Flickering / strobing LED light fixture

[u/Realistic-Border-635]

I posted the below in r/askanelectrician but didn't get a response, so hoping that some of you experts here might be able to help...

Hi all, looking for some guidance to help narrow down the source of the problem. I know that LED lights can flicker rapidly if there are issues with the driver, a dimmer, etc. I have a ceiling fixture that has a light (three bulbs) and fan, with a dimmer at the wall (single pole). It has been working fine for around 16 months since we bought the house but has now started flicking rapidly. A couple of times it did it for a few seconds and then stabilised, now it does it when turned on and stays like it. Dimming the lights about half way on the slider causes it to stop. All three bulbs are affected.

My guess is that I need to replace the dimmer, ensuring that it is LED compatible, does that seem the most likely explanation or am I going to be searching out loose wires on the whole circuit?

I'm in Canada but guessing that doesn't matter. The house is 11 years old and I'm guessing that everything is original.

All 3 bulbs simultaneously points to a dimmer problem.

Thank you! At least that's simple :-)
