Garbage disposal runs but occasionally stalls or slows dramatically when small amounts of food are added.

Safety first: Turn off power at the breaker before accessing any electrical components.

• Test with water only: Run the disposal with just water. If it still slows or labors, the issue is likely electrical or mechanical, not load-related.
• Check voltage: Have a qualified person verify that the supply voltage at the disposal is within the specified range while running.
• Inspect capacitor: Locate the Maxmatic start capacitor and check for bulging or leakage. Replace with an identical rating if defective.
• Listen for bearing noise: Grinding or rumbling sounds indicate internal friction that can cause stalling.

If performance does not improve after capacitor replacement and proper voltage is confirmed, the motor is likely failing and the disposal should be replaced.
