If the fan doesn’t spin up the sail switch will not do anything.

Good,luck with your endeavors

Thanks for the suggestions.
I already replaced the sail switch. The fan motor does not start at all now so it's something else I suspect.
I'm going to make a jumper to test the components. I read the single flash could also be the high limit switch which is in series with the sail switch. Just waiting for some time this weekend (I hate daylight savings time grrrrr.....).
