Never put your hand in
Even with the power off, reaching into the chamber is a bad habit. Use tongs, pliers, or needle-nose to pull the object. The grinding ring has sharp edges long before the motor ever turns.

About Twin City Pipeworks
Why Homeowners Trust Us for Garbage Disposal Humming
If your garbage disposal is humming but not working, the motor is fine and something has jammed the grinding plate so it cannot turn. That is usually a two-minute fix you can do yourself, and this guide walks you through it before you pay anyone. Twin City Pipeworks is an owner-run, licensed MN plumbing shop that has handled disposals across the east metro and St. Croix Valley for 20 years, and Dave will be the first to tell you: if the hex key frees the plate and it runs clean, you are done, no visit needed. But there is a short list of symptoms where the smart move is to stop the DIY and book a garbage disposal repair in the east metro instead, and knowing that line saves you from turning a jam into a flooded cabinet.
Here is the pattern we see over and over on aging disposals in Stillwater, Oakdale, Woodbury, and Lake Elmo homes. That hum is the motor drawing power against a locked flywheel, and if you keep flipping the switch hoping it clears, you are cooking the motor. The reset button trips for exactly this reason, to protect the motor from the heat. So the order matters: kill the power, clear the jam by hand, then reset. Do it in that sequence and a humming disposal is a free fix. Do it out of order and you can burn out a unit that had years left.
Garbage Disposal Humming But Not Working: What the Hum Means
A humming disposal that will not spin is almost always a jammed flywheel, not a dead motor. Something hard, a cherry pit, a bit of bone, a shard of glass, a stray twist tie, has wedged between the grinding plate and the ring and locked it. The motor still runs, which is why you hear the hum, but it physically cannot turn. The good news: freeing it is a two-step job with a tool that shipped in the box.
With the power off, here is the sequence that clears the large majority of humming disposals we get asked about:
- Find the hex port. On the bottom center of the unit is a six-sided hole. The hex key (Allen wrench) that came with the disposal fits it. A 1/4-inch Allen wrench works if you lost the original.
- Work the flywheel loose. Insert the key and turn it back and forth, firmly, until it spins a full rotation freely in both directions. You are physically breaking the jam loose. You will often feel the object let go.
- Fish out the culprit. With the power still off, shine a light in the chamber and use tongs or pliers, never your hand, to remove whatever caused the jam.
- Hit the reset. Press the small red or black reset button on the bottom of the unit. If it had tripped, it clicks in.
- Power back on and test. Restore power, run cold water, and flip the switch. A freed disposal spins right up.
If it runs clean and quiet after that, you fixed it, and you do not need us. Genuinely. Do not book a plumber for a jam that a hex key already cleared.

Garbage Disposal Jammed: How to Fix It Without Wrecking the Unit
A jammed garbage disposal is a fixable-at-home problem right up until it is not. These are the do's and don'ts we give neighbors so a simple jam does not turn into a replacement:
Use the hex key, not a broom handle
The old trick of jamming a wooden spoon or broom handle down the top to lever the plate can crack the flywheel or snap the mount. The hex port on the bottom is there for exactly this. Use it.
Stop flipping the switch
Every time you hit the switch on a locked unit, the motor draws hard against the jam and heats up. Two or three tries and you can burn the windings. If it hums, kill the power and clear the jam by hand instead.
Run cold water, not hot
Once it is spinning again, flush with cold water. Cold keeps any grease solid so it grinds and washes out instead of coating the chamber. Hot water melts grease that re-hardens downstream in the trap.
Stop Here and Book: The Symptoms That Are Not a DIY Fix
This is the part most how-to articles skip, and it is the part that actually protects your kitchen. Some disposal symptoms mean the jam trick will not help and pushing further makes it worse. If you see any of the following, stop and book a repair rather than fighting it.
- It still hums after the flywheel spins free. If the hex key turns a full clean circle and it still just hums when powered, the motor or the switch has failed. A freely spinning plate plus a hum equals an electrical or motor problem, not a jam.
- It trips the breaker or keeps tripping the reset. A unit that pops the breaker, or trips its own reset again within a minute or two of clearing, is drawing too much current. The motor is overloading, and that is a diagnose-and-repair call.
- It leaks from the side or bottom of the unit. A drip under the body, not the sink flange, means the internal seals are gone. Disposals are sealed units. Once the body leaks, it is a replacement, full stop.
- There is a burning or electrical smell. That is insulation cooking on an overloaded or failing motor. Cut the power and leave it off.
The homes we service in Woodbury and Maplewood are hitting the age where a lot of disposals installed in the 2010s are simply worn out. When a 10-plus-year-old unit starts jamming every few weeks, the grinding components are done. We would rather swap it once than un-jam it four times.
Most disposals last 8 to 12 years. Past that, a unit that keeps jamming, hums with a free plate, or leaks from the body is telling you it has reached the end. When it is time, book a garbage disposal repair in the east metro online and Dave will diagnose the real issue, unjam or reset it if that is genuinely the fix, or replace it with a straight answer on what fits your sink.

