A garbage disposal that's been making grinding sounds for months before stopping entirely often has a seized bearing or cracked impeller โ signs the motor isn't worth repairing. Our techs in Vanduser tell you honestly whether a repair or a same-day unit swap makes more financial sense.

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.
Most disposal calls complete in 30โ60 minutes โ same visit, flat-rate pricing.
A disposal that hums with no rotation has a jammed impeller plate โ the spinning plate has been stopped by a bone fragment, a piece of silverware that fell in, or hard food buildup around the shredder ring. We use the jam-clearing wrench at the center motor socket to manually rotate the impeller free, remove any obstruction from the grinding chamber, and press the thermal overload reset button before testing.
A disposal that makes no sound when switched on has either tripped its thermal overload protector (the red button on the bottom โ press it and try again) or has a wiring issue at the switch or disposal unit. We check the reset button, test for power at the disposal's wire connection, and test the wall switch for continuity.
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).
If the turntable bearing has failed โ indicated by a loud rumbling throughout operation rather than specific impact sounds โ that's an internal motor wear failure that warrants replacement.
A disposal that grinds normally but drains slowly has a blockage in the drain arm or p-trap โ not an internal disposal problem. Food particles and grease accumulate in the short drain arm between the disposal outlet and the p-trap. We disconnect and clean the drain arm, clear any p-trap buildup, and reinstall with clean connections.
Replacement includes: safely disconnecting electrical at the junction box under the sink, removing the old unit and mounting assembly, installing the new unit with correct wiring and plumbing connections, testing for full jam-free operation, and verifying zero leaks at all connections before leaving.
A disposal call takes 30โ60 minutes in most cases. Here's exactly how it goes โ from your first call to a clean, functional kitchen drain.
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 decide. We don't upsell replacement when repair is the right answer, and we don't push a cheap repair that won't hold on a unit that's genuinely at end of life.
After repair or replacement, we run the disposal through a full test: several cycles with water running, check under the sink for any drip at all connection points, and confirm the drain arm clears at a normal rate.

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.
Disposal making a loud rattling noise but still grinding. Tech took out a bottle cap that had gotten past the splash guard and was spinning around the grinding chamber. Cleaned out the chamber, confirmed the impeller wasn't damaged, tested for smooth operation. Twenty-minute visit, everything working perfectly.
Disposal leaking from the sink collar area. Previous owner had installed it with silicone instead of plumber's putty at the flange โ silicone doesn't hold the mounting pressure correctly and had separated. Tech re-seated the flange with putty, re-tightened the mounting ring, and the leak stopped. Tested with a full minute of running water. All clear.

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

Our disposal techs in Vanduser, MO carry the tools and replacement units to resolve any disposal problem same visit. Flat-rate pricing, honest repair-vs-replace guidance, and no unnecessary upselling.
