Ok so I know that wind and outside ambiant temps effect the temp on these things. But its 60 some odd degrees outside. Its taken me 30 min to reach 110* and now I'm dropping temp like a brick. I'm really new to this. Just very curious.
Sounds like your main heating element is not working. Make sure your vent is at least 2/3 open, unplug everything and re-plug it all. Make sure everything is seated properly. Let us know if this does not fix it. When these things are new, sometimes it is not as "plugged in" as you might think. Is your unit a digital?
