furnace won't turn off

While it’s great to have a furnace during the winter, it’s not so great to have one that constantly runs without turning off. In addition to raising your heating bill, a furnace that doesn’t shut off also makes temperature control impossible. If you don’t address it soon enough, it could damage your furnace or even cause a house fire.

If your furnace won’t turn off, have a respected HVAC company in Cape Coral, FL, explain how you can diagnose and fix the problem. Our Coral Air Conditioning team will explain why your furnace is continuously running and how you can take control of the situation to turn it off safely.

Why Your Heating System Won’t Stop and How You Can Fix It

If you’re experiencing endless furnace cycling, you can resolve your constant heating issues by contacting an HVAC professional right away. If your furnace won’t shut down, it may be because of the following:

Thermostat Malfunction

Your thermostat tells your heater what to do. If it’s broken, it can impact your heater, causing continuous furnace operation.

First, try turning the thermostat down to your desired temperature. If the inability to turn off the furnace persists, reset your thermostat by holding down the power button on the device. After waiting for 30 seconds, turn the thermostat back on and set it to your desired temperature.

If you’re furnace is running at a set temperature despite what your thermostat says, this means that the problem is with your furnace rather than your thermostat. In order to turn your furnace off, cut the power.

To cut off the power for your furnace, locate the power switch for your unit, which is usually on or near the machine. Once your system has shut down successfully, don’t power it on again until you’ve called a professional to help handle the issue.

Faulty Furnace Limit Switch

If your furnace won’t turn off, check the limit switch.

The limit switch is your furnace’s sensor for the blower motor. When triggered, the switch will turn the blower motor on to dissipate heat from the furnace to the home. If you have a faulty limit switch, your blower motor may run continuously even though no heat is coming through your vents.

Just like any other sensor, your limit switch can expire with time. If you suspect your limit switch is to blame for a continuously running motor, call a professional HVAC technician in Cape Coral, Florida so that you can get a replacement in order.

Leaking Air Ducts

Depending on your furnace’s location and model, some types may be more susceptible to duct leaks than others. If your air ducts are old, they may leak hot air as your furnace attempts to heat your home, pumping hot air into the furnace room. Typically, this only happens with furnaces that operate from attics since heat rises and can manipulate your furnace’s functions.

What To Do When Your Furnace Won’t Turn Off in Your Cape Coral, FL, House

  2. In order to turn off your furnace, locate the breaker for your unit.
  3. After turning your breaker for the furnace off, locate the power switch for your heating system. It may be on or near your furnace. If you’re having trouble locating it, consult your maintenance manual for instructions on how to turn your furnace off.
