Redmond Abnormal Electrical or Mechanical Noise

Unusual loud clicking, popping, or buzzing noise from the base during heating.

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 heating plate mounting screws, Arcing at heater connectors, Failing relay on control board

Safety first: Unplug the cooker and let it cool before opening.

Check mounting: Remove the inner pot and gently press on the heating plate. If it moves or rattles, tighten the mounting screws from underneath.
Inspect connectors: With the bottom cover removed, look for darkened or loose heater connectors. Clean and tighten or replace as needed.
Listen to relay: Some clicking from a relay is normal, but rapid or loud chattering may indicate a failing relay or control issue. In that case, the PCB should be inspected and likely replaced.
