Report "I have two of these switches and they both are operating incorrectly. I use them to control bathroom fans in two separate bathrooms, but they both act the same. That is, when I push one of the time settings they provide only enough power to the fan to barely make it move. When I take the switch out of the equation and hook the two black wires up directly to each other the fan works at full speed. Are these faulty switches or do I have something wired incorrectly? (I can't imagine I have it wired incorrectly since I simply replaced the existing switch with this new one and attached the green ground wire to the other ground wires.) Help!"
