Hello all~ I have a Carrier WeatherMaker 8000 & it is turning on by itself even though the thermostat is NOT sending the turn-on signal. When this happens, the flame does NOT come on nor does the main fan come on... but instead just the pre-stage fan blower. The duration is 5-10 seconds & the frequency varies from 3-20 times/hour. Also, there are NOT any error codes flashing. Any help would be greatly appreciated! Thanks~ Joey
