Servicing Worn Impellers:
To remove a garbage disposal to sharpen impellers:
- Unplug the garbage disposal, remembering to trip the circuit breaker first or remove the fuse at the main electrical box if the disposal is wired directly into the house. (Circuit breakers act to limit the current in a single circuit in most household applications. Typically a single circuit is limited to 20 amperes, although breakers come in many sizes.)
- Remove all hose fittings leading into or away from the disposal. Some garbage disposals can then be removed by twisting to free them from the support ring. Others require that the unit be unscrewed from the ring.
- Remember that a garbage disposer is a relatively heavy small appliance, so freeing it will suddenly put its full weight in your hands.
- To service worn impellers on many models, you must remove the flywheel. Lock the flywheel in place with a screwdriver, then loosen the flywheel lock nut.
- Once the flywheel is removed, the impellers can be removed or sharpened in place. If the impellers cannot be sharpened, the flywheel assembly will need to be replaced
Garbage disposal maintainence requires some knowledge of plumbing as well as electrical work. If you are not sure of your abilities, a plumber can help.
