Why is my American Standard Control Unit heating not working?
- Ddanny82Aug 20, 2025
Your American Standard Control Unit may not be heating because the system mode isn't set to Heat/Auto, or the setpoint is too low. Set the mode to heat and raise the setpoint above the room temperature. It's also possible the minimum off time delay is being enforced; wait 5 minutes and recheck the heating equipment. Finally, the heating system itself may require service, so check and repair the system if needed.
