This authentic OEM high-limit thermostat, also known as a limit switch or cooling fan thermostat, serves as a safety feature to prevent the oven from overheating. It monitors the temperature inside the oven and activates the cooling fan when the temperature exceeds a certain limit. The cooling fan helps dissipate heat and maintain a safe temperature. The high-limit thermostat is usually situated inside the top panel. If the high-limit thermostat is broken or faulty, the cooling fan may fail to turn on, leading to excessive heat buildup inside the oven. You might also notice that your food cooks unevenly since the oven struggles to maintain the desired temperature. In some cases, if the high-limit thermostat is completely non-functional, the oven may not heat up at all. You can test the sensor at room temperature by measuring the resistance between the two prongs at the end of the sensor connector. The resistance should read approximately 1080 - 1090 ohms at room temperature. To access the thermostat, refer to your user guide for detailed instructions. Generally, you need to ensure the power is disconnected at the breaker, lift the top panel on its hinges, remove the screws on the plate under the burners, take out the burners and plate, disconnect the wires from the old thermostat, and remove the mounting screws to release it. Please note that the replacement part is sold separately from the cooling fan.

Thermostat for oven cook elements. Cooling fan is a misnomer-the fan still worked!

First of all I am not Betty, I am her husband. Second I and a friend pulled the range out of the countertop (which was not necessary). The top can be raised on it hinges and the plate under the burners can be removed by taking out 8 to 19 screws and there is the thermostat looking at you. After doing this once and knowing where the thermostat is, the job could be done in less that an hour.. INSTRUCTIONS: Turn OFF the circuit breaker. Remove the burners. Remove the plate under the burners. Change the thermostat (making sure to place in correct direction as the one removed). Reassemble, turn on circuit breaker, test oven heat. Read more...

Thermostat bad....but couldn't fix it

My grandfather who is well versed as an electrician checked my microwave out because it wasn't worked. He used a multimeter to check electric current to parts in the microwave. He said a specific thermostat was not getting any current going through. I ordered that replacement part from this site and when it came in it didn't have current running through it either. He said he thought the part that was given to me was faulty. I called this companies number to ask some questions but the machine said they aren't taking any inquiry calls because of the pandemic right now. So I currently don't know what the problem is with my microwave. I want to return the part but unfortunately during Christmas time the packaging got thrown away. So as of right now I'm out the part money and probably money to buy a new appliance. Read more...
