I have a two switch plate & installed a ceiling fan using dual switch instruction (white/white, black/ungrounded, blue/ungrounded). Fan & light work fine from one switch, but I learned second switch is for a wall outlet, not the ceiling. Do I have to rewire it for single switch (white/white, black & blue to black ungrounded) or is it fine?
This doesn't make sense:
"Fan & light work fine from one switch...... Do I have to rewire it for single switch "
Do you mean they work fine from there respective switch? If so then your OK to leave it as is. Just remember that the outlet is also controlled when the fan (or light) is on.
