Wall ovens from trusted brands such as Bosch provide years of use, but over time, even the best oven can suddenly go cold. If your wall oven doesn't heat, fix it by following these common troubleshooting tips.
When electric ovens don't heat, the heating element is a common culprit. Most models have a heating element on the bottom that operates during the bake cycle and an additional heating element on top for the broiler. If the broiler still works, the main heating element is probably faulty. Check the heating element for blisters and cracks, or test it with a voltage meter after first turning off the circuit breaker. If the heating element shows sign of breakage or doesn't carry a current, replace it by following the wall oven repair instructions provided by Sears PartsDirect.
On gas ovens, the igniter helps make heat by quickly reaching white-hot temperatures, which triggers the safety valve to release gas. Of all wall oven parts, the igniter is the most common cause for cold ovens. Locate the igniter underneath the bottom panel. If the part has cracks or only glows a dull red, this indicates that it's broken or isn't getting hot enough and needs replacement.
The control thermostat regulates the temperature of the oven. If the oven burner fails to turn on, a broken thermostat may be the cause, especially if your oven has recently also been running too hot or not hot enough. Poor calibration can cause a faulty thermostat, but replacement is still recommended. Sears PartsDirect carries thermostats in their selection of Bosch repair parts.
