Maytag Dishwasher MDB4630AWS4 Won't start or doesn't start

This run capacitor helps start and keep the motor running smoothly by providing the necessary phase shift and torque boost. A weak capacitor can cause hard starting, humming, or intermittent motor operation.

• Supplies continuous phase shift to maintain motor rotation
• Helps the motor start reliably under load
• Symptoms can include humming, slow or no start, or overheating shutdown
• Restores normal operation when the original capacitor has weakened

• Disconnect power before servicing; discharge the old capacitor safely
• Note wire locations and transfer leads to the new capacitor one-by-one
• Mount securely in the original bracket or location to prevent vibration
• If the motor still won't start, further diagnosis of the motor or start device may be required
