What Causes Furnace Short Cycling?

There are a few possible causes of furnace short cycling. One common issue is a dirty air filter. When the air filter is clogged, it can restrict airflow to the furnace, causing it to overheat and turn off prematurely. Another possible cause is a faulty thermostat. If the thermostat is malfunctioning, it may send incorrect signals to the furnace, causing it to turn on and off too often. Finally, furnace short cycling can also be caused by a problem with the furnace itself, such as a faulty blower motor or a clogged heat exchanger.

How to Fix Furnace Short Cycling

If you’re experiencing furnace short cycling, there are a few things you can do to try and fix the problem. First, check the air filter and replace it if it’s dirty. If the air filter is clean, then the next step is to check the thermostat. Make sure that the thermostat is set to the correct temperature and that it’s not malfunctioning. If the thermostat is working properly, then the next step is to call a qualified HVAC technician to inspect the furnace and repair any problems.

Tips to Prevent Furnace Short Cycling

In addition to fixing the underlying cause of furnace short cycling, there are a few things you can do to help prevent the problem from recurring. First, make sure to change the air filter regularly. A clean air filter will help to ensure that the furnace is getting enough airflow and that it’s not overheating. Second, keep the area around the furnace clear of obstructions. Obstructions can restrict airflow and cause the furnace to overheat. Finally, have the furnace inspected and serviced by a qualified HVAC technician every year. Regular maintenance can help to catch potential problems early and prevent them from causing furnace short cycling.
