InSinkErator Not Working After Reset: Silent vs Humming

An InSinkErator not working after reset is telling you what failed by its sound: no sound means dead power or a still-open overload, a hum means a stuck plate, and running then tripping means overload or a circuit fault. Each one gets a different test.

Which of 3 sounds does your InSinkErator make after the reset?

Your InSinkErator will do exactly one of three things when the switch goes back on: nothing, a hum with no spin, or a short run followed by a shutdown. Run cold water, flip the switch, listen for a few seconds, and flip it off. That decides your row.

This split saves a wasted wrench job and a wasted purchase. A free plate cannot explain a silent unit, and a new $149 Badger 5 will not fix a dead GFCI. A hum rules out the breaker in one second, because a motor on a dead circuit makes no sound.

Does your InSinkErator have a red reset button, or does it reset itself?

A Badger has a red button you press; a current Evolution has none, so looking for one on a current Evolution gets you nowhere. The maker’s spec sheets list Manual Reset Overload on the Badger 5 and Automatic Reset on the Evolution 1.0HP. Horsepower and warranty years below come from InSinkErator’s comparison chart.

Three wait times circulate because InSinkErator prints three. The Badger Series manual says cool 3 to 5 minutes, then lightly push the button with the power switch off. The reset support page says a tripped button sits about 1/4 in (5 mm) low, and to wait 10 minutes if it will not stay up. The EZ Connect manual gives up to 20 minutes. Reading the first two as a first and second attempt is our reconciliation, not the maker’s wording.

An older Evolution without EZ Connect falls under that page’s “All Other Disposers” group, so trust the bottom plate over the name: a red square means manual. Our garbage disposal reset button guide shows the button and the press itself in more detail. On an automatic unit, keep the switch off for the whole wait, since a cooled overload closes by itself.

All of these remain InSinkErator products under Whirlpool. Emerson agreed to sell the business for $3.0 billion in August 2022, and Whirlpool announced completion on Nov. 1, 2022, keeping it a separate business in Mount Pleasant, Wisconsin. Warranty claims still go to InSinkErator at 1-800-558-5700.

No sound after reset: test the switch, GFCI, breaker, then the outlet

A silent InSinkErator needs its power path checked from the sink outward, and all 4 steps can be done without opening the unit or touching a wire. Finish the cool-down first, because an open overload is silent too.

1. Wall switch. Confirm which switch runs the disposal. The Badger manual calls for one with a marked Off position, within sight of the sink opening, rated 1 hp minimum. Step 4 tests it.
2. GFCI. Check the under-sink outlet, then any kitchen outlet with TEST and RESET buttons, since one GFCI can protect outlets downstream. Press RESET once. If it will not hold, stop and look for water.
3. Breaker or fuse. InSinkErator’s next instruction after a reset is the service panel. Move the handle fully off, then on, once.
4. Outlet, plug-in units only. With the switch off, unplug the disposal and plug in a table lamp. Flip the switch. A lit lamp clears the switch, GFCI and breaker and puts the fault in the disposal. A dark lamp means the circuit needs work.

A hard-wired unit skips step 4, because testing it means opening a junction with 120 V behind it. Ask a licensed electrician to “verify 120 V at the disposal connection with the switch on.” Before any wrench work, a plug-in unit gets unplugged and a hard-wired unit gets its breaker turned off.

Air switch on the sink or counter

A push-button SinkTop Switch has no wire to the button, only a 6 ft air tube to a power module under the sink, per its installation guide (78196 Rev E). Check that the module cord sits in a continuously live 120 V outlet and the tube is pushed tight onto its fittings. The module’s two outlets alternate, so one is always dead, and one push moves the power. The guide warns the disposal may start when the module is plugged in, so remove any wrench first.

Batch feed models

The Evolution Cover Control has no wall switch to test. Its spec sheet lists a T-Handle Stopper Switch, and a magnetic CoverStart switch lets it run only with the cover on. Silence with no handle seated is normal. With it seated, go to the GFCI and breaker steps.

Humming InSinkErator: free the plate from below with a 1/4 inch hex wrench

A hum with no spin means the switch goes off within seconds, then the wrench that came with the unit goes in: a silver crank about 4 in long, or a standard 1/4 in Allen wrench, in the hole dead center on the underside. InSinkErator’s jam page says to crank both ways, that some force is fine, and that the wrench is designed to bend before the disposal is damaged.

Most units should reach complete circles in both directions, while the EZ Connect manual says one full revolution. Pull the wrench before power returns: the Badger manual warns of broken bones or cuts if you hold it while the motor runs. With the power still off, look down with a flashlight at the outer edge of the shredding disk and lift objects out with tongs or pliers. Never put a hand in the unit.

Builder Series, Amana and ES units get a different method on that page: with the power off, rotate the turntable from above with a wooden spoon, then use tongs. Our garbage disposal humming guide covers what jams the plate. A plate that spins freely over an empty chamber and still hums has used up the owner steps in both manuals.

InSinkErator keeps tripping: which device tripped decides the fix

A trip is 3 different faults depending on what opened, so find the device before you press anything: the overload points at the motor, a breaker at the circuit’s load, and a GFCI at leaking current.

Overload. InSinkErator names a jam, a very long run or “another issue” as triggers, and the spec sheets rate these motors Intermittent duty. Clear the chamber, cool it fully, then run cold water with no food. A clean run means load caused it, so feed peels gradually as the Badger manual says. A trip on water alone is your stop.

Breaker. The sheets list an average load of 6.3 A for the Badger 5 and 10.2 A for the Evolution 1.0HP on 120 V. On a 15 A breaker, that is 42% and 68% of the rating by our arithmetic, leaving 8.7 A or 4.8 A for anything sharing the circuit, and the sheets do not publish starting draw. Trips only when the dishwasher runs suggest sharing. Otherwise ask an electrician to “check whether this circuit is shared and test the disposal for a short.”

GFCI. Treat this as a water question first. Leave it unplugged, dry the cabinet and trace the source with our checks for water under the kitchen sink. If the cabinet is dry and the GFCI trips only with the disposal plugged in, the disposal is the likely fault.

When replacing your InSinkErator beats repairing it

Inside the warranty term, neither: call InSinkErator, because a covered claim includes parts and labor at your home. Read the serial number on the gray tag near the bottom. The first 2 digits give the year and the next 2 the month, so 2203 means March 2022. A receipt can push the start later, since the term runs from the latest of install, purchase or manufacture.

The cutoff months are our arithmetic from the maker’s chart, and street prices can differ from MSRP. Serial numbers moved to a 10-character format in summer 2024, such as IHD2101201, so text 262-233-2231 if yours has letters. Older models may carry other terms, listed in the manual for that model.

The Badger 5 warranty has three lines that change the decision. Coverage passes to any later owner of the house where the unit was first installed. A replacement gets only the unexpired balance of the original term. And the warranty is void if you attempt a repair, so stop at the manual’s steps.

Out of term, replace when the plate spins free and it still hums, or when it trips on water alone. Neither manual gives an owner a motor or overload repair procedure. Do not replace if the lamp test failed, because a new unit on a dead circuit stays silent. InSinkErator says its Quick Lock mount lets one of its models swap for another, and our walkthrough on how to remove a garbage disposal covers taking the old one off.
