Industrial Air Compressor Breakdown Repairs & Electrical Fault Finding

Instant tripping on startup is typically caused by a failed star-delta changeover contactor, a shorted motor winding, a seized compressor air-end, or an unloader valve stuck closed that forces the motor to start against full line pressure. We conduct insulation resistance and contactor testing to determine whether the fault is electrical or mechanical resistance.

Yes, we work across all major industrial compressor electronic controllers. Whether the screen displays communication errors, emergency stop circuit lockouts, or high-discharge temperature trips, we trace the associated field sensors and safety inputs to clear the fault safely.

Our service vans carry a broad range of heavy-duty industrial contactors, thermal overload relays, auxiliary switches, and standard pressure controllers to complete most emergency repairs in a single visit. For brand-specific electronic controllers, we utilise our local Perth supplier network for rapid turnaround.

Yes, if an older compressor has an obsolete, unreliable starter box or experiences high peak demand penalties, we can design and install a new control panel with a modern soft starter or Variable Speed Drive to reduce mechanical stress and cut power costs.
