Short cycling occurs when your furnace turns on and off quickly, sometimes after even just a few seconds. Here are a few reasons why your furnace in your home in Brunswick, GA may short cycle.
Your Furnace Is Too Big for Your House
When you install a new furnace, the professional technician who does the work should perform all the necessary calculations to determine the size you need. A system that is too big will heat the house to the desired temperature before the cycle even finishes, turning off too quickly. After that, the house will cool, and the process will repeat itself.
The Thermostat Could Be Faulty
If the thermostat is sending incorrect signals to the furnace, then it could turn on and off too quickly. This could be caused by something as simple as needing new batteries, but it also could mean that you need a new thermostat. One of our technicians can let you know if you do.
Something Is Amiss With the Furnace
Furnaces have many moving parts and electrical systems. Any one of them could cause short cycling if it malfunctions. For example, the fan limiter keeps the heat exchanger from getting too hot. If it fails, then the system could shut off.
The culprit could also be a broken igniter. If the igniter doesn’t work, then the system won’t light. Instead, it will shut off to prevent a dangerous buildup of gas.
There could also be clogs in various locations, including the flue and the air filter. These clogs can interfere with smooth airflow, causing the furnace to shut off too quickly.
