Determining whether a residential oven heating element is broken, burned out, or failing involves performing a visual inspection and an electrical continuity test with a digital multimeter. First, disconnect power to the oven for safety and inspect the metal coil inside the cavity for visible blisters, cracks, holes, or charred break points. Second, remove the mounting screws and pull the element forward to disconnect the wire leads. Third, set your digital multimeter to ohms and touch the probes to the terminals. You can troubleshoot heating circuits safely. You can verify that your heating element is broken when the multimeter displays an infinite resistance reading (OL), indicating an open internal circuit that requires replacing the element.
