Heater blowing cold air when heat set is on

[Bluminicoop]

Lately my heat blows cold air when set to heat. FYI I do not have AC. I have found that if I turn the nest off or reset. The heat works fine but recently has started to revert back to cool. It is 20 here in Boston and I do not need this problem right now.

Hi everyone,

In an effort to keep content fresh on the forums here and prioritize current issues, I'm going to go ahead and close up this thread. If you have any outstanding issues from this post or any other problems, please feel free to open up a new discussion. A good place to start on this one is to check the heat pump system. We have a reference article for that found here: https://bit.ly/3o6pPh6. If you're still having issues, try posting a thread with more details or contacting support directly.

Thanks,
Jeff
