Garbage disposal makes a chattering or rapid clicking noise when switched on but does not spin.

Safety first: Turn off power before opening any covers.

• Check for jams: Confirm the impeller plate rotates freely with the hex key. If jammed, clear as per standard procedure.
• Inspect capacitor: On models with an external capacitor, replace it with a Rangemaster-approved part if there are signs of bulging or leakage.
• Listen to control module: If the clicking comes from a small control box on the unit, the relay may be chattering due to low voltage or internal failure. Have an electrician verify supply voltage.
• Replace control/motor: If voltage is correct and a new capacitor does not resolve the issue, the control PCB or motor is likely faulty. Replacement of the disposal is recommended.
