Hi,
I'm hoping someone can give me an answer about my thermostat. For instance, the thermostat could be set at 70 degrees, with the room temperature at 64 degrees. Sometimes the furnace will not kick on. When it doesn't, I can usually rotate the thermostat setting down below the current room temperature, and go back to where it was set before, and the furnace will kick on at that point. Any ideas?

You seem to be describing a mechanical/mercury bulb thermometer. They can be very sloppy and can get worse with age. An electronic thermostat should solve the problem.

I thought the same thing. I had a mercury bulb thermostat last week. I went down and bought a honeywell t87 thermostat that no longer uses the little mercury bulb. It seemed to work better, but now it's acting similar to the old thermostat.:wall:
