Possible Causes
Prolonged overload on Calpeda motor, Blocked motor ventilation, Failed start capacitor causing locked-rotor heating, Internal winding short in Calpeda motor
How to Fix / Troubleshooting
Safety first: Immediately switch off power at the breaker. Do not touch the motor until it has cooled and do not attempt to restart.
- Inspect for visible damage: After cooling, look for burnt wiring, melted insulation, or discoloration on the motor and terminal box.
- Check ventilation and load: Ensure the motor cooling fan and vents are clear, and verify that the pump is not overloaded by a blocked system or incorrect impeller.
- Test windings: Use a multimeter and megohmmeter to check winding resistance and insulation. Abnormal readings indicate internal damage.
- Replace motor if burnt: If there is a strong burnt smell or visible winding damage, replace the Calpeda motor. Continued use is unsafe.
