The way the thing normally works, is that the thermostat will give a click, and the yellow "system" LED will light. This causes the furnace to light, and 10-30 seconds later you hear the muffled "whump" as the main burner kicks in. Then another 30-60 seconds(?) after that the fan kicks in.
(I know, you know all this... )
With my problem yesterday evening, the thermostat would give the initial click, but then immediately give another click, so what I'd hear would be "click-click". The display would blink at the same time, and then nothing would happen for about 20-30 seconds and then it would try again. (so the system light did NOT light up.)
thanks again, Al.
