When the heating elements in a residential oven fail to produce heat, the malfunction can stem from several specific mechanical or electrical faults. For electric ovens, common culprits include a completely burned-out bake or broil heating element with a visible break, a tripped thermal overload fuse, a faulty electronic control board relay, or a loose wiring connection at the terminal block. For gas ranges, typical causes include a weak igniter safety valve that fails to draw enough electrical current to open the gas safety valve. You can troubleshoot heating faults safely using a digital multimeter. You can verify that your corrective action is successful when replacing the damaged heating element, fuse, or igniter restores proper thermal baking performance.
