My oven won't heat — what do I do?

An oven that won't come up to temperature splits cleanly by fuel type: on electric ovens it's almost always the bake element, and on gas ovens it's almost always the igniter. Both are common, affordable repairs. Here's how to tell what you're dealing with, and the safe checks first.

⚠ Safety first: For GAS ovens, do not attempt igniter or gas-valve work yourself — call a technician. For electric ovens, cut power at the breaker before inspecting anything.

The most likely causes

Bake element (electric ovens) Moderate DIY check

The bottom heating element is the most common electric-oven failure. A failed element often has a visible blister, break, or burn spot and won't glow.

Check it: Look at the element with the oven cool: a visible break or burn mark is a strong sign. Replacement is a straightforward repair.

Oven igniter (gas ovens) Technician

The igniter both lights the gas and tells the valve to open. As it weakens with age it glows but no longer gets hot enough to open the valve — so the oven doesn't heat. This is the #1 gas-oven failure.

Check it: You may see the igniter glow but no flame. Do not DIY gas parts — this is a technician repair for safety.

Temperature sensor Technician

The oven's temperature sensor tells the control how hot it is. A failed sensor can cause no-heat or wildly wrong temperatures.

Check it: Not a DIY check. Diagnosed by a technician.

Control board or thermal fuse Technician

A failed control board or a tripped thermal fuse can cut power to the heat circuit.

Check it: Not DIY. A technician confirms and replaces.

Wrong mode or lock Easy DIY check

Delay-start, Sabbath mode, or a self-clean lock can make an oven seem dead.

Check it: Confirm the oven isn't in a delay, lock, or self-clean cycle before assuming a failure.

Is it worth fixing?

A bake element or a gas igniter is an affordable part and a quick repair — an oven that won't heat is well worth fixing in nearly every case. Replacement only makes sense on a very old range with multiple failing systems.

Common questions

Why won't my electric oven heat up?

On an electric oven the usual culprit is a failed bake element — often with a visible blister or break. A bad temperature sensor or control board is possible but less common. The bake element is an affordable, common repair.

My gas oven igniter glows but there's no flame — why?

That's the classic sign of a weak igniter. As it ages it still glows but can no longer get hot enough to open the gas valve, so the oven never heats. The igniter needs replacing — and because it's gas, it should be done by a technician.

Is an oven that won't heat worth repairing?

Usually yes. The two most common causes — an electric bake element or a gas igniter — are inexpensive parts with quick labor.
