Why Won’t My Furnace Stop Running?

An unresponsive furnace can be extremely irritating, particularly if it refuses to turn off. Not only can this be uncomfortable for residents of any household with heating systems installed, but increased energy consumption may also occur, and potential system damage. When confronting such a dilemma, there are various factors you should take into consideration to diagnose and address the source of unstoppable furnaces. Zion Custom Air can assist with furnace repair and even AC repair, but here are some things you can check first.

Do You Have Appropriate Thermostat Settings?

One of the key aspects to keep an eye out for when your furnace won't stop running is your thermostat settings. Check that they match up to the desired temperature and mode (heat or auto), otherwise set "ON" or "Continuous Fan," the furnace blower may remain active even after reaching desired temperature has been achieved; switch it instead to "AUTO" or "Heat" mode to allow your furnace to cycle on and off as needed.

• Filters Should Be Replaced Regularly: A dirty air filter can force your furnace to run too long. By restricting airflow, blocked filters make it harder for the unit to heat your home efficiently - as such, it may continue running as it attempts to reach desired temperature levels. Therefore, regular inspection and replacement according to manufacturer recommendations are vital to maintaining efficient airflow & thus helping limit runtime.
• Check Your Pilot Light: A gas furnace's pilot light can become inoperable if its performance becomes compromised, so regular checks are recommended to ensure it is lit and burning steadily. If the pilot light goes out or flickers unexpectedly, follow the manufacturer's instructions on relighting safely. Should it persist in extinguishing or any irregularities be identified - professional evaluation and repair service providers should be contacted as soon as possible for evaluation and repairs.

Potential Concerns that May Require Professional Assistance

While some furnace issues can be addressed through basic troubleshooting, others may require the expertise of an HVAC technician. Below are a few potential concerns that could be leading to your furnace running continuously:

• Leaking Ductwork: Duct leakage can result in the loss of heated air, necessitating additional furnace runs to compensate. Inspect your ducts regularly for gaps, holes, or loose connections and any signs of potential leakage; should any be detected, seek assistance from an HVAC technician as soon as possible who will seal or repair them to minimize heat loss and extend the furnace lifespan.
• Breakdown Fan Motor: An improperly functioning fan motor may prevent the furnace from cycling on and off properly. If your blower fan doesn't stop spinning, this could indicate an issue with its fan motor; professional attention may be necessary for diagnosing and replacing it as soon as possible.
• Faulty Thermostat: An inaccurate thermostat can lead to irregular furnace behavior and continuous operation. Check whether your thermostat displays the appropriate temperature, responds accurately when adjusted, and displays correct temperatures when set or reset. If a malfunction is suspected, consider having it examined and possibly replaced by an HVAC professional.
