Seven months of work, and wind and ice besides
Your furnace runs from October through April here, seven months of the year. On winter nights that average 25°F, it cycles on and off many times a day to keep up. Each cycle is a start, and the igniter and the flame sensor take the wear from that. When one of them finally gives out, the burner won't light and the house goes cold.
Greene County has logged 14 winter storms and 302 damaging wind events over the past ten years. Wind like that can push a furnace's vent hood out of position or knock the venting loose, and either one will shut the furnace down. Storms also knock out power, and close to a fifth of Missouri households went at least 24 hours without it in 2024. Most furnaces need electricity to run the blower and controls, so when the power drops, so does your heat, even with gas still supplying the burner.

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 of the time it's the thermostat, a tripped breaker, or the switch that looks like a light switch near the furnace itself, sometimes it gets bumped off. Check that the furnace switch is on and the breaker hasn't tripped before anything else. If those are fine, it could be the igniter or a safety switch that shut the furnace down on purpose. With lows around 25°F through the winter here, it's worth getting this looked at quickly rather than waiting.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running the blower without the burners lighting. That points to an ignition problem or a safety switch stopping the burners while the fan keeps going. It can also mean the thermostat fan setting is on instead of auto, which runs the blower even when no heat is being made. Check that setting first since it's the easiest thing to rule out.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple isn't sensing the flame and is shutting off the gas as a safety measure. A draft blowing out the pilot is another common cause, especially if the flame looks weak or yellow instead of steady blue. Either way this isn't something to keep relighting on your own, since it points to a part that needs replacing or a venting issue that needs a look.
