Leviton Trimatron Rotary Dimmers
Replacing a Push On/Off Dimmer Switch should be easy.
According to the instructions,
Connect wires per appropriate WIRING DIAGRAM as follows: Twist strands of each lead tightly together and, with circuit conductors, push firmly into appropriate wire connector.Sounds reasonable, until you look at the wiring diagram which shows a BLACK and a WHITE wire coming out of the dimmer switch.
Funny, mine has TWO BLACK WIRES coming out of it!
After consulting the neighborhood expert on the subject, I followed the existing installation and attached the RIGHT and LEFT wires where they were connected to the old dimmer switch.
I ran down to the basement, with This Old House anticipation, to turn the power back on.
When I returned up stairs, I pushed in the dimmer switch and the lights went on.
Success!
Now we have to clean the light. It looks dusty.
