The most common cause of an oven that won’t heat depends on fuel type: on gas ovens it’s almost always a weak or failed igniter, and on electric ovens it’s usually a burned-out bake element. Work through the checks below in order for your oven type before assuming the control board is at fault.
This page is part of our full oven troubleshooting guide.
Quick Diagnosis Table
| Cause | Likelihood | Difficulty | Typical Part Cost |
|---|---|---|---|
| Weak or failed igniter (gas ovens) | Very likely on gas | Moderate | $15–40 |
| Burned-out bake element (electric ovens) | Very likely on electric | Easy to moderate | $20–60 |
| Sabbath/Demo mode switched on | Possible | Easy (no tools) | $0 |
| Tripped breaker or blown thermal fuse | Possible | Easy to check | $0–20 |
| Faulty oven temperature sensor | Possible | Moderate | $15–35 |
| Defective electronic control board | Rare | Professional recommended | $100–250+ |
Repair or Replace?
Every cause on this page except a control board costs under $60 in parts and under an hour of your time, so repairing is the clear choice. A control board replacement on an oven older than 10 to 12 years is usually the point where a new range makes more financial sense than another repair.
Whirlpool, GE, and Samsung place the igniter, element, and reset procedure a little differently. Brand-specific guides are available for Whirlpool, GE, and Samsung ovens.
Frequently Asked Questions
My gas oven's igniter glows but the burner never lights, what does that mean?
If the igniter glows for 90 seconds or more without igniting the gas, it's too weak to open the safety valve, even though it's still producing some heat and light. That's a worn igniter, and it needs replacing rather than further testing.
How do I know if my bake element has failed without seeing obvious damage?
Turn the oven on and watch the element. A healthy one glows uniformly red-orange within a couple of minutes. No glow at all, or a glow that stops partway along the coil, points to a failed or broken element even without visible cracks or blisters.
Can Sabbath mode or Demo mode really stop an oven from heating?
Yes, on several brands. Both are legitimate settings, not malfunctions, but they look identical to a heating failure from the outside. Check your control panel for either mode before opening up the oven.
Is it safe to test a gas igniter myself?
Testing it visually, watching whether it glows and ignites the gas within 90 seconds, is safe with the oven running normally. Removing and testing it with a multimeter requires shutting off the gas and power first; if you're not comfortable doing that safely, leave it to a technician.
My oven tripped the breaker, is that the element or something else?
A tripped breaker points to a short somewhere in the circuit, often the bake element itself failing internally rather than just burning out visibly. Don't keep resetting the breaker repeatedly; if it trips again right away, stop and call a technician.
How much does a control board replacement typically cost?
Parts alone usually run $100 to $250 depending on the model, plus professional labor. On an older oven, that's often close to the cost difference toward a new range.
