I recently purchased a 13' 2002 Trillium
Outback trailer (Yayyyy!) and I just came back from my first week away. I have a niggly issue with the furnace
(Suburban Model NT-12SE) in that although it seems to run just fine most of the time I found that when the outside temperature hits freezing, or close to freezing, it starts up automatically - even when I've set the thermostat to the "Off" position.
I thought with the stat set to off it shouldn't run at any time, regardless of the temperature? This only happens when it's really cold and I'm wondering if this could be a problem with the thermostat or possibly with the furnace
Since I store it during the winter I don't want the furnace
to run every time it gets close to freezing, so until I figure it out I'll have to disconnect the battery
Any ideas ? I was going to change the thermostat, but maybe there's another reason why this is occurring?
Thanks for any help you can provide
