KitchenAid Cooktop Error Code F4
The pot or pan is too close to the control panel; NTC temperature of the touch control is excessively high…
The pot or pan is too close to the control panel; NTC temperature of the touch control is excessively high (>100°C). If F4 appears, none of the 4 cooking zones will work.
First step from the service manual
Make sure the pot or pan is centered on the surface cooking area and nothing hot is on the touch control panel. Wait 5 minutes for control panel to cool.

What F4 means on a KitchenAid cooktop
The F4 error code on a KitchenAid induction or touch-control cooktop indicates that the NTC (Negative Temperature Coefficient) thermistor embedded in or near the touch control panel has detected a temperature exceeding 100 degrees Celsius. The NTC thermistor is a resistive sensor whose resistance drops as temperature rises, and the cooktop's control board continuously monitors this resistance to protect the sensitive electronics beneath the glass touch interface. When the board reads a temperature above the 100 degree threshold, it immediately locks out all four cooking zones as a protective measure, preventing any further heat generation until the condition is resolved.
The most common trigger for F4 is improper cookware placement. If a pot or pan is positioned too close to the control panel area rather than centered on the designated cooking zone, residual heat, steam, or direct radiant heat from the cookware can elevate the temperature of the touch control region rapidly. The glass surface in the control zone does not have active cooling, so heat accumulates quickly when a hot vessel is nearby.
Once the F4 code appears, the cooktop enforces a complete shutdown of all cooking zones regardless of their individual settings. This is by design, as overheating the touch control electronics can cause permanent damage to the control board. The lockout remains active until the NTC sensor reads a safe temperature again, which typically requires a cool-down period of approximately five minutes after the heat source is removed.

Common causes of F4
- 01
Cookware too close to the control panel
Wiring / connectionA pot or pan positioned near the edge of a cooking zone can radiate or conduct heat directly into the touch control area, pushing the NTC sensor above 100 degrees Celsius. Check that all cookware is centered on its designated cooking zone and not overlapping toward the controls.
- 02
Hot item placed on or near the touch panel
Wiring / connectionSetting a hot lid, pot, or other warm object directly on the touch control panel area traps heat against the glass and rapidly elevates the NTC sensor temperature. Remove any objects from the control surface and allow the area to cool.
- 03
Spillover or boilover near the control zone
Wiring / connectionHot liquid that boils over and flows toward the control panel can transfer significant heat to the touch control area. Clean up any spills carefully and allow the surface to cool fully before attempting to restart.
- 04
Faulty NTC thermistor
Part replacementIf the F4 error appears without any obvious heat source near the control panel, the NTC thermistor itself may have drifted out of calibration or failed, causing the control board to read a falsely high temperature. Diagnosing this requires measuring the sensor's resistance output and comparing it to expected values for ambient temperature.
- 05
Defective control board
Part replacementA failing control board may misinterpret the NTC thermistor signal and trigger F4 even when actual temperatures are within normal range. This is less common and should only be considered after confirming the thermistor and cookware placement are not the root cause.
