Thermostat buttons or touchscreen are unresponsive or respond erratically

Safety first: Do not pry open the thermostat; internal components are delicate.

Steps to restore UI responsiveness:

• 1. Clean the surface: Gently clean the touchscreen with a soft, slightly damp microfiber cloth. Avoid harsh chemicals.
• 2. Reboot thermostat: Remove the thermostat from the sub-base for 30 seconds, then reinstall to reboot.
• 3. Check for physical damage: Inspect the screen for cracks or impact marks. Physical damage usually requires replacement.
• 4. Use app as workaround: If available, use the Goodman app to control the system while planning thermostat replacement.
• 5. Replace thermostat: If the touchscreen remains unresponsive, the touch panel or controller is likely failed and the thermostat should be replaced.
