This is what I am thinking during the testing and thats why I am very confused.Your latest observation indicates that there's something seriously wrong with the triac or your circuit wiring. Triac with 100 to 500 ohm between A2 and G would effectively act as short and light the lamp continuously.
Did it. No luck.you can also try to revert the two triac anodes
I will share the wiring also. Unfortunately I forgot to click it today.Hi,
possible reasons:
* wrong triac wiring --> check wiring and / or post a photo of the wiring.
* the logic signal is too weak to drive LED and MOC. Either too low voltage or to low current --> try without the LED
* the CFL is too high impedance for the TRIAC to stay ON --> try an incandescent light bulb. If it works then try the CFL in parallel with the incandescent bulb.

The triac has A1 and A2 (com and out in datasheet terms) flipped. Can't work.
By the way, PCB clearance between 230V and control circuit is rather small.
Obviously. Read the datasheet and derive the correct circuit yourself.So you are suggesting to flip the com and out pin?
