current temperature in the thermostat is wrong by 10degrees

[donsdndranch]

The current temperature in the thermostat is wrong by 11 degrees (too high) so, the heat won't come on because it thinks its 80 degrees when its 69 degrees. I can see there are many posts on this topic, but it says replies are disabled for this topic. I have reset the thermostat multiple times but the issue returns. Please note, I do not have the remote temp sensor, but I have one nest 3 downstairs (which doesn't have the problem) and a relatively new nest 3 upstairs that does have the problem,

I am about to return it but would like to try a solution(s) from the forum first.

Hi donsdndranch,

Thank you for reaching out. I understand that your Google Nest thermostat is showing the incorrect temperature. I know this can be frustrating, but please don't worry. I'm here to help you.

To better understand your situation, please answer the following questions:

• What type of Nest thermostat do you have?
• When was the thermostat installed?
• Where is your thermostat installed? (in a room and on a wall or stand)
• Do you have other active Nest thermostats? If yes, do they show the same issue?
• When did the issue start?
• Have you tried any troubleshooting steps?   Have there been any recent changes to your HVAC system?
• Have there been any recent power outages or power issues?

I look forward to your response.

Regards, 

Manuel
