Hello, I have an 80MGF3-75-3 the circuit board was shorted out. Replaced the circuit board, and the electrod ignitor. When the call is for heat, the blower motor comes on, and there is a strike for spark, but no spark can be seen, and the hearter refuse to light. After four tries the shutdown mode kicks in and there is a contious blinking from the red to the green.
