Roper Washer Lid Lock Bypass: Using a Magnet -... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the lid switch and controls the lid lock solenoid. When the start button is pressed, the MCU checks the lid switch status. If the lid is closed, the MCU energizes the lid lock solenoid, securing the lid. A feedback signal from the lid lock confirms the lock is engaged before the wash cycle starts. The voltage to the lid lock is typically 120V AC.

Symptoms:

US homeowner observes the washer will not start, the lid lock indicator flashes, or they are trying to bypass the lid lock with a magnet.

Possible Causes:

Damaged lid lock assembly
Faulty lid switch
Wiring harness issue
Defective Main Control Unit (MCU)
Attempting to bypass the lock with external magnets (Not Recommended)
Loose wiring connections to the lock solenoid.

Solution:

1

Disconnect power to the washer at the breaker panel. Lock Out/Tag Out (LOTO) procedure.
2

Inspect the lid lock assembly for physical damage. Remove the top panel using a 1/4-inch nut driver and examine the lock mechanism. Replace if damaged.
3

Using a multimeter, check the continuity of the lid switch. It should be closed when the lid is closed. Disconnect the wires to the switch before testing. Resistance should read near 0 ohms when closed and infinite when open.
4

Verify the wiring harness connections to the lid lock and MCU. Repair any loose or damaged wires. Use a wiring diagram to trace the wires.
5

Check the voltage to the lid lock solenoid (typically 120V AC during the spin cycle). Use extreme caution! Ensure you are using a CAT III rated meter and standing on a dry surface.
6

If voltage is present and the lock is not engaging, replace the lid lock assembly. Order the correct replacement part based on the model number.
7

If no voltage is present, suspect a faulty MCU. Replacing the MCU often requires programming with the correct software for the specific model.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present inside the washer. Use extreme caution when working with electrical components. Always follow Lock Out/Tag Out (LOTO) procedures.

Prevention:

Avoid slamming the lid. Regularly inspect the lid lock assembly for wear and tear. Ensure the washer is level to prevent excessive vibration that can damage the lock mechanism.

Expert Tip:

Some Roper washers have a diagnostic mode. To enter diagnostic mode, quickly press and release the start button 3 times within 5 seconds while the washer is idle. This may display error codes related to the lid lock system.

Frequently Asked Questions

•How do I access the lid lock assembly on my Roper washer?

Typically, you'll need to unplug the washer, remove the screws securing the top panel (usually at the back), and then slide the top panel back or up to release it. The lid lock assembly will then be visible and can be removed by disconnecting the wiring harness and removing the mounting screws.

•What does a flashing lid lock light indicate?

A flashing lid lock light often indicates an error related to the lid lock system. It could mean the lid switch is not registering correctly, the lid lock solenoid is failing to engage, or there's a communication issue between the lid lock and the main control board. Consult the service manual for specific error code definitions.

•How do I test the lid lock solenoid?

After disconnecting power, use a multimeter to measure the resistance of the solenoid coil. A reading of infinity or zero ohms indicates a faulty solenoid. You can also apply voltage (if known and safe) to the solenoid to see if it actuates, but always refer to the service manual for correct voltage specifications. If the resistance is good but it doesn't engage, it needs replacing.
