Urgency: Medium

Possible Causes

Incompatible or unsuitable cookware

How to Identify: Pan is not magnetic (fails magnet test, bottom is warped, rough, or not flat against the cooktop surface.

Part: Cookware material and base

Mismatched pan size vs. induction coil zone

How to Identify: Pan diameter is significantly smaller or larger than the induction element, causing power coupling inefficiencies.

Part: Cookware-to-zone matching

Internal component degradation (coil or sensor)

How to Identify: Uneven heating persists despite proper cookware and clean surface, may include error codes or irregular power behavior.

Part: Induction coil or sensor circuitry

DIY Solutions

Use Induction‑Compatible Cookware

Easy 5–10 minutes

Check whether your cookware is induction compatible by using a magnet on the base; it should stick firmly.
Replace or switch to magnetic stainless steel, cast iron, or induction‑ready cookware with flat bottoms.
Match the pan size to the cooktop zone for better heat distribution.

⚠️ Safety First: Avoid dragging cookware across the glass surface to prevent scratches.

Clean Cooktop Surface

Easy 5–15 minutes

Tools Needed: soft cloth, gentle cleaner

Turn off the cooktop and allow it to cool.
Wipe away food residue, grease, or spills with a soft cloth and non‑abrasive cleaner.
Dry completely before using to ensure full contact between cookware and surface.

⚠️ Safety First: Do not use abrasive pads that can scratch the ceramic glass.
