Robin S Mullica Hill , NJ January 17, 2021 There was no error code, but the oven would either not heat up or the oven display would say a higher temp than the actual temperature. I bought the appropriate thermister replacement for our oven model. The fix was pretty easy. The hardest part was that we had to pull out the oven to get to the back. We had to take off the back panel to release the thermostat connector. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
