Nest Thermostat thinks its 0 degrees all the time

[Ruth157]

My Nest Learning thermostat is constantly showing the actual temperature as 0 degrees. So whenever its switched on it heats the house like mad and never stops. 

I have tried restarting it and also a factory reset and the problem persists. I am assuming the internal temp sensor is broken or possibly a software issue.  Can anyone help me with suggestions of things to try or advise how I can get in touch with Nest if this is a technical issue.

Hey @Ruth157,

• Thank you for reaching out! I'm sorry to hear about this issue, but I'll do my best to help you fix it. 
• Can you first tell me what kind of thermostat do you have? 
• What country are you based in? 
• Also, when did this issue start? Were there any power cuts in your area? 
• Have you recently had service or maintenance on your electrical, plumbing, or heating system?
