GSHA Services, LTD brought an aging Generac home standby generator back to reliable service for a homeowner in Belvidere, IL. After a diagnostic visit identified fault codes and a fuel supply issue, our generator technician performed a full air-cooled tune-up with new oil, oil filter, air filter, and spark plugs, corrected the natural gas line and pressure at the unit, cleaned the enclosure, and later replaced the failed controller circuit board so the generator exercises on schedule and transfers automatically during outages. Every repair was load-tested before we left. Need generator repair, a controller replacement, or an annual generator tune-up in Belvidere, Rockford, Poplar Grove, or Boone County? GSHA Services is an authorized Generac service dealer with parts on the truck and same-week appointments.
