Nine months of heat puts real wear on a Cheyenne furnace
Your furnace runs from September through May here, nine months of the year. On winter nights that average 16°F, it is not lighting once and holding steady. It cycles on and off for hours, and every start puts load on the igniter and the flame sensor.
Cheyenne has logged 382 winter storms and 1,869 damaging wind events over the past ten years. Wind like that can push cold air back into the flue and affect how the furnace drafts. Most furnaces come back on their own once power returns after a storm, but if yours does not light again, that is worth a call.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
- Why won't my furnace turn on?
- Start with the thermostat. Make sure it's set to heat and the temperature you want is above the room temperature, since a stray setting is an easy thing to miss on a cold morning. Check the breaker next, because a tripped one will shut the whole system down. If power and settings look fine, the igniter or the flame sensor may have failed, and that's a job for a contractor to test and replace.
- Why is my furnace blowing cold air?
- Most often this means the blower is running but the burners haven't lit. Check your filter first. A filter clogged enough restricts airflow across the heat exchanger, and the furnace can shut the burners off to protect itself while the fan keeps blowing. If the filter looks fine, the igniter or a gas valve issue could be keeping the burners from firing at all, and a contractor will need to check it.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small sensor that tells the gas valve the pilot is actually burning. When it wears out or sits out of position, it reads the flame as out even when it isn't, and the valve shuts the gas off. A draft blowing across the pilot can cause the same problem, so check for anything nearby stirring the air. Either way, a contractor can test the thermocouple and replace it if it's worn.
