Oven Sensor and Door Switch Test

Note

: See

Lock Assembly

for an explanation of the door switch function.

Remove power from the oven.

Make resistance measurements from the side of the sensor and the lock switch connector with exposed

terminals.

The resistance measurements are made on the logic board at the connector listed on the chart below.

If an abnormal reading is observed, wiggle the leads at the disconnect block. If there is any variation,

replace the component.
