Okay, all you problem solvers out there, here's your latest puzzler: we just spent the Labor Day weekend in Glacier Park, just up the road from us about 4 hours. Spent the first night in St Mary Campground where they take reservations and then hotfooted it over to Many Glacier to grab the first available site we could get. Saw both a bull and a cow moose while there. Beautiful and wonderful, as many of you know. Truly, one of our national treasures.
Anyway, here's the issue. The 2nd night there, it dipped down to 26°F. We like it cool; it's great for sleeping. So it surprise us, however, when the furnace came on about 2 AM. I checked the thermostat and, yes, I did have it turned off and the temperature at the lowest setting.
So, I clicked it on and off again. After a minute or two it turned off, as expected. Then, about an hour later, it turned itself on again! Once more, I checked and verified that I had turned the thermostat to the off position. Once again, I clicked it on and off and a few minutes later, the unit cycled off. You can imagine our dismay when it started again about an hour later. At 5 AM, I considered getting out of bed and turning the master switch on the furnace to the off position but I didn't think it was worth it by then.
So what's going on? Why, even with the thermostat in the off position, does our furnace continued to cycle on? Admittedly, it was cold. But it shouldn't have a mind of its own. There are many parts to that thermostat, after all.
Any ideas out there?
To everything there is a season ...
