We run electrical tests (RCD trips, earth continuity, insulation resistance), check firmware/LED fault codes and diagnose faults on Mode 3/Type 2 units.
Minor repairs, report & liaison
We complete minor repairs on site, issue a service report with recommendations and, where needed, contact the manufacturer or installer to support warranty claims.
