    Dear Alex,

    D14 output is High side switch, so that means it doesn’t go to zero and you shall have significant load for proper operation.

    Also PWM can be problem with inductive load types without freewheeling diode.

    What type of load do you have please? 1kOhm in parallel to dimmer can work. What exact type of dimmer do you have please? If it has analog input, you shall have some rectification also to the dimmer.

    Thank you !

    BR
