Your disposal hums but won't spin โ the impeller plate is jammed. It's completely silent when you flip the switch โ the thermal overload protector has tripped or the motor has failed. Water drips from the sink collar โ the sink mounting gasket has deteriorated. Each of these is a different diagnosis, and each has a different solution. Masters Plumbing Service's techs in Erwin, NC arrive with the jamming tools, reset wrench, and replacement units to resolve any disposal failure same visit.

Garbage disposal failures have specific, diagnosable causes. Our techs don't just swap units โ they identify what failed and whether repair or replacement is the right call for your situation.
A disposal that hums but won't spin almost always just needs the jam cleared with an Allen wrench at the center socket and the reset button pressed โ a 5-minute fix that doesn't require a new unit.
InSinkErator (Badger, Badger 5, Compact, Evolution series), Moen GXS/GX series, Waste King, KitchenAid, and Whirlpool disposals all mount differently and have specific jam-clearing procedures. We know the mounting assembly for each brand and carry the correct jam-clearing wrench sizes.
We give you the actual cost comparison. If clearing the jam and pressing the reset button fixes it, that's what we do. If the motor has failed, we show you the replacement options and install same-day.
A disposal isn't an isolated appliance โ it connects to the sink drain, the dishwasher drain (if present), and the drain arm leading to the p-trap. We inspect the full connection set during any disposal call: drain arm slope, dishwasher drain knockout (if a dishwasher is being added), and p-trap connection integrity.
From a simple jam clear to a full replacement with drain reconnection, here's how we handle each garbage disposal scenario in Erwin, NC.
If the jam-clearing wrench won't budge the impeller, the motor shaft may be seized rather than just stuck from debris โ we distinguish between the two before recommending replacement.
If power is confirmed at the disposal and it still won't start after a reset, the motor is failed. We then move to the replacement conversation with honest cost comparison.
Disposal leaks come from three locations: the sink flange (top of the unit where it mounts to the sink drain opening โ repaired by re-sealing the flange with plumber's putty and re-tightening the mounting ring), the side port (dishwasher drain hose connection โ usually a loose hose clamp or cracked fitting), or the bottom of the unit (internal body crack or failed internal seal โ indicates replacement needed).
An unusually loud grinding, rattling, or metal-on-metal sound from a disposal almost always means either a hard object (bottle cap, small utensil, pit from stone fruit) is in the grinding chamber, or an impeller piece has broken and is contacting the shredder ring. We access the grinding chamber safely, remove any foreign objects, and inspect the impeller and shredder ring for damage.
If the slow drain persists after cleaning the drain arm and p-trap, a camera scope of the kitchen drain line is the next step to check for blockage further downstream.
When the motor has failed, the unit body is cracked, or the existing unit is underpowered for the household's use pattern, we replace the disposal with a new unit matched to the sink drain configuration. We carry 1/2 HP, 3/4 HP, and 1 HP units from InSinkErator and other major brands on our trucks for same-day installation.
No guesswork โ we diagnose before we quote, and quote before we start.
Hums but won't spin, completely silent, grinding noise, leaking, or slow to drain โ each symptom tells our dispatcher which tools and possible replacement units to have on the truck. Knowing the disposal brand is a plus but not required.
The tech identifies the failure type in minutes: jam test at the motor socket, reset button check, power confirmation at the wire connections, leak source tracing. We know what each symptom means and we go straight to confirming it.
You receive a flat-rate price for the repair option and, if relevant, the replacement option with unit cost included. For a simple jam clear, that's a single, low line item. For a failed motor, we show you the new unit cost and installation price together.
We leave the cabinet dry and the disposal running quietly. If a dishwasher drain hose was involved, we run a dishwasher cycle to verify no backup occurs.

Disposal hummed and wouldn't spin. I'd already tried the Allen wrench trick without success. Masters Plumbing Service's tech came out, worked the impeller free from underneath while removing a piece of broken ceramic that had fallen in โ it had wedged between the impeller and the grinding ring in a way I couldn't have cleared from the top. Cleared the jam, pressed the reset, tested. Five-minute fix. Honest about the call minimum charge, no attempt to upsell a replacement on a perfectly good motor.
After we added a dishwasher, it started backing up every cycle. Masters Plumbing Service found the problem immediately โ the previous installer had forgotten to knock out the dishwasher drain plug inside the disposal inlet. The plug was blocking the drain port. Two-minute fix. The tech also tightened the dishwasher drain hose clamp, which was loose. Never had another backup.
Old disposal stopped working completely โ no hum, nothing. I assumed the motor failed. The tech checked the wiring first โ found a loose wire nut at the junction box under the sink that had vibrated loose over the years. Reconnected the wire, reset the overload button, disposal came right on. Would have been embarrassing if I'd bought a replacement unit. Masters Plumbing Service's thoroughness saved me a few hundred dollars.

Our trucks carry replacement disposal units in common horsepower ratings for same-day installation when the motor has failed.
