The oven does not keep temp. The selector switch works fine. If you select 200 degrees on the thermostat it stays on and does not shut off at the temp. setting and had temp. reading of 500 deg.
Sounds like thermostat right? So I replace thermostat and still doing same thing. 160.00 no return for the thermo stat. So maybe someone befor me replace thermostat and did not wire it correctly. Any wire diagrams out there. Thanks
