Possible Causes
Locked rotor (seized bearings or impeller), Shorted windings, Incorrect voltage connection, Prolonged operation under overload
How to Fix / Troubleshooting
Safety: Immediately turn off power at the breaker. Do not attempt to restart the pump until inspected.
- Check shaft rotation: With power off, attempt to rotate the motor shaft. If it is seized, inspect for debris in the impeller or failed bearings.
- Inspect wiring: Open the motor wiring compartment and look for burned connections or signs of overheating. Correct any miswiring according to the Sta-Rite wiring diagram.
- Assess motor condition: A strong burnt odor or visible smoke usually indicates irreversible winding damage. Replace the motor assembly.
- Investigate root cause: Check for system issues (blocked lines, closed valves) that may have overloaded the pump to prevent recurrence.
