  • Replace The Nest Thermostatโ€™s Battery:

If your Nest Thermostat battery isnโ€™t charging, its batteries are probably draining out. And replacing the batteries is one of the best solutions to battery charging issues. If you see a low battery indication on your thermostat, it means itโ€™s time for you to replace the Nest Thermostat battery and insert new batteries. If you donโ€™t know how to do that, have a look at these steps:

Change The Batteries OF NEST Thermostat

  1. Pull out the Nest Thermostatโ€™s display.
  2. Take out all the low/dead batteries and throw them away.
  3. Insert new batteries into the battery slots.
  4. Place your device back in the display.

This will quickly fix any issue with the Nest not charging on base.

  • Check For Loose Or Damaged Wires:

If resetting your thermostats doesnโ€™t fix the charging issue, then the issue is in the HVAC system rather than in the thermostat. Your Nest batteries are charged from the HVAC system and this power flows through the wires in the base.

Open the base of your thermostat and see if there are any loose or burned wires or if any of them are damaged. If yes, your thermostat wonโ€™t get enough power supply to charge the built-in battery.

Loose wires may affect the flow of current to the batteries which affects the charging. Fix the wires, tape them properly or call any technician to solve the issue for you.
