You set the oven to preheat and… nothing. No heat, maybe no lights, maybe the buttons don't respond — yet the stovetop burners fire up just fine. It's one of the most confusing oven problems, because the appliance clearly has power. The good news: on most ovens, the bake side and the cooktop are separate systems, so a dead oven usually points to one specific, fixable part — not a whole new range.
Across 985 real oven repairs in the SF Bay Area & Peninsula, 214 were "won't start / won't turn on" jobs — our second most common oven call. We've diagnosed this exact split more times than we can count.
What customers tell us:
"GE — does not turn on, but the stove works. Buttons are not working." — a GE range owner
"Oven stopped working and panel freezes when the oven is on." — a Frigidaire owner
"Wolf oven just stopped working and did not get any error message." — a Wolf owner
Why the burners work but the oven is dead
On a gas range, the surface burners often light with a simple spark ignition that's independent of the oven's control system. The oven, by contrast, runs through the electronic control board, its own igniter or bake element, a temperature sensor, and safety circuits. So when the cooktop works but the oven won't turn on, the fault is almost always downstream in that oven-only chain — which actually narrows the search.
What we actually find — the top causes
1. Electronic control board / clock module. The board is the brain that tells the oven to power the bake circuit. When it fails or locks up, you get exactly what our customers describe: dead oven, frozen or unresponsive buttons, no error at all. The Frigidaire owner whose "panel freezes when oven is on" and the GE owner whose "buttons are not working" both point straight here. This is the single most common cause of a no-start oven in our data.
2. A failed igniter (gas ovens). On a gas oven, if the igniter is completely dead, the safety valve never opens and the oven never heats — it can look like it "won't turn on" even though the controls light up. Igniters are among the parts we replace most on ovens, and these part numbers show up among our most-used oven parts: 5303935066 (Frigidaire) and GE's WB26X35089 / WB26X31060.
3. A burned-out bake element (electric ovens). If the element has an open circuit, the oven powers up but produces no heat. Several customers describe this as the oven "not turning on" when really it's turning on but not heating — like the GE owner whose "oven light comes on, but it doesn't heat up."
4. Thermal fuse, door lock, or safety switch tripped. A tripped thermal cut-off (often after a self-clean cycle) or a stuck door-lock can cut power to the bake circuit and leave the oven dead. Bosch owners sometimes see an Error 45 locking-mechanism fault in this family. These are usually inexpensive parts.
5. Power / wiring to the oven circuit. Occasionally a tripped breaker leg, a loose connection, or a wiring fault feeds the cooktop but not the oven. One of our customers had even switched "the oven switch in the breaker box on and off" trying to reset it — worth doing, but if it doesn't come back, it's a tech visit.
Try this before you book (2 minutes)
- Reset the power. Flip the oven's breaker fully OFF, wait 60 seconds, and back ON. A frozen control board sometimes clears with a hard reset — the same idea as rebooting a computer.
- Check for a stuck control lock or Sabbath/delay mode. Many ovens have a child-lock or a delayed-start setting that makes the oven look dead. Hold the lock button a few seconds; check the manual for the delay-bake symbol.
- Confirm the door isn't stuck in the locked position from a self-clean cycle. If it's locked, the oven won't run.
If the oven is still dead after all that, the fault is a component — and that's where we come in.
Honest DIY vs. call a pro
The steps above are safe for anyone. Beyond that, diagnosing a no-start oven means metering the control board, igniter, element, thermal fuse, and door switch to find which link in the chain is broken — and those parts are behind the back panel, next to live 240V wiring on electric ovens or the gas valve on gas ovens. Swapping the wrong part (a common mistake is replacing a control board when it's actually a failed igniter, or vice versa) gets expensive fast. A tech confirms the real fault first, then replaces one part — not three on a guess.
What it costs
We won't name a part price sight-unseen, because "won't turn on" can be a cheap thermal fuse or a pricier control board. What's honest: across 985 Bay Area oven repairs, the median came to about $330. An igniter or element replacement tends to land in a common, moderate range; a full control-board swap runs higher.
Our visit includes a diagnostic fee, and that fee is credited toward the repair when you approve it — so you only pay to diagnose once. You'll always see an upfront, all-in price before any work begins.

Frequently asked questions
Why won't my oven turn on but the stove/burners still work? Because the cooktop and the oven are usually separate systems. The surface burners often light independently, while the oven runs through its own control board, igniter or element, and safety circuits. So a dead oven with a working stove almost always means one oven-only part has failed — most often the control board or, on gas ovens, the igniter.
My oven buttons aren't working — is it the control board? Often, yes. Unresponsive or frozen buttons and a no-start oven are the classic signature of a failed or locked-up electronic control board — exactly what our customers describe when the "panel freezes" or "buttons are not working." First try a hard reset at the breaker; if the buttons are still dead, it's a board diagnosis.
My oven won't turn on and there's no error message — what now? No error code doesn't mean no fault. Plenty of our no-start ovens threw no message at all, like the Wolf that "just stopped working." Do a breaker reset and check for a control lock or delay-start mode. If it's still dead, a tech meters the board, igniter, element, and thermal fuse to find the broken link.
The panel freezes when I turn the oven on — is it fixable? Yes. A freezing or unresponsive panel is typically a control-board issue, and it's a standard replacement for us. Try a full power reset first (breaker off 60 seconds, back on); if the panel still locks, book a diagnostic and we'll confirm whether it's the board or something feeding it.
How much does it cost to fix an oven that won't turn on? It depends on the part. A thermal fuse or igniter is a moderate fix; a control board runs higher. Our median oven repair across 985 Bay Area jobs was about $330. You'll get an upfront price before work starts, and the diagnostic fee is credited toward the repair when you approve it.
Can I fix an oven that won't power on myself? The safe DIY steps are a breaker reset, checking for a control lock or delay-start mode, and making sure the door isn't stuck locked from self-clean. Beyond that, diagnosing a no-start oven means testing components next to live 240V wiring or a gas valve behind the back panel — best left to a licensed tech so you replace the one part that's actually failed, not three on a guess.
