2. Wires

If your Siemens oven is not heating but the element isn’t faulty, the wires should be checked next. Uninstall the oven from the cabinet and take off the rear access panel. Closely inspect the wires connected to the terminals of the heating element for burns or cuts. Any burns or cuts on the wires could prevent the oven from heating. If the wires are damaged in any way, contact a technician to test or replace them. However, if the wires aren’t damaged, keep reading to learn the other reasons why your Siemens oven is not heating.

3. Control Board

A faulty control board is the final possible reason why your Siemens oven is not heating. The control board sends voltage to the heating element in the oven. When the heating element receives the voltage, it turns on and starts to heat. If the control board fails, it won’t send voltage to the heating element. If your Siemens oven is not heating but the components above aren’t faulty, read the “Siemens Oven Element” article above to learn how to replace the control board.
