Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Thermostat not turning on. | Check if the main power to your heating system is on. Ensure the Nest display is properly seated on its base. The internal battery might be completely drained; allow time for it to charge after re-seating. |
| No Wi-Fi connection. | Verify your Wi-Fi network is active. Check Wi-Fi settings on the Nest thermostat and re-enter password if necessary. Ensure the thermostat is within range of your Wi-Fi router. |
| Heating/Cooling not responding. | Check the mode setting on the thermostat (Heat, Cool, Off). Ensure the Heat Link is properly connected and powered. Verify wiring connections at the Nest base and Heat Link. |
| Temperature readings seem inaccurate. | Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources (e.g., lamps, electronics) that could affect its internal sensor. |
| Thermostat not learning schedule. | Ensure the "Learning" feature is enabled in the settings. Make manual temperature adjustments consistently for a few days to help the thermostat learn your preferences. |
If problems persist, consult the comprehensive troubleshooting guides on the official Google Nest support website or contact customer support.
