My Disposal Has No Power

 
This article reviews the most common reasons a Moen garbage disposal won't get power.
 
1. Confirm Activation Method
Moen garbage disposals can be powered on by a variety of activation methods. The following are the most common:
Wall Switch

A switch on the wall that you can flip on and off to operate the garbage disposal. It is generally located on the wall behind or near the sink. the switch needs to be wired to a dedicated outlet. 

Batch Feed

Is the stopper being used to turn on the garbage disposal? The stopper activates an internal cherry switch that is built into the side wall of the housing. If the cherry switch gets stuck or breaks the unit will not turn on.

Fiber Optic Switch

This type of switch looks like a sink hole cover that you press to activate the garbage disposal. There is a fiber optic cable that runs from the above deck switch to the outlet below. Confirm that it is connected and not damaged. Fiber optic switches had a one year warranty and are obsolete. It is recommended that they be replaced with an air switch (ARC-4200 and AS-4201-finish).

Air Switch

This type of switch has a visible button in the center that is pressed to activate the garbage disposal. There is a tube that runs from the above deck air switch button to the outlet below. Confirm that it is connected and not damaged. Reconnect or replace if necessary.

2. Check Power Source
The garbage disposal must be getting power to operate.

Test the outlet to make sure that it is getting power. Plug another electrical device (ex: hairdryer, lamp, or cell phone charger) into the outlet to see if it works.

Does the electrical device get power?

Yes it does: Plug the garbage disposal back in and push the red reset button. The reset button is located on opposite side of the power cord. Test the garbage disposal to see if it works. If the garbage disposal does not turn on it may need to be replaced. 

No it does not:

  1. Examine the electrical service panel for the house. Depending on the style of the box, a breaker may have tripped or a fuse may need to be replaced.
  2. Re-test the outlet with another electrical device (ex: hairdryer, lamp, or cell phone charger) to see if it now works. Does the electrical device get power?
    • Yes it does, plug the garbage disposal in and push the red reset button (located on opposite side of the power cord). Test the garbage disposal to see if it works. If the garbage disposal does not turn on it may need to be replaced. 
    • No it does not, the outlet is broken which may require an electrician to replace it.

3. Motor Reset

Moen garbage disposals have a reset button that can be used if the internal breaker has been tripped.

To reset the internal breaker:

  • Push the red reset button. The reset button is located on the opposite side of the power cord. If the garbage disposal does not turn on, it may need to be replaced.

4. Garbage Disposal Is Jammed
If the garbage disposal was experiencing movement issues prior to having no sound/no operation, the garbage disposal may be jammed. In situations where the garbage disposal has become jammed, the internal breaker may have tripped. Follow the steps below for instructions on how to remove a foreign object(s), free the turntable and reset the garbage disposal.
1. Unplug the garbage disposal or if the garbage disposal is hardwired, turn the power off at the electrical box.
2. Once the power is disabled, remove the splash guard.

3. Using a flashlight, check for any foreign object(s) lodged between the turntable and grind ring.
4. Verify that the power is off. Using tongs or needle nose pliers, remove the foreign object(s). Never place your hand in the garbage disposal. Always use tongs or needle nose pliers to remove an object. Once the foreign object(s) has been eliminated, use a wooden spoon or the un-jamming wrench, Moen Part #1037 to rotate the turntable, in either direction so that it moves freely once again.

5. Based on the activation method, make sure garbage disposal switch is off. Go under the sink and press the red reset button. The reset button is located on opposite side of the power cord. Depending on the garbage disposal, the reset button may be set back slightly and may require a screwdriver to push it.
