Ice Castle Heater Problem

[Grandee]

My heater in my ice castle won't shut off. If my batteries have a low charge could this effect the thermostat. Has this happened to anyone else. Thanks

unless you have a defective themostat------pull one of the wires on the t-stat and see if the furnace shuts down

Or if the wires are touching each other it won't shut off.

I had the same issue when I built my house. I found out that I stuck a staple through the wires and they were grounding out. Pull the thermostat wires at the heating unit and run completely separate wires to your t-stat. See if that fixes your issue.

Plus, note that when those units shut down, the fans run for a couple of minutes to cool themselves down. It should cycle completely off after that.

I second the fact that the fans run for a while after the heater kicks out. It might be that before the fans shut down the temp drops and the thermostat kicks the heater in again.

If the above suggestions don't work, try opening the window a little further, (I'm assuming that you are cracking a window for some fresh air, don't run your furnace without doing that) I found that if I open the window on the wall that the thermostat is on about 1/3 of the way the furnace regulates better and shuts off when it get's up to temp.

I also set my thermostat at 65 instead of 70 like I would do in my home. It still heats to 70 or so. When I set it at 70 the furnace runs constantly.
