KitchenAid Dryer Error Code E6

The E6 error code on a KitchenAid dryer indicates that the exhaust temperature has exceeded 190°F (87.7°C), which is above the safe operating threshold for the exhaust system. When this limit is reached, the dryer's control board immediately shuts off all outputs, including the heat source and drive motor, to prevent potential fire or component damage. This is a protective thermal event, not a simple sensor glitch, and the underlying cause must be resolved before the dryer can safely return to operation.

The exhaust temperature sensor monitors airflow conditions throughout the drying cycle. When airflow is restricted or the heating system is malfunctioning, heat accumulates in the drum and exhaust pathway, driving temperatures beyond the 190°F threshold. The primary diagnostic entry point for this code is TEST #3b, which is the exhaust thermistor or temperature sensor test, confirming whether the sensor is accurately reporting conditions or whether the temperature genuinely exceeded safe limits.

Common contributors to this fault include blocked exhaust venting, a failed cycling thermostat, a stuck or shorted heating element, or a faulty exhaust temperature sensor producing a false high-temperature reading. Because all outputs are disabled when E6 triggers, the dryer will not resume operation until the fault condition is cleared. Technicians should always inspect the full exhaust duct path from the dryer outlet to the exterior termination point before replacing any components.
