Hi do you have a test light or voltmeter to do some testing? thanks
thanks, there is something you can do without testing, does your furnace have an exterior door or cover to remove for access to the components? some do some do not
you really need to test to see if there is power getting to the control board thru the ignition circuit, the only thing you can do without testing is unplug the connector on the control board, clean the pins on it, and replug. I am giving you the service manual for your records
another clue we can have is look at the control board when the furnace has failed, and there is a red led light on it, it will flash a fault code, count the flashes, and pauses, then let me know what it tells us..thanks
