Did you find a fix for this? Mine has been doing this now and my temp
outside is 2 windchill -30. I can’t get the house to get past 67. Wake
up today to 64
Same!! Google is about to get my heat bill. Because it won’t shut off
but it’s not warm. My bill is going to be outrageous. I keep turning it
off and on and seems to help for a bit.
