Why Is My Furnace Short Cycling?
Short cycling refers to a furnace turning on and off frequently within a short period of time. This not only wastes energy and increases utility bills but can also lead to premature component failure. Here are some common reasons why your furnace may be short cycling:
- Oversized furnace: An oversized furnace will heat your home too quickly, causing the thermostat to shut it off before it can complete a full cycle.
- Dirty filter: A dirty air filter will restrict airflow, causing the furnace to overheat and shut off prematurely.
- Malfunctioning thermostat: A faulty thermostat may send incorrect signals to the furnace, causing it to short cycle.
- Blocked vents or ducts: Obstructions in vents or ducts can restrict airflow and cause short cycling.
- Flame sensor issues: A dirty or malfunctioning flame sensor can prevent the furnace from igniting properly, leading to short cycling.
