The dimmer knob that controls the fan and lights in my bedroom has stopped working, after months of decline. Ideally I'd like to replace it with a simple switch. All the "how to" videos seem to be about doing it the other way, going from a switch to a dimmer, so I figure I'd reach out to the experts here. No idea if seeing the knob helps but I've attached pictures. Just to clarify: It used to be the knob was in the off position if you turned it all the way clockwise until it clicked. Then when you turned it counterclockwise just past the click the lights and fan would turn on. If you kept turning it they would dim (a ceiling fan dimming is really just a ceiling fan that makes a lot of noise) so we pretty much always turned it back clockwise until just before the click. As the thing declined, only that "just before the click" position did anything and all other positions were effectively "off", and it got harder and harder to get it right in that spot because it was real fidgety. Then today there was no click no matter which way we turned it, just off.
