How to Fix / Troubleshooting

Safety: Turn off HVAC power before removing the thermostat to avoid wire shorts.

Remove thermostat: Gently pull the Nest display off the base.
Tighten screws: Tighten the base plate screws into wall anchors or studs. If the wall material is weak, use appropriate anchors (e.g., toggle bolts for drywall).
Level and align: Ensure the base plate is level and flat against the wall so the Nest can seat properly.
Inspect clips: Check the plastic clips on the base that hold the Nest display. If broken, the base plate should be replaced.
Reattach thermostat: Carefully push the Nest display onto the base until it clicks and sits flush.

Nest thermostat base plate is loose or thermostat does not sit securely on the wall
