I have 5 LED-based recessed lights on a 3-way switch that are problematic. When I activate the circuit, I rarely get all 5 lights switching on. If I turn them off and back on again, they all work.
They don't come on or go off, whichever ones switch on, remain on. There is also no pattern to which lights come on -- anything from 1 to 5 can come on, and not necessarily in the wired sequence. I have 20+ fixtures and they're all fine, including some installed on another 3-way.
Any tips on where the fault is, or troubleshooting, or do I simply need to replace all the cabling?
