Every garburator—or garbage disposal—is equipped with a small but critical safety feature designed to save the motor from self-destruction. This feature, known as the thermal overload protector, manifests as a simple reset button. When a garburator stops mid-grind or refuses to turn on while making a faint humming sound, the reset button is usually the first place to look. This internal circuit breaker trips to cut power when the motor experiences excessive resistance or heat, preventing a kitchen convenience from becoming a fire hazard.

Understanding the Garburator Reset Button

The reset button serves as the unit's frontline defense. Mechanically, the motor inside the disposal relies on a spinning flywheel to grind food waste. If a hard object like a peach pit or a stray silver spoon wedges between the impeller and the grind ring, the motor stalls. Because electricity continues to flow into a stalled motor, it generates heat rapidly. Without a trip mechanism, this heat would melt the motor windings. The reset button detects this thermal spike or current surge and pops out, effectively "killing" the power locally before the house's main circuit breaker ever feels the strain.

Usually, when this button trips, it will protrude about a quarter to a half-inch from its housing. You might feel a distinct "click" when you press it back in, signaling that the internal connection has been restored.

Where to Find the Reset Button on Major Brands

Locating the button can be frustrating while crouching in a dark cabinet filled with cleaning supplies. While most manufacturers place it on the bottom of the unit, the exact coordinates vary by brand and model series.

InSinkErator (Badger and Evolution Series)

InSinkErator is the most common brand in North American households. On models like the Badger 5 or the Evolution Excel, the reset button is located on the very bottom of the unit, dead center. It is almost always a small, bright red square or circle. If you run your hand along the underside of the cylinder, you will feel it near the center point where the motor housing ends.

Waste King

Waste King disposals often have a slightly different configuration. On many of their popular models, such as the L-1001 or the Legend series, the reset button is located on the lower side of the unit’s exterior shell, usually opposite the side where the power cord enters. It is typically a small red button recessed slightly within a plastic guard to prevent accidental presses.

Moen

Moen disposals, particularly the GX and GXP series, follow a similar logic to InSinkErator but often place the button on the lower front or side for easier access. The button is red and sits flush when the machine is healthy, popping out noticeably when a jam occurs.

General Electric (GE) and Whirlpool

These units almost universally place the reset button on the bottom plate. However, unlike the bright red InSinkErator buttons, GE sometimes uses a black button that can be harder to spot in low light. If you cannot see a red button, look for a small protruding nub on the bottom casing.

Why Your Garburator Reset Button Trips

If you find yourself resetting the unit frequently, it is rarely a fault of the button itself. Instead, the button is reacting to one of four common mechanical or electrical stressors.

1. Mechanical Jams

This is the culprit in 90% of cases. Fibrous foods (celery, corn husks), hard objects (bones, fruit pits), or non-food items (twist ties, bottle caps) can wedge the spinning plate against the stationary grind ring. The motor tries to overcome the resistance, draws more current, and triggers the thermal protector.

2. Overheating from Extended Use

Garburators are designed for intermittent use—usually no more than 60 to 90 seconds at a time. If you are cleaning up after a large dinner party and run the disposal continuously for five or ten minutes, the motor will naturally heat up. The thermal sensor will trip to allow the motor to cool down, even if there is no jam.

3. Aging Motor Windings

As a garburator nears the end of its lifespan (typically 8 to 12 years), the internal insulation on the motor windings begins to degrade. This causes the motor to run hotter than it did when new, leading to frequent "nuisance tripping" where the button pops even during light use.

4. Electrical Surges

Occasionally, a surge in the home’s electrical system or a loose wire in the disposal's junction box can cause a momentary spike that trips the sensitive overload protector.

How to Safely Reset Your Garburator

Resetting the unit is a straightforward process, but safety is paramount. Follow these steps to ensure you don't damage the machine or yourself.

Step 1: Power Down Turn the wall switch to the "Off" position. For added safety, unplug the unit from the outlet under the sink. If the unit is hard-wired, you may choose to flip the circuit breaker at the main panel, though the wall switch is generally sufficient for a simple reset.

Step 2: Inspect the Grinding Chamber Using a powerful flashlight, look down the drain. If you see a visible obstruction—like a bone or a piece of plastic—use long-nosed pliers or kitchen tongs to remove it. Never put your hand inside the garburator. Even with the power off, the blades can be sharp, and there is a risk of mechanical tension releasing suddenly.

Step 3: Allow for Cooling If the motor feels hot to the touch or if the unit just stopped while running, wait at least 5 to 10 minutes. The thermal protector is a bimetallic strip that needs to physically cool down before it can latch back into the "on" position. If you press it too soon, it will simply pop back out.

Step 4: Press the Button Reach under the unit and press the red button firmly. You should feel a click. If the button feels mushy or stays out, wait another few minutes for it to cool further.

