Whirlpool WFE515S0JS Oven: Self-Clean Door Locked... | appliancefaults.com

Technical Background:

The electronic oven control (EOC), or MCU, monitors the door lock switch and oven temperature sensor (RTD). When a self-clean cycle is initiated, the EOC sends voltage to the door lock motor to engage the lock. It then monitors the door lock switch to confirm the door is locked. The EOC also monitors the oven temperature sensor to ensure the oven reaches the required temperature for self-cleaning. If any of these components malfunction or the EOC detects an error, it may display the “Self-Clean Door Locked” error and prevent the door from unlocking.

Symptoms:

The range displays a “Self-Clean Door Locked” error message, even though the self-clean cycle was not initiated or has completed. The oven door remains locked and cannot be opened manually. The range may be unresponsive to button presses.

Possible Causes:

Faulty door lock motor/switch assembly
Defective oven temperature sensor (RTD)
Malfunctioning electronic oven control (EOC) / MCU
Wiring harness issue between the door lock and the EOC
Mechanical obstruction preventing the door from fully closing
Software glitch in the EOC requiring a reset

Solution:

1

Disconnect power to the range at the breaker panel.
2

Remove the range back panel using a 1/4-inch nut driver to access the door lock mechanism and EOC.
3

Inspect the wiring harness connecting the door lock assembly to the EOC for any signs of damage or loose connections. Use a multimeter to test for continuity.
4

Test the door lock motor. With the unit de-energized, use your multimeter to check the resistance across the motor terminals. An open or shorted circuit indicates a faulty motor.
5

Verify the oven temperature sensor (RTD) resistance. At room temperature (approx. 70F), it should read around 1080 ohms. Use a multimeter to check the RTD resistance.
6

If the wiring, motor, and RTD are good, suspect a faulty EOC. Replace the EOC with a new, pre-programmed unit or reprogram the existing one if possible.
7

Reassemble the range, reconnect power, and test the self-clean cycle.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures. Be aware of potentially high voltage (120V AC) when testing components.

Prevention:

Avoid overloading the oven during self-clean cycles. Regularly inspect the door seal for damage and replace if necessary. Do not force the door open if it is locked.

Expert Tip:

Try entering the service mode by pressing and holding the Bake and Broil buttons simultaneously for 3 seconds. Then navigate to the error code display and clear the error. This may temporarily release the door lock, but the underlying problem still needs to be addressed.

Frequently Asked Questions

•What is the correct resistance range for the oven temperature sensor (RTD) at different temperatures?

The RTD resistance varies with temperature. At 70F it's approximately 1080 ohms. You can find a temperature/resistance chart in the service manual, or online.

•How do I determine if the EOC is sending the correct voltage to the door lock motor?

Using a multimeter, carefully measure the voltage at the door lock motor terminals when the self-clean cycle is initiated. You should see approximately 120V AC. Be extremely cautious when working with live voltage.

•Where can I purchase a replacement EOC for this model?

You can purchase a replacement EOC from authorized Whirlpool parts distributors, appliance parts retailers, or online marketplaces like AppliancePartsPros or RepairClinic. Ensure the part number matches the original EOC.
