on when the thermostat calls for heat? Does the hot surface igniter glow? Your furnace has an Electronic Fan Timer which delays bringing the blower on for either 30 or 60 seconds. For that to happen the combustion air blower must come on the pressure switch has to close and then the igniter glows and hopefully ignites the main burner. The next thing to happen is for the system fan to come on either 30 or 60 seconds later. Check this sequence and see what is not happening.
