Seven months of work, twenty-four degree nights
Raymore needs heat from October through April. That is seven months of the burner cycling on and off, on nights that average 24°F. Each cycle is another start, and the igniter and the flame sensor are what take that wear. When one of them finally gives out, the furnace either won't light or shuts itself off partway through the cycle.
Cass County has logged 9 winter storms and 89 damaging wind events over the past ten years. Most gas furnaces need electricity to run the blower and controls, so when a storm knocks out power on a cold night, the furnace stops with it, even though the gas line is fine. Statewide, 19% of Missouri households went at least 24 hours without power in 2024.

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 and the power to the unit. Check that the thermostat is set to heat and a few degrees above room temperature, then check the furnace switch, the breaker, and that the filter isn't so clogged it's shutting things down. If those are all fine, the igniter or a safety switch may be failing, and a contractor will need to test it. With winter lows here averaging 24°F, it's worth getting this looked at quickly rather than waiting.
- Why is my furnace blowing cold air?
- Most often the furnace is just starting a cycle and hasn't warmed up yet, so give it a few minutes before assuming something's wrong. If the air stays cold, check that the thermostat fan setting is on auto, not on, since a fan running constantly will pull in room air between heating cycles and feel cold. A dirty filter can also block enough airflow to keep the burners from firing properly. If none of that explains it, the igniter or gas valve may not be working and a contractor should check it.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple is worn out and no longer sensing the flame correctly, so the gas valve shuts off as a safety measure. A draft blowing across the pilot or a dirty pilot orifice can cause the same thing. Relighting it yourself may work for a night, but if it keeps going out, the part needs to be replaced. This isn't something to leave alone for long with 7 months of heating season ahead.
