Keep them…you’ll need them as spares for replacement. I have one that low and medium fan speed has died on it. Don’t get me wrong, I’ll likely replace it whenever a new one comes along, but I’ve seen so many complaints about the low/medium failure. Maybe that’s one of the things Eric was referring to the manufacturer would not fix.
FWIW, all of my fans have the three speed switch still in place, and we really don’t change the speed from low on any of them. If the canopy module’s low/medium failed, I would just set the LZW36 to high and use the fan’s speed switch. The light control is more important to us…
