Oven Not Heating

Bake or broil that never comes up to temperature

An oven that stays cold — or preheats for an hour and still will not brown food — is a common kitchen call from San Francisco flats to Daly City and Peninsula homes. Gas ovens may click without ignition; electric ovens may show a preheat bar that never finishes. Bake can fail while broil still glows, or both elements/burners stay dead. Heat faults mix control, igniter, element, and sensor issues. Gas and 240-volt electric ovens are not safe DIY projects.

Bay Appliance Repair diagnoses oven not-heating calls Monday through Friday, 8:00 AM to 5:00 PM from 140 San Pedro Rd, Daly City, CA 94014 (Bay Appliance Repair). Service calls only. Call 415-585-5900 or email service@bayappliancerepair.com. California BEAR #46247.

Common causes (high level)

Electric wall ovens and ranges often lose bake from an open bake element, a weak broil element used for preheat assist, a failed oven sensor, or a control that never closes the bake relay. Gas ovens typically spark or glow at the igniter without opening the gas valve when the igniter is too weak — a very common weekday finding. Thermal fuses, door-lock switches on self-clean models, and tripped double-pole breakers also take heat away while lights and clocks still work.

  • Open or blistered bake/broil element (electric)
  • Weak igniter that will not open the gas valve (gas — pro only)
  • Failed oven temperature sensor or control board
  • Door lock or self-clean switch interrupting bake
  • Tripped 240V breaker, loose range cord, or gas shutoff not fully open
  • Ignition module, safety valve, or wiring faults (gas — pro only)

Range and cooktop surface burners are a related but separate path on our stove pages. This guide is for cavity heat: bake, convection bake, and broil that never arrive.

Safe checks — and what not to DIY

Stay with external, unpowered observations. Gas valves, igniters, 240V elements, and hidden terminal blocks belong to a licensed technician:

  • Confirm the oven is not in Sabbath, demo, or a locked self-clean cool-down that blocks bake.
  • Note whether the clock and interior light work; a dark display plus no heat can be a supply issue.
  • For electric ranges, verify both sides of a double-pole breaker are on — do not open the back panel or probe live terminals.
  • For gas ranges, confirm the gas shutoff behind the range is fully open; do not dismantle gas fittings or “test” with an open flame.
  • Look through the glass (door closed) for any glow at bake or broil during a preheat attempt; write down error codes.

Call a pro — do not DIY: replacing gas igniters, opening sealed burner boxes, jumping safety valves, testing live 240V bake circuits, or bypassing thermal fuses. Fire, shock, and carbon monoxide risks are real. If you smell gas, shut the range off, leave the area if needed, and contact your gas utility / a qualified technician — do not keep trying ignition.

When to call for oven repair

Book service when the oven never reaches set temperature, food is raw after a full preheat time, you smell gas or scorching insulation, error codes repeat, or only broil or only bake works. Weekday same-day appointments are often available by route. We do not advertise overnight coverage.

San Francisco scheduling: San Francisco oven repair. Regional hub: oven repair Bay Area. Surface-burner problems belong with stove/range repair; microwave cavity heat is a different appliance.

What diagnosis looks like

We confirm fuel type, test the heat path that matches gas or electric, and explain repair versus replace without pressure. Many no-heat ovens return to service with an igniter, element, sensor, or control-related repair when the cavity and door seals are sound. No fabricated EPA claims or fake review widgets — licensed weekday work under BEAR #46247.
