Hello--
We just replaced both limit switches and the control board; green light is not illuminated. Does anyone have any thoughts? The fuse is fine, and the blower works.

Thank you so much for your help.

No power to the board. Double check all your connections on the board.

Still no luck. Is there a diagram of the connections?
Thank you.

We've checked and re-checked the connections. I can get the blower to run by switching connections. Still no LED. We are wondering if the transformer could be causing the problem. Is this possible?

Did you verify power coming into the board with a meter?
