Lightning damage to my Bryant, I need help fixing it.

[paulmars]

My computer and a dimmer on a ceiling light both got fried. These are
on different circuits and so is the AC.

Shortly after the hit I noticed the central unit fan on. The
thermostat was set to auto and ac/heat switch was set to off. So, i
pulled the fuse. 4 days later I plugged in the fuse, and after a delay the fan operated, as it did the night of the Lightning strike.

I removed all four thermostat wires from the circuit board in the AC unit and the fan still turns on with the fuse in(after delay).

I suspect its that circuit board, but want to be sure before I take it
out. There are two relays mounted to it.

Ideas?

It sounds like it would be your board. It sounds like your points are welded together in the relay that runs the blower. There may be other damage but sounds like you need the board. Later Paul
