Thermostat screen is on but unresponsive to touch or button presses.

Safety first: For low‑voltage devices, risk is minimal, but avoid opening the unit while powered.

• Step 1 – Clean surface: Wipe the thermostat screen with a dry, lint‑free cloth to remove moisture or grease that can interfere with touch detection.
• Step 2 – Soft reboot: If available, hold the power or menu button for 10–15 seconds to force a reboot.
• Step 3 – Hard power cycle: Turn off power at the breaker for 1–2 minutes, then restore. Check if the UI responds.
• Step 4 – Firmware update: If you can access the app, trigger a firmware update, which may fix touch controller issues.
• Step 5 – Replace front panel: If the display lights but never responds to touch, the touch panel or controller IC is likely defective. Replace the thermostat front/user interface module.
