Arrived on site to troubleshoot garage door not working and entry hall lights not working. The garage door outlet had faulty connections. The outlet was backstabbed causing the connections to become loose over time. I remade the connections and the garage door is now working as it should. We checked the switches in the entry hall. The hall lights work intermittently. These switches are the deako rocker switches. These are known to not make good connections. I recommended to the homeowners to replace these switches with standard decora style switches. We also noticed a burn mark on the main electrical panel. This is a QO panel. I recommended we replace the internals of the panel with a new bus bar. This will allow for all bus bars to be operational. I recommend to the homeowners not to put a breaker on the damaged buss in the panel. Everything is working as it should upon departure. We also scheduled an hvac technician to come out 9/9 between 2-5 to look at the furnace.
