When the surface burners on a kitchen range operate normally while the main oven cavity fails to heat up or turn on, it indicates that the power or gas supply to the appliance is functional, but a component dedicated exclusively to the oven circuit has failed. Because electric and gas ranges utilize internal wiring where surface burners and the oven rely on separate controls, a broken bake heating element, a failed oven igniter, a blown thermal overload fuse, or a dead control board relay will disable the oven while leaving surface burners operational. You can troubleshoot heating components safely. You can verify that your corrective action is successful when replacing the damaged bake element or thermal fuse restores reliable heating to the oven.
