Nest Learning Thermostat Display Assembly
The W5 error is a specific hardware diagnostic code signifying the failure of the internal Wi-Fi communication chip. This component is integrated into the mainboard's logic circuitry and is responsible for all network handshaking; its failure is typically due to thermal stress or manufacturing defects in the wireless radio module. A full replacement of the display unit is the only method to restore connectivity as the chip cannot be individually serviced.
