Cold weather is here and homeowners need to be ready to combat cold temperatures with a properly functioning furnace. There can be many reasons for cold weather furnace repairs this winter – a furnace turning off and on repeatedly, called short cycling, is one such concern. With knowledge under your belt, you can understand the reasons for short cycling to prevent cold weather furnace repairs.
What is Short Cycling
A furnace turns on and cycles to heat the home to a desired temperature. Once the temperature is met, the furnace turns off. This is normal but what isn’t normal is for the furnace to be turning on and off in repeated short bursts. This quick cycling of the furnace turning on and off is known as short cycling. A furnace turning on and off constantly can affect the unit’s efficiency and can be a sign of a serious problem.
Air Flow Restrictions
A typical cause of a furnace turning off and on is restricted airflow. Often times if a filter is too restrictive, it can cause your furnace to short cycle repeatedly. This is caused by using a filter that is not appropriately rated for your furnace, or a dirty one. You can try changing your current filter to the recommended filter for your specific brand and model of furnace system, and changing your filter regularly.
Another reason for restricted airflow is blocked vents. Double check your vent registers to allow your furnace to heat your rooms without any restrictions.
If your thermostat isn’t mounted in a productive and efficient location, it can cause your furnace to short cycle. A thermostat should be placed on an interior wall in a room that is frequently used. If this is the cause, you should contact Estes Services and have one of our technicians come to move the thermostat to a better location in your home.
If your filter is clean, offering good airflow, and your thermostat is located in a prime location, your furnace turning off and on could be caused by something more serious. These causes of a furnace turning off and on repeatedly require a professional to perform a cold weather furnace repair:
- Circuit board issues
- Inducer is malfunctioning
- Cracked heat exchanger
- Dirty flame rod
- Water present in tubing
- Pressure switch has failed
