Hi @Divotnaz72!
Thanks for posting in the community.
I’m sorry to hear that your Nest thermostat is not heating and also not turning on the fan.
To assist you with the best solution, I would like to get a bit more information:
- Can you tell me more about how often this is happening? Is it random, or does it seem to follow a specific pattern?
- What type of Nest thermostat do you have?
- Are there any error messages? If so, what are they exactly?
- When was the last maintenance check for your HVAC system?
- Have there been any recent changes or upgrades to your HVAC system?
- Do you have a common ground wire or C wire?
- Does the issue happen on heating only, cooling only, or both?
I’ll be waiting for your response.
Regards,
Daniel.
