Why is my American Standard Control Unit fan not running when set to ON?
- DDeborah KellySep 8, 2025
If your American Standard Control Unit fan is set to ON but not running, the Smart Continuous Fan feature may be 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 too high humidity. If the humidity is not the issue, the blower motor may not be functioning; check and repair the system.
