What It Means
Motor Hum — No Start
Likely Causes
- Start or run capacitor failed (most common single fix on single-phase motors)
- Motor shaft seized from sitting idle
- Voltage present but motor not developing torque
Next Checks
- Test and replace capacitor — this is the most common fix for a humming motor that won't start
- Try spinning motor shaft by hand (with power OFF) — if locked, motor is seized
- If shaft spins freely and new capacitor doesn't help, motor rewind or replacement needed
