Bosch Oven: not lighting
What is this symptom?
If your Bosch oven is not lighting, you may notice that the gas burner fails to ignite, leaving your oven unable to produce heat. This issue can stem from common problems like a faulty igniter or a closed gas valve, preventing your oven from functioning correctly.
Possible Causes
Faulty igniter (gas models)
How to Identify: When the oven is turned on, the igniter does not glow or glows dimly and the gas never lights; no flame appears.
Part: Igniter / hot surface igniter
Lack of gas supply or closed gas valve
How to Identify: Gas valve may be turned off; other gas appliances in the home may also not light; no hissing of gas.
Part: Gas supply / shut‑off valve

Check the oven control board for any visible damage or burnt components. If necessary, replace the control board. Ensure the oven is disconnected from power before proceeding.
