No the original was the fan and light was on a separate switch a two gang switch so I’ve swopped the switch new for old then I’ve even put the old one back on and the same think but the light and fan come on together
Swopped them both to L12 and L22 same result even put the old switch on same thing happing I’m thinking it might be the loop between the two com
no only by switching the light switch witch is controlling the light and fan now together
