I replaced three existing fan/light controllers with MACL-LFQW. One of them works just fine. Two of them are in bedrooms with identical small fans that have compatible Cree dimmable LED bulbs. I know they are wired right because they will turn on the fan and light. However, if I turn on the fans, after the fan comes up to speed, the switch cycles between on and off for both the fan and the light. Can two switches on the same circuit breaker interfere with each other? When I installed the first one, it seemed to be fine. Then after I installed the second this ghost in the machine stuff started happening.
