Why won’t my furnace turn off or stop blowing heat?

If you have a furnace that has a faulty high limit switch, or needs to be reset, you can end up with heat blowing at you at all times of the day or night, regardless of temperature. If the limit switch has malfunctioned, the problem needs to be fixed as soon as possible, before your furnace can overheat and catch fire. While you’re having the limit switch replaced, we’ll also make sure you don’t have a clogged air filter, which can cause a build-up of heat in the furnace.

Why isn’t my furnace working?

A faulty fan limit switch can also play a key role in the underperformance of your heater. Problems with this switch can cause the fan to stop working instead of allowing the warmed air through the vents. You can quickly check the health of your fan motor by turning the thermostat from “auto” to “on.” You should hear the fan begin whirring, and you should also feel air coming from the vents.
