I have replaced a 2 gang dimmer switch for 2 sets of lights with a new switch, but the internals for the new switch are different. I have wired it up and both sets of lights work and dim OK, but after a while the switch heats up and one set of lights cuts out. After a while it cools and the lights come on again. I have connected Yellow to L1 on the first gang, and Blue to L1 on the second gang, Red to C on the second gang, and connected C on both gangs together with a short piece of cable from a 3 core standard flex . Where have I gone wrong? Any assistance appreciated.
