Symptoms
- Burners and oven won't ignite when there's no power
- Display and clock are blank
- Manual lighting with a match may still work on very old models without electric ignition
- Everything returns to normal once power is restored
Likely causes
- CommonNo household power reaching the range's ignitersMost modern gas ranges use electric spark or hot-surface igniters that require power.
- PossibleBreaker not reset after power returnsSometimes a breaker trips during an outage's power surge and needs manual resetting.
- PossibleControl board needs a reset after a power surgeSome boards get confused by irregular power and need a restart.
- Less commonActual gas supply interruptionIf the outage was tied to a larger utility event, gas supply itself could also be affected, which is separate from the range.
What to do
- Confirm whether your home's power has actually been restored by checking other outlets or lights.
- Check the breaker for the range and reset it if tripped.
- If power is confirmed on but the range still won't ignite, unplug it for about a minute and plug it back in to reset the control board.
- Try lighting a burner again; a hot-surface or spark igniter should respond once power is confirmed present.
- If your range is old enough to have a standing pilot, it doesn't need power for burners, but the oven may still need electricity for its safety valve on some models.
- If the range still won't work with confirmed power, treat it as a normal ignition issue and check the relevant guide (igniter, valve, etc.).
When to call a pro
If power is confirmed but the range still won't ignite after a reset, an appliance technician can check the igniter and control board.
