Nest thermostat is hot to the touch

Note: It is normal for Nest thermostats to feel warm, especially when the display is on. Excessive heat, discoloration, or burning smell is not normal.

• Check for burning smell or discoloration: If present, immediately turn off power to the HVAC system and remove the Nest display.
• Improve wall insulation: Seal the wire hole behind the thermostat with foam or putty to reduce heat transfer from the wall cavity.
• Dim the display: Lower the display brightness and reduce the time it stays on in Settings > Display.

If the thermostat is uncomfortably hot or shows signs of damage, discontinue use and contact Google Nest support for replacement.
