Motor Failure Diagnosis
Visual Motor Inspection
Check for burn marks, melted components, or physical damage
⚠️ Warning: Burnt smell indicates internal damage
Electrical Testing
Test voltage at motor terminals and continuity
⚠️ Warning: No continuity means winding failure
Shaft Rotation Test
Try turning motor shaft by hand when power is off
⚠️ Warning: Seized shaft indicates bearing failure
Capacitor Testing
Test start and run capacitors with multimeter
⚠️ Warning: Bad capacitor can mimic motor failure
Age Assessment
Consider motor age and repair history
⚠️ Warning: Motors over 10 years often not worth repairing
Types of Motor Failure
Electrical Failures
