What to do:
Test the outlet by plugging in an appliance that you know is working,
for example, a lamp or radio.
■ If the appliance does not work, the outlet is faulty. If possible, plug the
control unit into a different outlet. Check the circuit breaker or call an
electrician.
■ If the appliance works, the wiring may be faulty elsewhere in the system.

charges may apply).
