Question about Thermador HDW36TS Stainless Steel Kitchen Hood

I have Thermador HDW36TS range hood/fan with Elica motors S80-40ARP7701UL. There are three fan speeds. When the fan is on any speed the second speed light blinks continuously. Is this a signal that something is wrong? Please explain.

Wow, this is a situation, for sure. If the motor has a 3 wire system, the ground could be connected to the middle winding, and then both speeds would be the same. I would really check the wiring to the motor, as well as the switch. That's all I can think of, unless there is a crazy short, somehow.
