Quoted from rcbaughn:I would replace all the back box bulbs with LEDs so they don't overdraw that single circuit, and all would be well. Is this an appropriate route to take?
What makes this route superior to finding and fixing the problem?
You'll find a manual here: https://ipdb.org/machine.cgi?id=2509
Look at page 50-51 of the .pdf at the wiring diagram for the backbox.
