Check low voltage switch for pilot light for fireplace. And also check the plug in the fireplace and I had 120 V on the plug. Could not locate the transformer, feeding the fireplace and explain to customer that he will have to get a fireplace guy out to look at the fireplace and see why it’s not working properly. It was not the electrical though for what I was allowed to work on and was all something to do with fireplace. Customer also had multiple lights throughout the house some in the bathroom, kitchen area, pantry, living room, and other places that were not working properly. Customer also had a sprinkler system, and compressor in the AC unit and a couple other items that went bad. Explain to customer he was 100% hit by a surge that fried all of these lights, fireplace, and other items. Customer is going to replace the light fixture himself and highly recommended. He gets a different search protector on panel.
