    Hi Dinah, The power source in the bathroom switch box should be tested for normal power and inspected for a possible faulty wiring connection to a switch or a faulty wire splice of ether the power or the neutral wire.

    The lights and exhaust fan in the master bath will not turn on. The outlets work, half the master bedroom is on the same circuit, and everything is working there too. I went through all the circuit breakers. We haven’t done any electrical work recently.
