Hi, I have a two year old Learning Nest that all of a sudden will not read the correct room temperature. It now reads 5-6 degrees hotter than a normal thermometer sitting next to it. Has been working well up to this point. I can not think of a thing that has changed. I was thinking of resetting to factory specs and starting over. Any thoughts?

The Nest learning thermostat has multiple temperature thermistors located in the faceplate. It uses these to determine the ambient air temperature around the thermostat. Thermistors do not drift, they very accurate and either work or they fail completely.

Hello folks,
I wanted to stop by and see how I could help.

Hello,
Thanks for responding to my post. I did chat online with a Nest agent who did suggest your fixes. I did the 24hr offline and then did a restart, which seems to have fixed the problem. I also cleaned the surface of the Nest as per instructions and I reduced the size of the hole behind the Nest where the wires come through the wall to reduce any air intrusion from possible leaks. I sent pictures to the agent I talked to and I am sure that Is why they gave me the possible fixes you gave. Thanks

Hello Corbin123,
Sounds great! Thanks for trying to find a fix by reaching out to our support team via chat. What happened was that some wireless access points can cause the Nest Thermostat’s Wi-Fi chip to overheat, which affects the ambient temperature readouts.
Please check out these articles about the Wi-Fi routers that are incompatible with Nest products and the recommended Wi-Fi router settings for Nest products to ensure that there have been no changes made. Also, try reconnecting it to your Wi-Fi network and keep us posted if that helps, or if the issue still persists.
Thanks,
Mark
