I moved into a home with a 15 yr old Carrier Gas Furnance Model A78482. When I turn it on for heat it sometimes, not all the time, sometimes will try and fire and and makes 20-30 clicks until it ignites. Then once it ignites and the blower goes it stays on for 30 seconds and system shuts down. Is this a bad ignitor?
