Furnace Won't Ignite
Furnace clicks but won't fire — usually a $200 fix, not a $9,000 furnace.
Call (209) 216-7240Symptoms you're seeing
- Thermostat calls for heat, blower runs, but no warm air
- Clicking or buzzing followed by lockout
- Furnace tries 3 times, then shuts down for an hour
- Yellow flame visible briefly then drops out
What's actually causing it
Most likelyDirty flame sensor — #1 cause, $200 fix
CommonCracked or worn hot surface ignitor
CommonClosed gas valve or low gas pressure
PossiblePressure switch fault from blocked vent
PossibleFailed control board
What to do right now
- 1Confirm the gas valve to the furnace is OPEN
- 2Check the thermostat is set to HEAT and the temp is above room temp
- 3Replace the air filter if dirty
- 4Look for blinking error codes on the furnace control board (count flashes)
- 5Don't keep resetting — repeated ignition attempts can flood the burners

FAQs
Is it safe to keep trying to start the furnace?
No — repeated tries can build up unburnt gas. Three failed cycles is the limit. Call us instead.
Can I clean the flame sensor myself?
Yes if you're comfortable — fine emery cloth, gentle wipe. But many sensors are within ohm-spec and the issue is something else, so a tech call usually pays off.
