Kenmore Range Error Code F20

Error Code F20 indicates a lower oven door lock failure. This can occur due to various reasons, including loose or broken wire connections, issues with the door lock motor, or problems with the relay control board. Let’s break down the steps to diagnose and resolve this issue:

1. Unplug the Range:

• Safety first! Always disconnect the power supply to your Kenmore range before attempting any repairs. This ensures your safety and prevents electrical accidents.

2. Inspect Wire Harness Connections:

• Begin by checking the wire harness connections between the lower oven door lock motor and the relay control board. Over time, these connections may become loose or wires may break. Reconnect any loose wires and repair any damaged or broken wires.

3. Examine Door Lock Switch Connections:

• Next, investigate the wire harness connections between the door lock switches and the oven control board. Loose or damaged wires can also trigger Error Code F20. Securely reconnect any loose wires and repair any that are damaged.

4. Measure the Resistance:

• To determine the condition of the lower oven door lock motor, you’ll need a multimeter. Set the multimeter to measure resistance (ohms) and check the motor’s resistance. A healthy motor should measure approximately 2,600 ohms.

5. Replace the Lower Oven Door Lock Assembly:

• If the resistance reading is infinite or significantly different from the expected 2,600 ohms, it’s an indicator that the lower oven door lock motor is faulty and needs replacement. Contact a professional technician to replace the lower oven door lock assembly.
