Ten months of heat wears on a Sundance furnace
Your furnace runs from September through June here, ten months of the year. On winter nights averaging 12°F, it has to cycle on and off for hours at a stretch to keep the house warm. Each start puts strain on the igniter and the flame sensor, the parts that get the burner lit and keep it lit.
Crook County has also logged 76 winter storms and 123 damaging wind events over the past ten years, and power can go out with them. When it comes back on, your furnace has to start and light correctly right when the cold is at its worst. A furnace already worn from a long heating season is the one most likely to fail on that kind of night.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat the way it should, or power isn't reaching the furnace. Check that the thermostat is set below room temperature and has working batteries, and check the breaker and the furnace's own power switch, which looks like a light switch near the unit. If those are fine, the igniter or the flame sensor may have failed, and a furnace won't run without either one working. With winter lows here averaging 12°F, a furnace that won't start needs attention fast, so a contractor should look at it the same day if you can't find the problem yourself.
- 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, a clogged filter starving it of airflow, or a limit switch shutting the burners off to protect the unit from overheating. It can also just be the blower running a normal delay before the heat exchanger warms up, so give it a few minutes before you assume something's wrong. If cold air keeps blowing after that, a contractor will need to find out why the burners aren't firing.
- 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. It can also happen if there's a draft near the pilot or the pilot orifice is dirty. Since a standing pilot burns without needing electricity, this isn't a power problem, and a contractor can typically replace the thermocouple without much trouble.
