How to Fix / Troubleshooting

Safety first: Unplug the cooker before opening any covers.

Steps to resolve:

Shake test (unplugged): Gently shake the cooker and listen for loose parts moving. This can help locate the source.
Open housing: Remove base and, if necessary, side/top covers. Look for loose screws, brackets, or shielding plates. Tighten or resecure them.
Inspect PCB components: If the noise seems electrical (buzzing), lightly press on larger components like transformers or inductors with an insulated tool while the unit is running (only if you are trained and understand the risks). If the noise changes, secure the component with non-conductive adhesive rated for electronics.
Check fan (if present): Some models have a small cooling fan. Ensure its blades are not hitting wires or plastic. Re-route wires and clean dust buildup.

Warning: Live testing inside the unit is dangerous and should only be done by qualified personnel.

Rattling or buzzing noise from inside the cooker during operation.
