Hi, when the oven is set to bake at 350 the temperature will swing from 327 to 417 or more. There doesn't seem to be any temp consistency at any pre-set temp. Is this the temp sensor or control board?
You will want to check the temp sensor for resistance. At room temperature the sensor should be 1090 ohms. If outside of 10% of this then the sensor is bad and would need to be replaced. If this checks ok then the oven control board is faulty and would need to be replaced.
oven will not heat up. i replaced oven sencor and still dont work. the heating element is not geting any power to it.
Answer Larry, the thermal fuse is a good place to start, if it is "open" it will interrupt power to the broil element, and create a low temperature issue in the oven. At the oven control / ERC you may need to test voltage out to the elements Con. 2in 7 red wire to chassis ground should read 120 VAC in a bake mode. Con2 pin I blue wire should have 120 VAC to chassis ground in the broil mode. Both red wires on con 4 should read 120 VAC to chassis ground. Be careful with the voltage checks, don't hurt or shock yourself. if all the voltages are present and correct the ERC is not the issue and the thermal fuse and wiring will need to be checked and replaced or repaired.
