Arrived on the job site and the customer stated that two outlets on the garage/outdoor circuit were not working. I inspected the GFCI and found it in critical condition. The low side showed blue and orange discoloration on the brass terminals, indicating overheating or a loose connection causing arcing. I replaced the GFCI and also noticed that one of the lines had not been connected, so I reconnected it properly. After reinstalling everything and restoring power, all outlets were working correctly. I also observed that the customer has several items on this circuit, including Christmas lights and a freezer, but none of them are overloading the circuit at this time. The customer understands that the new GFCI outlet comes with a five-year warranty and is 100% satisfied with today’s visit.
