Thermostat display is on but unresponsive to touch or buttons

Safety first: No need to open HVAC equipment; work only at the thermostat.

Steps to troubleshoot:

• 1. Reboot thermostat: Remove the thermostat from the wall plate for 30–60 seconds, then reattach to force a reboot.
• 2. Clean screen: Wipe the screen gently with a soft, dry cloth to remove oils or moisture that may affect touch sensitivity.
• 3. Check for screen protector: If a thick aftermarket screen protector is installed, remove it and test touch response again.
• 4. App control: Try adjusting settings from the Resideo app. If the app works but the screen does not, the touch panel is likely faulty.
• 5. Factory reset: If you can access menus, perform a factory reset to clear any software issues.

When to call a professional: A persistently unresponsive screen usually requires thermostat replacement.
