KitchenAid Range Error Code F6 E1

The F6 E1 error code on a KitchenAid range indicates an over-temperature condition detected during cook mode, commonly referred to as a runaway temperature fault. This means the oven cavity temperature has exceeded safe operating limits without a corresponding command from the control board to increase heat. The control board continuously monitors temperature through the oven temperature sensor (RTD probe) and compares actual cavity temperature against the target setpoint. When the measured temperature climbs beyond acceptable thresholds without correction, the board flags this fault to prevent potential damage to the oven cavity, wiring, or surrounding cabinetry.

The most common technical cause is a relay on the control board that has failed in the closed position, allowing continuous voltage to the bake, broil, or convection element even when the board is not actively calling for heat. Diagnostics involve entering the service mode and cycling the bake, broil, and convect relays individually to verify proper element operation. Voltage at connector P6 pins 1 through 5 should read 120V AC when the corresponding relay is energized and drop to zero when the relay opens. If voltage remains present at any of these pins when the relay should be off, the control board is the likely culprit.

A faulty oven temperature sensor can also produce this fault by sending an inaccurately low resistance reading to the control board, causing it to misinterpret the oven as cooler than it actually is and continuing to energize the elements. Additionally, physical damage to the sensor wiring or a shorted sensor probe can result in false temperature data that triggers runaway behavior. Confirming the sensor is within its proper resistance range at room temperature is an early step in isolating the root cause.
