I have a rooftop 1983 Carrier heater/AC model 48KLA136---300BE. The heat wont come on. I went on the roof and opened the side panel. The igniter is on and there is a small flame, but the burners wont come on. It is making a loud electical buzzing noise. I unplugged the spark plug type boot from the ignition control box and the buzzing stopped. When I plugged it back in the heater would come on and the buzzing would stop. Now it wont come on when I do that. Any help would be greatly appriciated. Thanks
