Seven months of Sedalia winter wears on a furnace
Your furnace runs October through April here, and on the nights that average 24°F, it cycles on and off for hours to keep the house warm. Each start puts a load on the igniter, and over seven months that wear catches up with it. A furnace that won't light, or lights and then shuts off again, is often telling you the igniter is going.
Pettis County has seen eight winter storms and 47 damaging wind events over the last ten years, and either one can knock out power. In 2024, 19% of Missouri households went at least a day without it. 44.7% of homes here heat with electricity, so when the power goes, so does the furnace. Most come back on by themselves once power returns. If yours doesn't, that's worth a call.

- Why won't my furnace turn on?
- The most common reason is the thermostat isn't calling for heat, or power to the furnace has been interrupted. Check that the thermostat is set below room temperature and has fresh batteries if it uses them. Next check the furnace switch, the one that looks like a light switch near the unit, and the circuit breaker. If those are fine, a safety switch inside the furnace may have shut it down, and that calls for a contractor to find out why.
- Why is my furnace blowing cold air?
- Usually this means the blower is running but the burners haven't lit. Furnaces blow air for a short time before the flame kicks in, so a few seconds of cool air is normal. If it keeps blowing cold the whole cycle, the igniter or flame sensor likely failed and the furnace isn't producing heat at all. A dirty filter can also cause this by making the furnace overheat and shut the burners off early, so check that first.
- Why won't my furnace pilot light stay lit?
- This almost always points to the thermocouple, the small sensor that tells the gas valve a flame is present. When it wears out or sits out of position, it reads no flame even when one is lit, and the valve shuts the gas off. A draft blowing out the pilot is the other common cause. Either way this isn't something to keep relighting on your own, since it means gas is flowing without a working safety check behind it. A contractor can test the thermocouple and replace it if needed.
