2. Safety Valve
If your Bosch gas oven still doesn’t heat after replacing the igniter, the safety valve is the next component to check. The safety valve sends gas to the igniter. If the safety valve fails, the igniter won’t receive any gas to ignite. Contact a technician to test the safety valve and replace it.
3. Damaged Wires
If neither the igniter or safety valve is faulty, you should inspect the wires next. Inspect the wires connected to the terminals of the igniter and safety valve. If you notice that the wires are burnt or damaged in any way, they should be fixed. Contact a technician to fix the wires.
4. Control Board
The control board is the final possible reason why your Bosch gas oven won’t heat. The control board sends voltage to each component in the oven in order for them to function. If the control board fails, it won’t send voltage to the oven components. Before replacing this component, make sure to test every other component above. If they aren’t faulty, read the “Bosch Electric Oven Not Heating” section above to replace the control board in your Bosch oven.
