Troubleshooting Steps for Nest Thermostat

When your Nest thermostat doesn’t activate the heat pump, follow these troubleshooting steps to resolve the issue quickly.

Check Power and Connectivity

Ensure your thermostat is receiving power. Check the display; it should light up when you touch it. If the screen is blank, inspect the circuit breaker for tripped switches. Power interruptions can occur due to severed wires.

Verify Wi-Fi connectivity. A stable connection is crucial for remote control. Open the Nest app, and confirm your thermostat shows a green status indicator. If it shows as offline, reset your Wi-Fi settings.

Inspect Thermostat Settings

Verify the thermostat settings to ensure the heat pump is correctly selected. Open the Nest app, go to “Settings,” and check that your heat pump is set as the heating source.

Review the heat pump settings. Some systems require configuration for specific modes, such as “heat pump” instead of “furnace.” Adjust these settings as needed to ensure proper functionality.

Check the “Emergency Heat” mode. If this is engaged, it might prevent the heat pump from operating as intended. Turn it off for regular heating unless necessary.
