GLAS Touchscreen Input Failure

The thermostat does not respond to touch or responds only intermittently; the display is lit but cannot be controlled.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

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

Possible Causes

Cracked or damaged glass, contamination or moisture on the touch surface, internal digitizer failure, loose display connector inside the GLAS

Safety: Do not pry open the glass panel; this can cause permanent damage.

Step 1 – Clean the screen: Gently wipe the screen with a dry microfiber cloth. Do not use liquids or sprays directly on the thermostat.
Step 2 – Remove any covers: If a screen protector or a decorative cover is installed, remove it and test the touch again.
Step 3 – Reboot: Remove the GLAS from the wall plate for 60 seconds, then reattach it.
Step 4 – Test different areas: Try tapping different parts of the screen. If only certain areas fail, the digitizer has likely been damaged.
Step 5 – Replace thermostat: Persistent touch issues indicate a faulty touchscreen assembly. Replace the GLAS thermostat.
