Oven Not Heating — Causes & Parts

Oven Not Heating

An oven that runs but never actually heats is one of the most common range complaints, and it almost always narrows to one of a small handful of parts once you separate electric ranges from gas ranges. On an electric range the heating happens in a bake element you can usually see inside the oven cavity; on a gas range the same job is done by a burner igniter and a gas valve you generally cannot see without removing the oven bottom panel.

Before assuming a part has failed, confirm the basics: the oven display is lit and responding to button presses, the breaker for the range has not tripped, and -- on a gas range -- the gas supply valve behind the unit is fully open. Once those check out, the cause is almost always inside the heating circuit itself, not the electronics that control it.

A useful first triage step is watching exactly what happens when you start a bake cycle: on an electric range, look through the oven window for the bake element to glow within the first couple of minutes; on a gas range, listen for the igniter clicking or humming and watch briefly whether it glows at all. If the element glows but the oven still runs cold, or the igniter glows but never opens the valve, that observation alone points you straight at the right cause below instead of guessing.

Most Likely Causes

Work through these from most to least common -- most range and oven repairs turn out to be one of the first two or three parts on this list, not the last.

1. Bake element burned out (electric ranges) — the element at the bottom of the oven cavity develops a visible blister, split, or hole, and may spark or glow unevenly when powered. Part type: Frigidaire Range Bake Element 316075103 (316075103).
2. Igniter too weak or cracked (gas ranges) — a healthy igniter glows bright orange-white and draws enough current in about 30-90 seconds to open the oven's gas valve; a weak one glows dull orange, takes far longer, or never opens the valve at all. Part type: Frigidaire Range Oven Burner Igniter 5303935066 (5303935066) or Tappan Range Oven Burner Igniter 316489403 (316489403).
3. Oven temperature sensor or probe reading incorrectly — the oven appears to run a full cycle but never reaches the set temperature, or the burner/element cycles on and off erratically because the board is getting a bad signal. Part type: Frigidaire Range Oven Temperature Sensor 316490000 (316490000), Range Oven Temperature Sensor (318562500), or Oven Probe (316233900).
4. Safety thermostat tripped or failed open — this thermostat is a protective cutoff -- when it fails it can cut power to the entire heating circuit even though the element or igniter is fine. Part type: Range Safety Thermostat (3196548) or Wall Oven Safety Thermostat (WB24T10060).
5. Oven selector switch or control board failure — least common. If the element/igniter, sensor, and safety thermostat all test normal, the switch or board that routes power to the heating circuit is the remaining suspect. Part type: Oven Switch (316021500); also inspect the Terminal Block (5303935061) for burnt or loose connections.

How to Confirm Before You Buy a Part

Before ordering any replacement part, take a minute to confirm the fit -- it is the difference between a repair that works the first time and a part that does not match.

1. Find the model/serial plate. On most ranges it is behind the storage drawer or kick panel at the bottom front, inside the oven door frame, or on the back panel of the unit. See how to find your model number for exact locations by appliance type.
2. Read the full model number exactly as printed, including letters and dashes -- manufacturers often reuse near-identical model numbers across different production runs that take different parts.
3. Verify the part fits that exact model using the model and part lookup tool before ordering, rather than assuming a part fits because it looks the same as the one you are replacing.

The full model number matters more than the brand and body style alone: one range body design is often sold under many model numbers over several years, with the exact igniter, element, switch, or control board changing partway through that run. Two ranges that look identical side by side can still take different parts if their model numbers differ, even by a single trailing letter or digit.

When to Call a Licensed Technician

Most of the parts above are within reach of a confident DIY repair using basic hand tools and a multimeter. Two situations are the exception. First, anything that requires opening a sealed gas valve, running a new gas line, or repairing a suspected gas leak is technician-only work -- these repairs need pressure testing and code-compliant fittings that are not a basic-tool job, and a mistake here is a safety hazard, not just a wasted part. Second, if you have already replaced the most likely part from the list above and the symptom persists, or a fault code keeps returning after a full power reset, a licensed technician with brand-specific diagnostic tools can usually isolate the remaining possibilities faster than continuing to swap parts by trial and error.

Check Your Exact Model

Part numbers above cover common range and oven platforms, but the only way to be certain a part fits your range is to look it up by model number with the model and part lookup tool. A few real range models with parts already indexed:
