Common failures & inspection points

Contactor contact wear, pitting, or welding from repeated switching or overcurrent causes failure to start, single-phasing, or failure to open
Coil failure or incorrect control voltage causes chattering, overheating, or a contactor that will not pick up
Loose or overheated power terminals create discoloration, burning smell, voltage drop, or thermal damage
Overload relay, protection, or sensor malfunction causes nuisance trips or failure to protect the motor correctly
Control-circuit, interlock, selector-switch, or remote-command faults prevent starting or cause inconsistent local/remote operation

Service & Maintenance

Inspect contact condition where accessible, terminal tightness, heat damage, coil condition, overload and protective settings, control voltage, interlocks, remote commands, and trip history. Isolation, testing, and protection settings must follow the vessel electrical procedure and manufacturer documentation.
