The good news about a non-heating oven is that the cause is usually mechanical, not electrical — meaning it's fixable without replacing the whole appliance. Whether you have a gas range or an electric oven, the failure points are well-known and the parts are widely available. The real question is which component failed, and that depends on whether you have gas or electric.

Electric Oven Not Heating: What's Most Likely Wrong

Failed Bake Element

The bake element is the coiled heating rod at the bottom of an electric oven cavity. It's the workhorse of every baking cycle, and when it fails, the oven won't heat — even if the broil element and controls still work fine. Look for visible damage: a crack, a burn hole, or a section that has blistered or broken apart. A failed element often shows these signs clearly.

If the element looks intact but the oven still won't heat, a simple continuity test with a multimeter confirms whether it has failed internally.

Repair cost: $100–$200 parts and labor

Faulty Oven Temperature Sensor

The temperature sensor is a thin probe that extends into the oven cavity and signals the control board to cycle the element on and off. When the sensor fails or reads incorrectly, the oven may not heat at all, or it may heat erratically — reaching temperature sometimes but not others. The sensor usually sits in the upper back corner of the oven interior.

A bad sensor is often misdiagnosed as a control board problem. Testing the sensor's resistance with a multimeter is the right first step before assuming the board is at fault.

Repair cost: $100–$180 parts and labor

Defective Control Board

The control board manages every function of the oven — temperature regulation, timing, element cycling. When it fails, symptoms can look like almost anything: the display works but the oven won't heat, or it heats to the wrong temperature, or it simply doesn't respond. Control boards are the most expensive oven repair, and they're worth replacing only if the oven is otherwise in good shape.

Before blaming the board, make sure the temperature sensor and elements have been ruled out — a bad board diagnosis is common, but it's also the most expensive assumption to act on incorrectly.

Gas Oven Not Heating: The Two Main Culprits

Weak or Failed Igniter

The igniter is the most common reason a gas oven won't heat. It does two jobs: it glows hot enough to ignite the gas, and it draws enough electrical current to open the gas valve. When the igniter weakens, it may glow but not get hot enough to open the valve — so you see light but get no heat and no flame. A slow preheat is often the first warning sign before complete failure.

You can usually observe the igniter glowing through the bottom vent of the oven. A healthy igniter reaches full brightness quickly (under 90 seconds). One that glows dimly and takes several minutes to ignite — or never does — is on its way out.

Repair cost: $120–$220 parts and labor

Gas Safety Valve Failure

The gas valve controls the flow of gas to the burner. It works in tandem with the igniter: when the igniter draws sufficient current, the valve opens. If the valve itself has failed — separate from the igniter — gas won't flow even with a fully functional igniter. This is less common than igniter failure but follows the same symptom: igniter glows, no flame.

Differentiating between an igniter and a valve issue requires measuring the igniter's amperage draw. A technician can do this quickly with the right equipment.

Repair cost: $150–$280 parts and labor

What You Can Check Yourself Before Calling

Before scheduling a repair visit, run through these quick checks — some will save you a service call entirely:

Good to know: If your stovetop burners work but the oven won't heat, the problem is almost always isolated to the oven's bake circuit — either the element, igniter, or temperature sensor. The stovetop and oven use entirely separate heating systems on most ranges.

Repair Costs for Oven Problems in Tustin

Here's what oven repair typically costs in the Tustin and Orange County area:

Problem Typical Repair Cost Oven Type
Bake element replacement $100–$200 Electric
Temperature sensor replacement $100–$180 Electric / Gas
Igniter replacement $120–$220 Gas
Gas safety valve replacement $150–$280 Gas
Control board replacement $200–$400+ Electric / Gas
Diagnostic fee (usually waived with repair) $75–$100 All
Repair vs. replace threshold: If the repair cost exceeds 50% of what a comparable new range costs, replacement often makes more financial sense — especially on an oven that's more than 12 years old. For most element and sensor repairs, the math almost always favors repair.

When to Call a Technician in Tustin

Once you've ruled out the breaker, control lock, and any visible element damage, it's time for a professional diagnosis. The remaining causes — sensor resistance testing, igniter amperage measurement, valve testing — require equipment that most homeowners don't have. A Tustin-area appliance technician can typically diagnose a non-heating oven in under an hour and complete most repairs in the same visit if the part is on the truck.

Gas oven repairs should always be handled by a licensed technician. Even a gas valve swap involves working with the fuel line, and it's not worth the safety risk to DIY.

Frequently Asked Questions

Why did my oven stop heating but the stovetop still works?

The stovetop burners and the oven use separate heating elements or igniters. If your stovetop works but the oven doesn't heat, the problem is almost certainly isolated to the bake element (electric) or oven igniter (gas). This is good news — it narrows the diagnosis significantly and usually means a straightforward, affordable repair.

How do I know if my oven's bake element is bad?

A failed bake element often shows visible damage — blistering, a crack, or a burn mark. If the element looks intact but the oven still won't heat, test it with a multimeter for continuity. No continuity means the element has failed internally. Replacement is one of the more affordable oven repairs, typically $100–$200 including parts and labor.

How much does oven repair cost in Tustin, CA?

Oven repair in Tustin and Orange County typically runs $100–$350 depending on the part. A bake element replacement is $100–$200, a gas igniter is $120–$220, a temperature sensor is $100–$180, and a control board is $200–$400+. Most technicians charge a diagnostic fee of $75–$100, often waived if you proceed with the repair.

Is it worth repairing an oven that's 8–10 years old?

For most repairs under $250, yes — ovens typically last 13–15 years with normal use, so an 8–10 year old unit still has plenty of life. The exception is a control board failure: if the board costs $300+ and the oven is already showing other wear, replacing it may make more sense. A technician can give you an honest assessment after diagnosing the specific problem.

Can I still use the broil setting if my bake element is broken?

Yes. The bake element at the bottom and the broil element at the top are separate components. If only the bake element has failed, the broil function will still work. You can use broil as a temporary workaround for some cooking — but temperatures won't be as even as normal baking, and it's not suitable for dishes that need bottom heat.
