Category: FurnaceFurnace turns on for 5-10 seconds, then off, the back on and runs perfectly fine.

Is this an issue? Does my furnace just need a sensor cleaning? I’d hate to have to replace the whole unit.
Does your company do furnace maintenance as well? Thanks!

Hi Kelly,

The first (and most common) cause of short cycling furnace is a dirty air filter. A dirty filter restricts air from reaching your furnace’s heat exchanger, which causes your furnace to overheat and then shut down. Eventually, it will turn back on and the process will repeat itself.
