If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Safety: Turn off HVAC power at the breaker before removing the thermostat from the wall.

Reboot: Turn off power for 2–3 minutes, then restore and test the touchscreen.
Clean screen: Wipe the screen gently with a soft, dry cloth. Do not use harsh chemicals or excessive moisture.
Reseat thermostat: Remove the thermostat from the sub-base and reattach it firmly to ensure good contact with the connector pins.
App control: Use the American Standard app as a temporary workaround if the screen is partially unresponsive.
