Roper Washer Lid Lock Light Flashing: Troubleshooting... | appliancefaults.com

Technical Background:

The MCU controls the lid lock mechanism and monitors its status through voltage feedback. When a wash cycle is initiated, the MCU sends voltage to the lid lock, engaging the solenoid and securing the lid. A signal is then sent back to the MCU confirming the lid is locked. If the MCU doesn't receive the correct feedback voltage or encounters an error during the locking process, it will flash the lid lock light and prevent the washer from starting. The system depends on proper voltages and continuity within the lid lock circuit.

Symptoms:

The homeowner reports that the lid lock light is flashing and the Roper washer will not start a wash cycle. The washer may attempt to fill with water, but the cycle will not progress.

Possible Causes:

Lid switch failure.
Faulty lid lock mechanism.
Wiring harness issue between the MCU (Main Control Unit) and the lid lock.
Defective MCU.
Obstruction preventing the lid from fully closing.
Drain pump malfunction.

Solution:

1

Unplug the washer from the outlet.
2

Visually inspect the lid switch and lid lock mechanism for any physical damage or obstructions. Remove any obstructions.
3

Using a multimeter, check the continuity of the lid switch. With the lid closed, the switch should show continuity. If not, replace the lid switch.
4

Locate the wiring harness connecting the lid lock to the MCU. Inspect for any frayed wires or loose connections. Repair or replace as needed.
5

Check the voltage at the lid lock connector. You should typically see 120V AC when the washer is attempting to lock the lid. Use caution.
6

If the wiring and lid switch are good, suspect a faulty lid lock. Replace the lid lock assembly.
7

If all other components test good, the MCU may be defective. Replacement of the MCU might be necessary, although this is less common.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. High voltage is present within the washer's electrical components. Exercise extreme caution.

Prevention:

Regularly inspect the lid area for debris or obstructions. Avoid overloading the washer, as this can put excessive stress on the lid lock mechanism. Ensure the washer is level to prevent uneven loads and potential lid issues.

Expert Tip:

Many Roper washers have a diagnostic mode. To enter it, rapidly rotate the cycle selector knob three clicks clockwise, then three clicks counter-clockwise, and then one click clockwise. Error codes may then be displayed via the cycle indicator lights.

Frequently Asked Questions

•What is the part number for the lid lock assembly?

The part number will vary depending on the specific model. You can find it on the washer's model number label or by searching online appliance parts retailers.

•How do I access the lid switch on this model?

Typically, you'll need to remove the top panel of the washer. This may involve removing screws at the back or side. Then, you can access the lid switch and its wiring.

•Is it possible to bypass the lid lock?

Bypassing the lid lock is not recommended due to safety concerns. The lid lock is designed to prevent the washer from operating with the lid open, which could lead to injury. It's always best to repair or replace the faulty component.
