Heat turns on but stops short

Our thermostat seems to kick the heat on but then it often stop short of the set temperature. We can usually get it to kick back on by turning the heat down and then back up but the thermostat consistently stops heating before it has reached its desired temperature. The heater seems to be working just fine and wondering why toggling the thermostat keeps getting it to work.

Here are some possible solutions:

Check the Nest app settings:
Make sure your Schedule is not lowering the temperature at certain times of the day.
Turn off Auto-Away if it is on, as it may reduce the temperature when it detects no activity.
Inspect the thermostat:
Ensure there are no air vents or other objects blocking the thermostat.
Confirm that the Nest is mounted level and firmly on the wall.
Restart the Nest:
Press and hold the ring and rotate the thermostat clockwise until it reboots.

Check the system:

Clean or replace your air filters if they are dirty. Dirty filters can affect the airflow and heating efficiency.

Hello folks,

I wanted to stop by and see how I could help.

Thanks for the input, steve81uk.

@Foxmatt, it sounds like you're dealing with a bit of a thermostat mystery. Situations like this are usually caused by power-related issues. There are a few things you might want to check to troubleshoot the issue.

 

  1. Make sure that your Nest Thermostat is programmed correctly. Sometimes, discrepancies in the programmed schedule can lead to unexpected behavior. Double-check the temperature settings and schedule to ensure they align with your preferences.
  2. Ensure that your Nest Thermostat has the latest software updates. Occasionally, outdated software can cause glitches. You can check for updates in the Nest app or on the device itself.
  3. If your Nest Thermostat relies on batteries, ensure they are in good condition and have enough power. Low battery levels could potentially cause irregular behavior.
  4. The thermostat's sensor might be in a location that doesn't accurately represent the overall temperature of your home. Make sure it's not exposed to drafts, sunlight, or other factors that could affect its readings.
  5. Confirm that your heating system is fully compatible with the Nest Thermostat. Some systems may require additional accessories for optimal performance.

 

In the meantime, your workaround of toggling the thermostat seems to reset it temporarily. While this may not be a long-term solution, it could be an indicator that there's a communication issue. Gather the power readouts in the Equipment settings or in the Technical Info settings.

Let us know how it goes.

Best regards,
Mark
