Steve,
So as an electrical engineer that worked when there were a lot of potwntiomers (pots) used, The pot is the weak point in any design that employs them. They are usually a carbon emulsion on some plastic base. They have problems over time. Tapping them or slightly moving them re-establishes connection. Pulse Width Modulation (PWM) controls can go out of range with bad input. The result could be zero pulse width, which could be off to some displays. However, like the engineer said, if voltage from the E-lite module is bad, it'll go off too. These are all just places to look. If it is flickering, check the voltage on AC, assuming you have a meter that reads auto ranging frequencies or an oscilloscope.
Regards,
Bob

Thanks for the pro tips, Bob! Sure hoping to drill down and squish this nasty bug...and with all your help, I'm betting I can!

Jim Scott said to hook that dimmer up to a battery source to test it. But, I didn't see how that would be enough since that E-line power supply is 240V output!  I think Jim was confused, and when I tried to clarify, it seemed to make things worse.

I wanna get to that unit and test/tap it, because I completely know and agree with what you are saying about Pots going bad. Being an electronics hobbyist gave me enough (bad) experiences in the audio world with those suckers causing noise.

Thanks again!!
