and Defrost Thermostat, part number PS3493212. We hope this sorts out your problem!
Defrost thermostat 240386402 does this switch just open and close or is there variable resistance as it warms up. I tested it by putting in another freezer and my original one changes resistance as it warms up and does not just open or close. Thanks for any help you can offer.
For model number FPHB2899PF2
Hello Craig, Thank you for the question. A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more. We hope this helps.
