AC Dimmer Circuit

soldar:
A faulty/scratchy pot is going to give a flickering light output as it turns and will be obvious as to being faulty in that manner.

Also, if the pot is under suspicion you can just short it with a piece of wire.

Zero999:
That's a good idea: replace the potentiometer with a wire link and it should pass the full current. Cut the wire link (preferably with the power off or with properly insulated cutters) and it should be off.

coppercone2:
careful i think there exist pots with a minimum resistance that is specified

and it might only go down to like 15 ohms rather then 0 ohms if its made poorly... i don't really remember how good they are.

maybe try a reasonably small resistor in comparison to the pot or find the pots specifications to make sure

soldar:
coppercone2, in general I find the quality of the content of your posts leaves quite a bit to be desired. And the presentation would improve if you used the shift key when appropriate. Or is it broken?

In Vacuo Veritas:
He's quite the nutter for sure, but at least he doesn't think he knows better than GE what "triac" stands for.
