Wiring problems

The wiring between the thermostat and the HVAC equipment may be faulty or damaged, causing a miscommunication between the two. This can result in the fan running even when the equipment is supposed to be off.

Faulty sensors

The sensors in the HVAC equipment may be malfunctioning, causing the system to think that the equipment is off when it is actually running. This can result in the fan running to circulate air even when the heating or cooling function is not activated.

Malfunctioning relays

The relays in the HVAC equipment may be malfunctioning, causing the system to run the fan even when it is supposed to be off. Relays are responsible for turning on and off the various components of the system, so a malfunctioning relay can cause unexpected behavior.
