I know, that's why I said about replacing the dimmer with a solid state speed control, instead of an on/off switch. Lights are safe for solid state speed controls, but fans are not safe for dimmers. And if they're going to be on a same switch with a light, and they have to dim the light, the fans can't have 16 pole motors, which is why I said about replacing them with Originals. Solid state speed control are safe for Originals, but not for 16 pole motors.
