Completely silent with no hum
You flip the switch and get nothing at all—no sound, no vibration, no brief hum.
Start here: Start with the disposal reset button and the GFCI or outlet feeding the unit.
Dead disposal troubleshooting
Moen Garbage Disposal No Power
Direct answer: If your Moen garbage disposal has no power and makes no sound at all, the most common causes are a tripped reset button on the disposal, a tripped GFCI outlet, a switched outlet that lost power, or a failed wall switch. If power is reaching the disposal and it still stays completely dead, the disposal itself is usually the problem.
Most likely: Start with the reset button on the bottom of the disposal and the nearby GFCI outlet. Those two checks solve a lot of "completely dead" calls.
First separate dead-silent from humming. If it hums, that is usually a jam, not a no-power problem. Reality check: a disposal that suddenly went silent after a hard load often just tripped its own reset. Common wrong move: holding the wall switch on while repeatedly jabbing the reset button.
Don’t start with: Don’t start by buying a new disposal or taking the unit apart. A dead disposal is often just a lost power issue upstream.
If it is totally silentCheck the reset button, GFCI, and outlet power before blaming the disposal.
If it hums but will not spinTreat it like a jammed disposal, not a no-power problem.

What “no power” usually looks like on a garbage disposal
Worked before, then suddenly went dead
It stopped after a heavy load, a utensil drop, or a stall and now will not respond.
Start here: Let it cool for a minute, clear any jam safely, then press the disposal reset button once.
Switch feels normal but disposal stays dead
The wall switch clicks like usual, but the disposal does not react.
Start here: Check whether the switched outlet has power and whether the wall switch has failed.
Outlet under the sink seems dead too
The disposal and anything else plugged into that outlet do not work.
Start here: Look for a tripped GFCI outlet or breaker before focusing on the disposal itself.
Most likely causes
1. Tripped garbage disposal reset button
A disposal that overheated or stalled will often trip its small reset on the bottom and go completely dead until it cools and resets.
Quick check: Press the reset button once with the wall switch off. If it clicks and the disposal runs again, the motor overload had tripped.
2. Tripped GFCI outlet or lost outlet power
Many disposals are plugged into a GFCI-protected outlet or share protection with a nearby kitchen outlet. When that trips, the disposal looks dead.
Quick check: Press TEST and RESET on nearby GFCI outlets and plug in a lamp or phone charger to confirm the disposal outlet has power.
3. Failed wall switch or loose switch wiring
If the outlet only works when the switch is on and the disposal stays dead while the rest of the kitchen is fine, the switch path is a strong suspect.
Quick check: Test the switched outlet with another small device while flipping the switch on and off.
4. Failed garbage disposal motor or internal wiring
If the outlet has power, the reset will not restore operation, and the disposal stays completely silent, the unit itself has likely failed internally.
Quick check: Confirm live power at the disposal outlet first. If power is present and the disposal remains dead, the disposal is the likely failure.
Step-by-step fix
Step 1: Make sure you are dealing with a dead disposal, not a jammed one
A humming disposal and a silent disposal point in different directions. You do not want to chase electrical problems when the unit is actually jammed.
- Turn the wall switch on briefly and listen closely.
- If you hear a hum, buzz, or feel slight vibration, turn the switch back off right away.
- If there is no sound at all, continue with the power checks below.
- If the sink is wet, dry the area under the cabinet before touching outlets, plugs, or the disposal body.
Next move: If you confirmed it is completely silent, you are on the right page. If it hums or tries to start, treat it as a jam or seized disposal instead of a no-power issue.
What to conclude: Dead silent usually means the reset tripped, the outlet lost power, the switch failed, or the disposal failed internally.
Stop if:
- You smell burning insulation or see melted plastic near the plug or switch.
- Water is dripping onto the outlet, plug, or disposal wiring.
- The disposal body is cracked or leaking from the bottom.
Step 2: Press the garbage disposal reset button the right way
This is the fastest, safest fix and it is the most common after a stall or overload.
- Turn the wall switch off.
- Find the small reset button on the bottom of the garbage disposal.
- Wait a minute if the disposal was recently stalled or hot, then press the button once firmly.
