Common Causes of Garbage Disposal Humming

Obstructed Blades: One of the most common reasons for a garbage disposal humming is obstructed blades. This can occur when items like cutlery or other foreign objects are accidentally dropped into the disposal, causing the blades to get stuck.
- How to Repair:
  - Never insert your hand into the disposal. Always cut the power to the unit and use tongs or needle-nose pliers to remove the obstruction.
Clogged Disposal: Another reason your garbage disposal may be humming is due to a clog. This can happen when non-food items or substances like coffee grounds, hot grease, or clam shells are introduced into the disposal, preventing the blades from moving.
- How to Repair:
  - Check for clogs and remove any blockages to allow the blades to move freely.
Disposal Needs to Be Reset: Garbage disposals often come equipped with a reset switch, usually located on the bottom of the unit. If the disposal continues to hum even after checking for obstructions, a reset may be necessary.
- How to Repair:
  - Locate the reset switch on your disposal unit and press it to reset the appliance.
Tripped Breaker or GFCI Switch: If the disposal motor is humming but the blades aren’t turning, it could be due to a tripped circuit breaker or GFCI outlet. This is typically caused by electrical issues or overheating.
- How to Repair:
  - Check the circuit breaker and GFCI outlet for any tripped switches and reset them if necessary.
Overheating Unit: An overheating motor can also lead to a garbage disposal humming sound. This can happen if the motor is faulty, the blades are dull, or if improper items are being disposed of.
- How to Repair:
  - Allow the disposal to cool down before attempting to use it again. Avoid putting excessive strain on the appliance to prevent overheating.
Faulty Motor: If your garbage disposal is nearing the end of its lifespan, a humming noise could be a sign of a faulty motor. This may require replacement of the disposal unit.
- How to Repair:
  - If the motor is deemed to be the issue, consider replacing the garbage disposal for optimal performance.
