I had a BROUN model 48V switch in the wall that had to paddle switches on it, one for the fan light and one for the fan motor. The switch failed and I bought a new double paddle light. The old Broun switch had 3 posts the bare copper earth ground was shoved back in the electrical box and the white wires are capped behind the switch. There are two black wires (one in the common) and a red wire.
The new switch has a blue post for earth ground and then two posts on each side. When I wire the red and a common on one side with a common on the other, only the fan works. If I switch the common wires from one side to the other, only the light works. What a I doing wrong?
