What are the status codes that flash on the LED on a system that will not turn on.

red light that is burning on your circute board,,or control moduel,,,if its coding it will flash,,,not all furnaces have one,,,if you have one but its not burning you have a prob. check fuse in board,chech main power,,,,it should have a glued on paper on inside of door/panel that tells you what the code is

Thanks. I did find the direction on the panel in plain site after I ask this question.

Thanks
