Red wire on 3 way tripping breaker
I replaced a ceiling fan/light combination. Two wall switches controlled the original light without issue. From the switch I had a ground (bare), a white (neutral) and a black and red (hot) wire. I connected, from the fan/light, the green to ground, white to white, black to black, and blue to red. The fan wold work fine but when I turned the light switch on it would trip the breaker. I switched an paired the black to red and blue to black and when I turned on the fan it would trip the breaker. So both time the red wire connection caused the breaker to trip. I disconnected the red from all fan/light wires and put a wire nut on it so it wasn't risking connecting with metal anywhere in the fixture. I connected both the blue and the black on the fan/light to the black wire from the switch and now the fan/light both work off the switch but when I turn on the stubbed off red switch the breaker trips. I can safely assume that there is something askew with the red wire and would like to look at how to fix that. Is this something as easy as checking the red wire at both the switch and within the ceiling mount or will I need to get an electrician in to run a new red wire?
