Possible Causes
Loose wire nut in junction box, Loose plug in receptacle, Broken conductor in power cord, Loose internal connection at motor terminals
How to Fix / Troubleshooting
Safety first: Turn off the breaker before touching wiring or the unit.
- Check plug and outlet: For corded units, ensure the plug fits snugly. Replace a worn outlet that allows movement.
- Inspect junction box: For hardwired units, remove the wiring cover and tighten all wire nuts. Tug gently on each wire to ensure it is secure.
- Examine cord: Flex the cord gently along its length. If the unit cuts in and out when the cord is moved (with power off during testing), replace the cord.
- If problem persists: Internal connections may be loose. Replacement of the disposal is recommended.
