When a residential kitchen oven powers on, illuminates its digital control panel, and runs its timer or cooling fans normally but fails to produce any heat inside the cavity, the malfunction is typically caused by a burned-out bake heating element, a failed gas igniter on gas ranges, a blown thermal overload fuse, or a malfunctioning electronic control relay. If an electric heating element has an internal break or crack, electrical current cannot flow through the coil to generate thermal energy. You can troubleshoot heating failures safely using a digital multimeter set to continuity. You can verify that your corrective action is successful when replacing a broken heating element or a faulty gas igniter restores normal thermal output and brings the oven up to your selected cooking temperature.
