I have a MACL-153M and a MA-L installed in a staircase. There is one ceiling lamp with a incandescent bulb. I used a multimeter to ensure the wiring is correct.
- If I (try to) switch the light on using the master dimmer, the bulb goes on for about a second and then goes off. However the indicator LED on the master dimmer stays on.
- If I (try to) switch the light on using the companion dimmer, nothing happens except that the indicator LED on the master dimmer goes on.
I changed bulbs and tested the wires but can not find the reason for this problem.
Anyone any idea?
