8.2.4.2 Garbage Disposal Air Switch service
The garbage disposal is operated via an air switch. This is a safety device that enables the disposal to be turned on with
an air pulse versus running electricity.
• Check that the air switch is functioning properly. Make sure it pushes in completely and does not stick due to
debris or grim buildup. Verify the air line connection at the push button and the switch.
