The temp changed outside to minus weather and it rained. In the middle of night furnace shut down. This happens alot. We keep turning the furnace off and on. sometimes it fires. Does this problem have anything to do with the relative humidity setting in my bathroom.?????? I can not find any info on how to set this to work in different weather......????All I wanted was a furnace I could set at 70 degrees and it heats the house this furnace has been a pain since new shutting down when I really need HEAT.