Step 5: Test the Unit Restore power by plugging it back in. Turn on a steady stream of cold water. Flip the wall switch briefly (for about one second) to see if the motor turns. If it hums but doesn't spin, turn it off immediately; a jam is still present.

The "Humming" Dilemma: Using the Hex Key

If you have pressed the reset button but the unit only makes a low humming sound when turned on, the motor is still jammed. Repeatedly pressing the reset button and letting it hum will eventually burn out the motor. This is where the manual unjamming procedure comes in.

Most InSinkErator and similar models have a hexagonal hole in the center of the bottom plate. This hole connects directly to the motor's driveshaft.

  1. Locate the silver, L-shaped Allen wrench (hex key) that came with your unit. If you lost it, a standard 1/4-inch hex key from a hardware store will work.
  2. Insert the key into the hole at the bottom of the disposal.
  3. Rotate the key back and forth. You will likely feel significant resistance at first. Force the key through the resistance until you can spin the motor 360 degrees freely.
  4. Once the motor spins freely via the wrench, remove the wrench and try the reset button again.

What to Do When the Reset Button Won't Stay In

A reset button that refuses to stay depressed is a symptom of one of two things. Most commonly, the unit hasn't cooled down enough. The internal metal components remain expanded from heat, preventing the latch from catching. Wait 30 minutes and try again.

However, if the button pops out immediately every time you flip the wall switch—even after an hour of cooling—there is likely a direct electrical short inside the motor. In this scenario, the unit has reached the end of its functional life. Internal seals may have failed, allowing water to enter the motor housing, which creates a permanent short circuit. For safety reasons, these units are not user-serviceable and should be replaced.

Why Your Garburator Might Not Have a Reset Button

While almost all modern units manufactured in the last 20 years include this feature, you might encounter an older model or a specific budget brand that lacks an external button. In these cases, the manufacturer relies on the home's GFCI (Ground Fault Circuit Interrupter) outlet or the main circuit breaker panel.

If your unit stops and you cannot find a button on the bottom or sides:

  1. Check the outlet it is plugged into. If it is a GFCI outlet (the kind with "Test" and "Reset" buttons between the two plugs), look to see if the little light is on. Press the "Reset" button on the outlet itself.
  2. Check your home’s electrical panel. Look for a breaker labeled "Disposal" or "Kitchen" that has moved to the middle or "Off" position. Flip it fully to "Off" and then back to "On."

Prevention: How to Stop the Button from Tripping

The best way to manage the garburator reset button is to ensure you never have to use it. Proper operation and maintenance can extend the life of your motor and keep the internal breaker from ever needing to trip.

The Cold Water Rule

Always run cold water before, during, and for 15 seconds after using the disposal. Cold water keeps the motor cool and ensures that any fats or greases remain solid. If you use hot water, fats liquefy and then solidify further down the pipes, causing clogs that create back-pressure on the disposal motor.

Mind the Volume

Do not feed the disposal a large plate of scraps all at once. Feed items slowly, one handful at a time. Overloading the chamber forces the motor to work at its maximum torque, which generates heat and leads to tripping.

Know the "No-Go" List

Avoid putting the following items down the drain, as they are the leading causes of jams:

  • Fibrous Vegetables: Celery, onion skins, and corn husks can wrap around the blades like string, stalling the motor.
  • Starchy Pastes: Large amounts of pasta, rice, or potato peels can create a thick slurry that jams the impeller.
  • Hard Objects: Olive pits, unpopped popcorn kernels, and bones can wedge between the spinning and stationary parts.
  • Coffee Grounds: While they don't usually jam the motor, they accumulate in the trap and create clogs that can cause the unit to overheat.

Monthly Maintenance

Once a month, grind a tray of ice cubes and a handful of rock salt. The ice chips away at the biofilm on the blades, while the salt provides a mild abrasive to clean the grind ring. This keeps the mechanical parts moving with minimal friction, reducing the electrical load on the motor.

When to Replace vs. When to Reset

A single trip of the reset button every few months is normal and usually indicates a minor user error, such as trying to grind a particularly tough piece of waste. However, you should consider a replacement if you experience the following:

  • Frequent Tripping: If the button pops every few days despite careful use, the motor is likely failing.
  • Leaking: If you see water dripping from the bottom of the unit near the reset button, the internal seals are gone. This is a significant electrical hazard.
  • Persistent Noise: If the unit hums even after you've manually cleared a jam with a hex key, the motor bearings may have seized.

In most cases, the reset button is a homeowner's best friend. It is a simple, zero-cost fix for a common kitchen problem. Before you call a plumber or head to the hardware store for a new unit, always reach under the sink and look for that little red lifesaver. Usually, a firm press and a five-minute wait are all it takes to get your kitchen back in working order.