- Turn the wall switch on and test the disposal for just a second or two.
- If it still does not run, turn the switch back off before moving on.
Next move: If the disposal starts normally, the motor overload had tripped. Run cold water and test with a light load. If the button will not stay in, or it resets but the disposal is still dead, keep checking the power supply.
What to conclude: A reset that restores operation points to an overload or temporary jam. A reset that changes nothing means the problem may be upstream or the disposal may have failed.
Step 3: Check the GFCI, breaker, plug, and outlet under the sink
A lot of dead disposals are really dead outlets. Under-sink outlets often share a GFCI with another kitchen location.
- Make sure the disposal plug is fully seated in the outlet.
- Look for a nearby GFCI outlet on the backsplash, island, under the sink, or in an adjacent kitchen area and press RESET.
- Check the electrical panel for a tripped breaker and reset it once if needed.
- Plug a small lamp or charger into the disposal outlet to see whether the outlet has power.
- If the outlet is controlled by the wall switch, test it with the switch both on and off.
Next move: If the outlet comes back to life and the disposal runs, the problem was upstream power loss, not the disposal itself. If the outlet stays dead, the issue is likely the GFCI, breaker circuit, outlet, or switch wiring rather than the disposal.
Step 4: Decide whether the wall switch is the problem
If the outlet only gets power through the switch, a bad switch can make the disposal look completely dead.
- With the disposal unplugged, test the switched outlet using a lamp or charger while flipping the wall switch on and off.
- If the test device never turns on, try another known-good outlet to confirm the device itself works.
- If the disposal outlet is always live and the disposal is plugged in directly, the wall switch may not be the issue.
- If the switch feels loose, spongy, or works only sometimes, leave it off and plan for switch diagnosis or replacement.
Next move: If another device works from the switched outlet, the switch path is probably okay and the disposal becomes the main suspect. If the switched outlet never energizes, the wall switch or its wiring is likely the fault.
Step 5: Replace the failed part or call for electrical help
By this point you should know whether the problem is lost power to the disposal or a disposal that has power but stays dead.
- If the outlet has confirmed power and the disposal remains completely silent after reset, plan on replacing the garbage disposal.
- If the outlet is dead or only works intermittently through the switch, repair the outlet, GFCI, breaker issue, or wall switch before replacing the disposal.
- If the disposal is old, trips reset repeatedly, or went dead after a burning smell, replacement is usually more practical than internal repair.
- After the repair, restore power, run cold water, and test the disposal with a short burst only.
A good result: If the disposal runs cleanly without tripping the reset or breaker, the repair path was correct.
If not: If a new or known-good power path still leaves the disposal dead, stop and have the circuit and disposal connection checked by a pro.
What to conclude: A live outlet plus a dead-silent disposal usually means the disposal has failed. A dead outlet means the electrical supply problem comes first.

FAQ
Why is my Moen garbage disposal completely dead with no sound?
Most of the time it is a tripped disposal reset, a tripped GFCI, a dead switched outlet, or a bad wall switch. If the outlet has power and the disposal still makes no sound at all, the disposal itself has likely failed.
Where is the reset button on a garbage disposal?
It is usually a small button on the bottom of the disposal body. Turn the wall switch off first, then press it once firmly after the unit has had a minute to cool.
If the disposal hums, is that still a no-power problem?
No. A hum means the disposal is getting power but the motor cannot turn freely. That usually points to a jam or seized unit, not a dead power supply.
Can a bad wall switch make the garbage disposal seem dead?
Yes. If the disposal outlet only gets power when the switch is on, a failed switch can leave the disposal completely silent. Testing the switched outlet with a lamp or charger is a quick way to check.
Should I replace the disposal if the reset button keeps tripping?
Usually yes, unless you find and clear a simple jam first. A disposal that repeatedly trips reset, smells hot, or stays dead even with confirmed outlet power is usually at the end of its useful life.
What if the outlet under the sink is dead too?
That points away from the disposal and toward the power supply. Check for a tripped GFCI outlet nearby, a tripped breaker, a bad outlet, or a bad wall switch before replacing the disposal.
