It always seems to happen at the worst moment — you flip the switch under the sink and nothing happens. No hum, no grind, just silence. If your garbage disposal won’t turn on in your Leesburg home, don’t panic. Before you assume the unit is dead and needs replacing, there are a few simple things you can check yourself. And if those steps don’t solve the problem, Platinum Appliance Repair is here to help with same-day service throughout Loudoun County and the surrounding Northern Virginia area.
Start Here: Check the Reset Button
This is the most commonly overlooked fix — and the easiest. Nearly every garbage disposal has a small reset button located on the bottom of the unit, underneath your sink. When a disposal overloads (from too much food waste or a jam), a built-in thermal overload protector trips and cuts power to the motor automatically.
Here’s what to do:
- Look under the sink and locate the disposal unit itself.
- Find the small red or black button on the underside of the unit.
- Press it firmly until you feel it click into place.
- Wait 10 minutes, then try the wall switch again.
If the reset button keeps popping back out, that’s a sign of a persistent jam or a failing motor — time to call a technician.
Is the Disposal Getting Power?
If resetting doesn’t work, the next step is confirming the unit is actually receiving electricity. Check these two things:
- The outlet under the sink: Most disposals are plugged into an outlet inside the cabinet. Make sure the plug hasn’t come loose.
- Your circuit breaker panel: Head to your breaker box and look for a tripped breaker. It will be in a middle position between ON and OFF. Flip it fully off, then back on.
Homeowners in Ashburn, Sterling, and other parts of Loudoun County often find that a tripped breaker is the culprit — especially in older homes where the kitchen circuit is shared with other appliances.
Listen for a Humming Sound
If you flip the switch and hear a humming noise but the disposal still doesn’t spin, that tells you the motor is receiving power but the grinding plate is jammed. This is a mechanical issue, not an electrical one.
To clear a jam safely:
- Turn the disposal switch off and unplug the unit from the outlet under the sink.
- Never put your hand inside the disposal.
- Use the hex wrench (Allen key) that came with the unit — or a standard ¼-inch Allen wrench — and insert it into the hole at the very bottom center of the disposal.
- Work the wrench back and forth to manually free the grinding plate.
- Plug the unit back in, press the reset button, and test it again.
If you can’t locate the jam or the plate won’t move, it’s best to stop there and contact a professional. Forcing a seized motor can cause permanent damage.
Check the Wall Switch
It sounds obvious, but faulty wall switches are a surprisingly common cause of disposal problems. If everything else checks out, the switch itself may have failed. You can test this with a basic multimeter or simply have an appliance technician assess the wiring. This is especially relevant in homes in Leesburg, Herndon, and Warrenton where older kitchen wiring may be due for an update.
When the Disposal Is Truly Dead
If you’ve worked through every step above and the disposal still won’t respond, the motor has likely burned out or an internal component has failed. At that point, repair or replacement is the right move — and a certified technician can help you decide which option makes the most financial sense based on the age and brand of your unit.
