Why Won’t Your Furnace Shut Off in Punta Gorda, FL?

As winter approaches in Punta Gorda, FL, cooler temperatures can have many people turning on their furnaces for warmth. Sometimes, furnaces won’t automatically turn themselves off. Here are a few reasons your furnace won’t power down:

Fan Switched From Auto to On

It’s easy to confuse the sound of a fan with the sound a furnace makes. Check your thermostat and look at its fan setting. If it’s not already correct, set your thermostat’s fan setting from on to auto.

Lower the temperature setting to 50 degrees. Next, wait a few minutes to let the fan fully power down. If your fan is on the auto setting and still blows out air, you’re likely dealing with a furnace problem.

Faulty Wiring

Another common cause of furnace problems involves a thermostat’s wiring. Many wires connect and run through modern thermostats. Even one faulty wire can lead to a furnace that never shuts off.

Working with electrical wires is a complex and potentially dangerous task, so it’s best to leave this work to a professional. One of our experts can safely determine if faulty wiring is to blame for a constantly running furnace.

Broken or Damaged Blower Motor

Modern HVAC systems require a lot of components working together to operate properly. One of these important parts is a blower, which helps push warm or cool air throughout your home. It’s possible for faulty blower motors to either stop airflow or function non-stop.

This might require a simple repair, or you may have to purchase a new blower. Since there are many possible blower-related problems, it’s best to have one of our HVAC professionals fix these kinds of issues.

Continuously running furnaces can happen for many reasons. Contact All American Heating & Cooling to have a professional find and repair your furnace problem. We’ll do so safely in the most cost-effective way.
