Furnace Repair
When a furnace won't ignite in Parker, CO, you may hear the inducer motor and a click, but no flame follows. On older units the pilot light may not stay lit. Ignition parts wear out, and they tend to fail on the first cold nights of the season.
Call (303) 647-3227
Most modern furnaces use a hot surface ignitor that glows to light the gas. Ignitors crack with age. Furnace ignitor replacement is one of the most common winter repairs.
Older furnaces use a standing pilot. If the furnace pilot light won't stay lit, the thermocouple may be worn, or the pilot may be dirty or getting a weak flame.
If the ignitor glows but no gas flows, the gas valve or the supply may be the problem. This is a job for a contractor only.
Repeated clicking can mean the furnace is trying to light and failing, then retrying. After several tries most furnaces lock out.
✓
Confirm the thermostat is on Heat and set above room temperature.
✓
Check that the furnace power switch is on and the breaker has not tripped.
✓
Replace a dirty filter.
✓
Turn the power switch off for a minute, then on again, to clear a lockout once.
Safety first
If you smell gas, do not touch switches or try to relight anything. Leave the house, then call Xcel Energy or 911 from outside.
Call if the furnace still clicks without lighting, if the pilot will not stay lit, or if it locks out again. A contractor can test the ignitor, flame sensor and gas valve and tell you which part has failed.
The blower can run without the burners. If the ignitor is cracked or the flame sensor is dirty, the furnace will not hold a flame, and the fan may still move air.
A worn thermocouple is the most common cause. A dirty pilot or a draft near the furnace can also put it out. A contractor should handle the repair.
If you can see through the burner window and the ignitor never glows, or it glows and then the furnace fails, the ignitor is a likely suspect. A contractor can test it.
