Teka Chattering Relay / Low Voltage to Motor

Disposal does not run, but a loud buzzing is heard from the Teka control box or relay area instead of the motor.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose neutral or live connection, Undersized wiring causing voltage drop, Failing relay contacts, Shared circuit overloaded

Safety first: Turn OFF power at the breaker. Buzzing relays can overheat.

Step 1 – Inspect wiring connections: Check all screw terminals and wire nuts in the control box and junction box for tightness.
Step 2 – Check circuit load: Ensure the disposal is not on a heavily loaded circuit. Turn off other appliances and test again.
Step 3 – Replace relay/control: If buzzing persists with proper voltage and wiring, the relay or control module is likely defective and should be replaced.
