Why does my American Standard ACONT900AC43UA indoor temperature display show dashes?
If the indoor temperature display on your American Standard Control Panel shows “--”, it indicates that the indoor temperature sensor is either open or shorted. Replace the control.
What to do if my American Standard Control Panel says Heat ON or Cool ON, but there is no air?
If your American Standard Control Panel indicates “Heat ON” or “Cool ON” but no air is coming from the registers: 1. **Heating Equipment Delay**: Wait one minute after “Heat ON” is displayed, then check the registers, as some systems delay fan activation until the furnace warms up. 2. **Equipment Malfunction**: The heating or cooling equipment may not be operating. Check the heating and/or cooling equipment.
Why is my American Standard Control Panel only using furnace heat in Dual Fuel mode?
If your American Standard Control Panel is only using furnace heat in Dual Fuel mode, it could be due to: 1. **Outdoor Temperature Sensor**: The outdoor temperature sensor might be missing or not reporting. Check and repair the sensor field wiring. 2. **Compressor Lockout Temperature**: The outdoor temperature could be below the Compressor Lockout Temperature setting. Lower the Compressor Lockout Temperature setting if desired.
