When the stovetop burners on a residential range operate normally while the main oven cavity fails to produce heat or power on, it indicates that the electrical or gas supply to the appliance is fine, but a component dedicated exclusively to the oven has failed. Because electric ranges utilize a dual-phase 240-volt supply where burners and the oven may rely on different internal circuits, a blown thermal fuse, a broken bake heating element, a faulty electronic control board relay, or a dead igniter will disable the oven while leaving surface burners functional. You can troubleshoot heating components safely. You can verify that your corrective action is successful when replacing the broken bake element or thermal fuse restores reliable heating to the oven cavity.
