Frequently Asked Questions

How much does it cost to fix a garbage disposal that's humming but not grinding?

The part costs about $20-50. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $170-250.

How long does this garbage disposal repair take?

This repair is rated "easy" and typically takes 5-10 minutes. The most time-consuming part is usually accessing the component, not the actual swap.

What if this isn't the problem?

Our diagnosis is 90% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "disposal makes a humming sound but the flywheel doesn't spin" would be related to the wiring harness or control board. In that case, consider calling a professional.

Should I just replace my garbage disposal instead?

A new garbage disposal costs $100-300. If yours is well under 8-15 years old, a $20-50 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
