How to Fix / Troubleshooting
Safety first: Leave the breaker OFF until the fault is identified. Do not repeatedly reset a tripping breaker.
- Inspect motor exterior:
- Look for burn marks, melted plastic, or strong burnt smell from the Jandy motor.
- Check for water intrusion:
- Inspect the motor end bell and conduit entry for signs of water.
- Verify wiring:
- Confirm connections match the Jandy wiring diagram and voltage rating.
- Test shaft rotation:
- If the shaft is locked, the motor is likely failed and must be replaced.
- Professional testing:
- Have an electrician or technician perform insulation resistance and winding tests.
