Along with the rest of your heating and cooling system, your HVAC fan should also turn on and off. While it is typical for the fan to turn on for a few minutes prior to heating or cooling beginning, it shouldn’t operate continuously for long periods of time. While it may not always be bad for your fan, this is typically an indication of something more serious. A malfunctioning thermostat, poor wiring, and jammed relays are some reasons why residents in Wood River, IL are having issues with their fan turning off.
Thermostat Settings: Verify that the thermostat is set to “on” instead of “auto.”
Extreme Temperatures: Your HVAC system might not have enough power to achieve your desired temperature if the outside temperature is extremely hot or cold. This could happen if your system is too small or hasn’t been properly maintained. This will cause it to keep running until the outside weather changes.
Faulty Thermostat: You can have a malfunctioning thermostat if both the fan and either the cooling or heating system run unexpectedly.
Broken Relay Switch or Short Circuit: If only the fan is operating, there can be a malfunctioning relay switch that prevents the fan from receiving the settings you set on the thermostat. Similar to this, a short circuit or other wiring issue could be obstructing the transmission of the on/off orders to your fan.
