What to do if Trane Control Unit fan is on but not running?
- DDiana HendersonSep 7, 2025
If the fan is set to ON but not running in your Trane Control Unit, it could be because: * The Smart Continuous Fan feature has been engaged. If indoor humidity is higher than the desired setpoint, the blower will cycle off with the equipment. A humidity icon will be displayed on the Fan Mode button when the blower operation is being inhibited due to high humidity. * The blower motor is not functioning. Check and repair the system.
