New ceiling fan install worked--until I attached blades
Replaced an old ceiling fan/light combo with a new Hampton Bay unit. After attaching wiring and securing the fan motor to the support bar, I flipped the wall switch and tested the pull chains; both fan & light worked fine.
But after attaching the motor housing, fan blades and glass lamp shade, neither fan nor light will turn on. Circuit breaker is fine, and I don't think I did anything to compromise the wiring, but I can't figure out what the problem is. Are there any common ceiling-fan tricks or traps I don't know about?