What Happens on a Garbage Disposal Repair Visit
When the DIY line has been crossed, here is exactly how a scheduled disposal visit goes, so you know what you are booking. No mystery, upfront per-task pricing before any work begins:
Diagnose before touching
We run the unit, check the reset, look at the mounting assembly, and inspect the drain connection to the trap. The point is to find the real cause before any part gets pulled, so you are not paying for a guess.
Unjam or reset on the spot
If it turns out to be a jam or a tripped reset that you could not reach, that gets handled right there. If that is all it needed, that is all you pay for. We tell you honestly.
Replace when it is worn out
If the motor is dead, the body is leaking, or the grinding components are gone, we replace it. Cord-connected or hardwired, we match a unit to your sink and usage rather than whatever is on the truck.
Check the connections
We confirm the drain and mounting are sealed and the dishwasher knockout is handled correctly. If your shutoffs or supply lines under the sink are shot, we can sort that on the same visit.
While We Are Under the Sink: The Smart Add-On
A disposal repair opens up the whole under-sink cabinet, and that is the cheapest time to fix the other things that tend to fail down there. The cabinet is already cleared, the trap is accessible, and a second visit later costs you a second visit.
While we are in there, we can knock out the under-sink shutoff and supply-line work while we are in the cabinet: swapping corroded shutoff valves, replacing a brittle 20-year-old supply line, or fixing a faucet that has been dripping. One visit, one trip charge, everything under that sink handled. It is the kind of thing that only makes sense to bundle, so we always mention it.

Frequently Asked Questions
Why is my garbage disposal humming but not spinning? +
A hum with no spin almost always means the flywheel is jammed. Something hard, a pit, a bone chip, a bit of glass, or a stray utensil, has locked between the grinding plate and the ring, so the motor runs but cannot turn. Cut the power, then use the hex key in the port on the bottom center of the unit to turn the flywheel back and forth until it spins free, remove whatever caused the jam with tongs, and press the reset button. If it still just hums after the plate spins freely, the motor or switch has failed and it needs a repair.
My garbage disposal reset button will not stay in or keeps tripping. What now? +
If the reset button pops back out within a minute or two of pressing it, the motor is overloading, and repeatedly resetting will not fix it. Sometimes the flywheel is still jammed, so free it with the hex key first and try the reset again. But if the reset keeps tripping on a free-spinning unit, or the disposal trips your breaker, the motor is drawing too much current and that is a diagnose-and-repair call. Do not keep cycling the reset, because you can burn the motor. Book a garbage disposal repair and we will find out whether it is the motor, the wiring, or something still caught in the chamber.
When should I replace a garbage disposal instead of repairing it? +
Disposals are not really a rebuildable appliance, so the decision is usually unjam, reset, or replace. Replace it when the body leaks from the side or bottom (the internal seals are gone), when the motor is dead or hums with a freely spinning plate, when there is a burning smell, or when a unit older than about 10 years starts jamming every few weeks. Most disposals last 8 to 12 years, so past that a chronic problem is the unit telling you it is worn out. A simple jam or a tripped reset on a newer unit is a fix, not a replacement. We give you a straight answer on which situation you are in with upfront per-task pricing.
Is it safe to fix a jammed garbage disposal myself? +
For a straightforward jam, yes, as long as you kill the power first. Flip the switch off and unplug the unit or shut its breaker, then use the hex key on the bottom to free the flywheel and tongs to remove the object. Never put your hand in the chamber and never use a broom handle down the top to lever it, which can crack the flywheel or mount. If clearing the jam does not fix it, or you see leaking, a burning smell, or a reset that keeps tripping, stop and book a plumber. Getting the mounting torque wrong on a reinstall can crack your sink flange, so a leaking or failed unit is worth handing off.
Do you offer emergency service if my disposal quits? +
No, and a stuck disposal almost never needs it. Twin City Pipeworks is an owner-run shop serving the east metro and St. Croix Valley by appointment, Monday through Friday. A jammed or dead disposal is not an emergency: you can stop using that side of the sink, run the dishwasher on the drain if it shares one, and book a proper repair on the next available slot. Book online any time, or call or text (651) 247-4495.
