What Performance Boost Flashing - Power Level Changes Means
Freestanding and slide-in Range with an induction cooktop: KitchenAid publishes this as the boost function working within its own limits rather than as a fault. The Performance Boost function operates only one cooking area in a cooktop zone, so if both areas in a zone are set for boost, the one set last keeps the boost power level and the other resets to a lower level. It adds that the function may also switch a cooking area to a lower setting to keep the cooktop from overheating, and states that you can continue to use the cooktop when the display is not flashing. It also asks you to ensure water or cooking utensils are not placed on the glass above the control unit, moving them and cleaning the surface.
Common Causes of Performance Boost Flashing - Power Level Changes
- Performance Boost set on both areas of the same cooktop zone
- The function dropping a zone to a lower setting to keep the cooktop from overheating
- Water or utensils left on the glass above the control unit
- A pan that is not suitable, not centred or overhanging the cooking area
🔧 One Safe Check You Can Try
Check first whether boost is set on two areas in the same zone, because the cooktop only holds it on one - the area set last - and the other drops back. Then check the glass above the control unit for water or utensils and move them, drying the surface. Confirm the pan suits the zone: a magnet should grip its base, the diameter should match the area, and it should be centred, with no more than about half an inch of overhang, since oversized pans reduce performance.
⚠ Why You Shouldn't Go Further Than That
- This is documented behaviour rather than damage, and the power level dropping is the cooktop protecting itself from heat it cannot shed quickly enough.
- Oversized pans reduce performance on induction, so chasing a boost that will not hold with the wrong pan is chasing something the cookware is causing.
- A freestanding range stands on its own feet and is held against tipping by a bracket at the floor, so pulling one out without releasing that bracket properly is how ranges come forward off their footing.
