I have a fan/light combo. The unit will not turn on with the light switch. Only the remote. Is there a way to bypass remote so light will turn on with switch?

Sure, you may need an extra switch lead, The lights wire usually goes straight up through the center of the pipe and connect to the receiver, cut the wire, cap the unused end, and connect the lights wire to your switched wire.
Remove the light kit and verify you are for sure on the Lights wire, usually blue or black/white.
Good Luck
