Ten months of heat puts real wear on a Douglas furnace
Your furnace runs from September through June here, with only a short break in summer. On winter nights that average 14°F, the burner cycles on and off for hours at a stretch, and every start puts wear on the igniter and the flame sensor.
Converse County has logged 105 winter storms and 141 damaging wind events over the past ten years. Wind and ice both strain the power grid, and 8% of Wyoming households went at least 24 hours without power in 2024. A furnace that loses power mid-cycle during weather like that has to restart cold and relight, which is exactly when a weak igniter or a failing sensor gives out.

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?
- Most often the thermostat is asking for heat but the furnace isn't getting power or gas to answer. Check that the switch on the furnace itself, the one that looks like a light switch, is on, and that the breaker hasn't tripped. If the filter is packed with dust the furnace may be shutting itself off to protect against overheating. When none of that explains it, the igniter or a safety switch inside the unit has likely failed, and that's a job for a contractor to open up and test.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may just be starting its cycle, since a furnace pushes air before the heat exchanger is fully warmed up. If cold air keeps coming, the burners aren't lighting even though the blower is running. That points to a gas supply problem or an igniter that isn't doing its job, and a contractor will need to check both.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is usually a sign the thermocouple has worn out. That's the small part that senses the flame and tells the gas valve it's safe to keep the gas flowing. When it fails, the valve shuts the gas off as a safety measure even though the pilot lit for a second. A draft blowing out the flame or a dirty pilot opening can also cause it, so it's worth having a contractor look at the whole assembly rather than guessing.
