hello,

I have a hunter thermostat 4155c. It's been working fine for over a year now. However, recently my furnace stopped automatically coming on. If I turn it on it will come on, the fan will blow. Also if I shut it off and turn it on it will come on automatically x1 then no more. Is it my thermostat or do I need my furnace checked?

Since the thermostat controls the furnace and the furnace runs I would suspect a thermostat problem.

Give a simple check of the furnace or thermostat.
