Default A faulty light fixture?

Hello all,
Just hoping to get some advice perhaps. Yesterday I was installing new LED light bulbs in a ceiling fan. It seemed to work great for a few minutes then turned off and on then stayed off. I first thought it would be a tripped breaker perhaps however it was not. I next thought a loose wire either on the switch or in the fan, it seems to be neither. I am going to try a new switch today to see if that does anything however if not does anyone here have any other suggestions?
the rating plate is for 60 WATT bulbs which I got, however it also said incandescent, I haven't known any fixtures not being able to take LEDs.

Sometimes those fans have a watt limiter built in so the led may be causing issues with that item.

Hmm if that were the case then putting in the old bulbs or even having no bulbs would turn on the fan at least yes? I tried but if anything it seems fried.

So a 60watt incandescent will work but not a 9 or 13 watt LED?

Never seen that before.

I am hoping it is just a fault in the switch but who knows.

I see you say you're an apprentice, don't be a parts changer.

Do you have a Wiggy or other load type circuit tester?

Take a reading on the voltage in and out of the switch, check for voltage with a meter at all connections.

Know where you do and don't have voltage.

Curious, why ask here rather than ask your journeyman?

It has to do with the current limiter that is attached to the socket. By-pass the limiter and you'll be okay but UL listing is voided. Have I done it? (Head down_) Yes

It has more to do with the electronics in the LED somehow messing with the current limiter

You probably blew out the current limiter-- incandescent only means something in this case

I did, he suggested that I change the light back and forth, try with and with out the lights. Make sure to turn the breaker on and off, make sure all wires are tight within the switch and in the fixture. I have done all the above to no avail. I have already given up on the fixture and am now just trying to figure out what could be the cause. As for the circuit tester I did try to get a reading last night but didn't have much luck with getting a reading. I plan to try again before I change out the switch.

What are you using for a tester/meter?

Not so sure it has to do with the quality. There was a period of time where they were used and it may have been just one company, IDK however I have run into it a few times

Would a faulty limiter cause the whole assembly to stop working even after removing the LEDs?

That should be fine for reading the switch and connections up stream.
