I recently installed Leviton motion activated light control on two light circuits. One has 3 CFL lamps the other 6, both on different circuits. I noticed flickering when the lights were off and the switch in the auto position. When the lights were on, switch in the auto position, my microwave oven, on a separate circuit, hums and shuts off after running about 10 seconds with timer set for 2 minutes. I discovered that this control shouldn't be used with electronic ballasts, after reading the instructions!! When the light switch is in the off or on, not auto, everything works normally. I replaced only 1 CFL with a standard incandescent in each light circuit and everything works normally, no flickering and microwave works.
I think that the switch has a little bleed through current so that the infrared motion sensor will work, that probably explains the flickering. Why when replacing only one CFL with an incandescent bulb everything works normally?
What is causing the microwave to react this way?
Will the incandescent bulb installed in each circuit create a potential hazard?
