Ferdi for Model Number ZET1PM1SS HI We have been experiencing problems with the oven that it does not keep its heat .It will sometimes drop with 10 -50 F and then you will have to set it back to the heat you want it. Could this be a faulty door lock ,temp sensor or something else?? Kind Regards Ferdi
