    Pro Dimmer/LED Cans lost control until I reset breaker

    Hi,

    Firt time poster. We are a new build with about 25 devices all Pro Dimmers and a few plug ins for lamps.

    All has been fine except today in my office I have a dimmer connected to 4 Halo RL56 cans which wouldn’t turn on. The dimmer looked like it was working and Alexa thought she was controlling them but no lights. Every thing else seemed to have power in the room.

    Not knowing how to trouble shoot I reset the breaker (arc fault) and all was fine... Any thoughts ? Has anyone seen this before? Any other troubleshooting I could have done before hand?

    Thanks

    If it happens again, I'd replace the dimmer

    Make sure the power is coming in on the black and out on the red.
    Make sure the neutral is connected. Not all white wires are neutrals. Some electricians read the instructions as the neutral being optional. It is not.
