Thanks for the responses. I'm not leaning towards propane, because I can smell it, actually I'm surprised by the amount of propane I smell. It has been below freezing the past few weeks, and I know propane can get strange when it's cold.
I'm thinking there is no flame, wouldn't I hear it even if it lit for a few seconds? I thought it was odd that it didn't fire with the cover on, I'm thinking that was just coincidence, cause I couldn't get it to fire with the cover off again, it had been running intermittently. The back of this unit is a real PITA to access it's in the basement behind a wall that has to be removed.
The high tension wire is the red one that runs from the circuit board to the electrode, correct?? And what exactly makes the clicking sound? Thanks
