When a residential kitchen oven suddenly stops working and refuses to heat up or power on mid-use, the sudden failure is typically caused by a tripped household circuit breaker due to an electrical overload, a blown internal thermal overload fuse caused by overheating, a snapped bake heating element, or a failed electronic control board relay. You can troubleshoot electrical faults safely using a digital multimeter. You can verify that your corrective action is successful when resetting the circuit breaker, replacing a blown thermal fuse, or swapping a broken heating element restores electrical continuity and allows the oven to heat up properly.
