Question about Heating & Cooling
Your control board may have a problem. When the burner fires up, after a time delay of about 45 seconds, you need to use a voltmeter and see if the terminal marked H for heat has 120 volts coming off it. This voltage will be the power to spin the blower. If ther is 120 vac at terminal H then the blower motor or cap. is no good. If there is no 120 vac then you may have a bad control board.
