When an electric stove burner or oven is powered on and indicator lights illuminate but the heating element fails to produce any warmth, the malfunction is typically caused by a burned-out heating element, a faulty infinite switch that fails to send 240-volt power, loose terminal connections underneath the cooktop, or a tripped double-pole circuit breaker. When an internal wire breaks or a switch fails, electrical current cannot reach the coil to generate heat. You can troubleshoot heating failures safely using a digital multimeter set to voltage or continuity. You can verify that your corrective action is successful when tightening loose wiring connections, resetting the circuit breaker, or replacing a faulty infinite switch or heating element restores normal thermal output and heats the burner.
