My furnace seems to be working but when the thermostat reaches the desire temp set (new honeywell digital from a Lux) an shuts off it will not restart on its on, I have to restart it by flippin on the switch on the furnace to restart it. I'm not sure what the problem is, but some times just flippin the switch, the furnace will start but shuts off after a few minutes not even heating the house. Please help!
