Frigidaire Gallery Induction Cooktop Uneven Heating: Pan or Zone?

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   With the cooktop off and the pan cool enough to handle, inspect the pan base and the cooking surface for a visible wobble, heavy residue, a rough or damaged base, or a crack in the glass. Use a household magnet on the pan base if the exact Gallery manual does not prohibit that check, and record whether it sticks across the usable base.

   Expected result: The base is flat, clean, stable, and magnetic, or it is warped, very light, rough, damaged, nonmagnetic, or visibly contaminated.

   Next step: Repeat the comparison with a known induction-suitable, flat, medium-to-heavy pan. If the pan is damaged or unsuitable, replace the cookware only after confirming the exact manual's requirements; do not diagnose an internal part from this result.

   Stop if: Do not slide rough cast iron across the glass, polish a damaged surface with abrasive material, or test a cracked cooktop under power.

   Why this matters

   Why: Frigidaire recommends heavy-gauge induction cookware and uses magnetic detection to identify suitable material. A pan that is not flat, stable, or consistently magnetic can transfer heat unevenly even when the zone itself is operating.

2. Check 2

   Centre one suitable pan on the marked zone and compare its base diameter with the zone marking. Use the same pan, the same food quantity, and the same preparation on one other zone when the cooktop is safe to use; stop the heat before moving a hot pan. Note whether the pan is smaller than the active area, overhangs it, or sits off-centre.

   Expected result: The pan is centred and appropriately sized, or the uneven result changes when the pan size or position changes.

   Next step: Use the exact Gallery manual's zone and cookware guidance and keep the pan centred. If the same setup remains uneven, continue with the pan-versus-zone comparison instead of simply raising the power level.

   Stop if: Do not move a pan while oil or boiling liquid is unstable, bridge zones, or use an improvised metal plate to enlarge the active area.

   Why this matters

   Why: Frigidaire says pan-size recognition adapts induction zones to pan sizes for more even cooking, while its support guidance says cookware affects heat distribution. A result that changes with size or position points first to cookware coupling or transfer rather than a confirmed failed zone.

3. Check 3

   Compare the same suitable pan and a repeatable, low-risk cooking setup on a second zone. Observe whether the hot and cool pattern follows the pan when the pan is moved, stays in the same part of the pan on different zones, or remains tied to one marked zone. Do not use bare hands to judge temperature and do not deliberately overheat oil.

   Expected result: The pattern follows the pan, changes with position or pan size, or stays with one zone across a suitable pan and the same setup.

   Next step: For a pan-following result, correct the cookware or cooking setup. For a zone-following result, record the zone, pan, setting, and result, then arrange qualified Frigidaire or appliance service rather than opening the cooktop.

   Stop if: Stop the comparison for smoke, sparking, electrical odor, cracked glass, a hot control area, or any sign that the pan or cooktop is overheating abnormally.

   Why this matters

   Why: A pan-following pattern makes cookware or heat transfer more likely. A pattern that stays with one zone after a controlled comparison raises a zone-specific sensing or power issue, but it still does not identify a replaceable part without model-specific diagnosis.

4. Check 4

   Separate normal induction behavior from a cooking defect. During one supervised use of a suitable pan, note whether the pan heats while the glass stays comparatively cooler and whether there is a hum, buzz, click, or fan sound. Compare that with the actual food result and with any display, lock, no-pan, or error indication.

   Expected result: The pan heats and the food result improves with a suitable pan, or the pan remains cold, the zone reports an error, the cycle stops, or the uneven result is unchanged across suitable pans.

   Next step: If cooking is even with suitable cookware, continue using the exact Gallery manual. If the pan stays cold, the zone shows an error, or unevenness stays with one zone, stop user testing and arrange qualified service.

   Stop if: Do not remove the glass, test live inverter or coil wiring, bypass pan detection, or keep increasing heat to force a response.

   Why this matters

   Why: Frigidaire identifies humming, buzzing, clicking, and a cooler induction surface as normal possibilities. Persistent uneven cooking with suitable cookware, especially when confined to one zone, is different from those normal sounds and needs model-specific assessment.
