I’m trying to install a set of light switches to control my fan and lights. The left switch has two black cables running to it and the right has a red and black.
I installed both switches and the left doesn’t power on when I flip the breaker. I’ve confirmed it isn’t a manufacturing issue with one of the switches by uninstalling/reinstalling them in the reverse order. In both cases, the left side is the one not receiving power.
Below are the original and new configurations, respectively:
The new red wire on the left connects to the nest of black wires similarly to the original bottom black wire. I’m afraid what may happen if I reverse the wires going to the red and black on the left switch, though I don’t know whether that will do any actual harm.
Any clear issues with how I rewired these?

You need to reverse the line and load on the left switch
