Just replaced all wiring and infinite switches the day before thanksgiving because 2 burners were out. Everything worked fine on thanksgiving. had oven on for several hours. Also used a several times since than. Earlier in the week while using the oven it would NOT turn off. All other buttons on the control panel work fine except when you press the off button. There is no beep or reaction. Breaker has to be shut off in order to do so. Am I correct in assuming that the entire membrane switch will have to be replaced in order to fix this issue? I believe it was already replaced once under warranty. Anything to check for?
