John V Longmont , CO September 09, 2014 Appliance: Model LG GLASSTOP STOVE High temperature thermostat went bad after running self clean function Did some Google searches and most comments concerning this issue on LG stoves indicated the high temperature thermostat malfunctions when using the self cleaning function. This malfunction causes complete loss of power for the entire stove and locks the oven door. Since I wasn't completely sure if it was the thermostat or where it was for that matter, I called a service tech to troubleshoot the stove. He was able to determine it was the thermostat and further tested his findings by connecting the two wires together which were connected to the thermostat (thus bypassing the thermostat) which caused power to be restored to the oven. He told me his magic book indicated the cost to repair would be $175-$350 including the part. He provided the part number (also in the stove parts manual) and I went to AppliancePartsPros.com where the part was $2.75. The tech showed me where the thermostat was located and it took me 1 minute to replace it using only a flat head screwdriver. The tech mentioned it was NOT a good idea for folks to use the self cleaning option because if it doesn't blow the thermostat it may eventually fry the circuit boards behind the stove. Word for the wise....careful using the self cleaning function and clean it yourself ;). Appliance tech service charge $55.00, finding replacement part at AppliancePartsPros.com $2.75, replacing the thermostat myself and saving hundreds of dollars...priceless!! Well not really but way cheaper! Read More... 213 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes Tools: Screwdrivers

Christopher T Larkspur , CO April 02, 2020 Appliance: LG Electric Range LWS3081ST LG error code f 9 Replaced thermostat on rear of oven and that was it. I tested continuity after removal and failed, and also malformed so you could tell was bad. Thermostat on top of unit was good. Recommend buying both when purchasing as found several posts of either failing although the rear was more common - seemed to be different parts but not sure if interchangeable. We used the oven earlier that day at 500 degrees so assume that's what cause was. We've run self clean in the past and may have been contributing factor.
