Oven Convection Fan Not Working? 6 Causes and What to Do
A convection fan that will not spin is usually a failed fan motor, a seized blade, a door switch or a relay on the control board. Here is how to narrow it down.
Read the guideWhy won't my oven turn on?
An oven will not turn on when power, gas or a control signal is not getting through. For a fully dead oven, check the breaker, the outlet and whether the clock needs to be set after a power outage. If the display works but there is no heat, the usual cause is a weak igniter on a gas oven or a burnt bake element on an electric oven. A tripped thermal fuse, a control lock, or a failed control board can also stop the oven.

Is the oven dead, or does it light up but not heat?
Look at the display first. A blank display means no power is reaching the control. A working display with no heat means power is fine, but something in the heat path has failed. This split saves time.
| What you see | Most likely causes |
|---|---|
| Blank display, no lights | Tripped breaker, loose plug, blown fuse, failed board |
| Display works, no heat (electric) | Burnt bake element, thermal fuse, relay on board |
| Display works, no heat (gas) | Weak igniter, gas valve, gas supply off |
| Display flashes or shows a code | Sensor fault, control lock, clock not set |
What are the 7 most common causes?
1. Tripped breaker or loose plug
Electric ovens use a double breaker. One half can trip and leave the display on while the oven will not heat. Gas ovens plug into a normal outlet that can lose power too.
2. Clock not set after a power outage
Many ovens will not run until you set the clock again. Bay Area outages during winter storms often cause this.
3. Control lock turned on
A child lock or Sabbath mode can block the bake button. Press and hold the lock key for a few seconds, or check your manual.
4. Weak gas igniter
The igniter must get hot enough to open the gas valve. A worn one glows orange but never gets there, so no flame appears. This is the top cause of a gas oven that will not light.
5. Burnt bake element
On an electric oven, look at the bottom element. A blister, a break or a dark spot means it has burned out. The broil element may still work.
6. Thermal fuse
Many ovens have a safety fuse that blows if the oven overheats. A failed self-clean cycle often blows it. Our guide to oven self-clean problems explains why.
7. Control board or temperature sensor
A bad relay on the board or a failed sensor can stop the oven from heating. This needs testing with a meter.
What can you check yourself?
- Check the breaker panel and reset any tripped oven breaker once.
- Set the clock and try the bake function again.
- Turn off any control lock or Sabbath mode.
- On a gas range, light a stovetop burner to confirm gas is on.
- Look at the bake element for breaks or blisters with the oven cold.
Do not work on gas lines yourself. If you smell gas, leave the home and call PG&E gas safety or 911 from outside. Get more advice on cooking safety from the NFPA cooking safety page.

When should you call a technician?
Call if the breaker and clock are fine but the oven still will not heat, if a gas oven igniter glows but no flame appears, if you see a broken element, or if the oven shows an error code. These need parts testing. Most oven repairs in Mountain View run about $150 to $500 with parts and labor, and you get the price first.
If the oven lights and runs but never gets hot enough, see our guide on an oven that is not heating. If your oven does heat but cooks unevenly, read our guide on an oven not preheating all the way. If a stovetop burner will not light, read gas stove burner won't light. Deciding whether to fix an old range? See the repair or replace guide.
Frequently asked questions
Why does my oven display work but the oven won't heat?
Power reaches the control, but not the heat parts. On an electric oven, check the bake element and fuse. On a gas oven, the igniter is the most common cause.
Why won't my gas oven light but the stovetop works?
The burners and oven use separate igniters and valves. A weak oven igniter often glows but never opens the gas valve.
How much does oven repair cost in Mountain View?
Most oven repairs run about $150 to $500 with parts and labor. Igniters and elements are usually at the lower end. You get the price first.
