Roper Washer Lid Lock Light Flashing: Meaning and Reset... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the status of the lid switch and lid lock mechanism. When the MCU detects an error, such as the lid not being properly locked, it signals the lid lock light to flash and prevents the washer from operating. Voltage is supplied to the lid lock solenoid to engage it. A sensor reports back to the MCU when locked.

Symptoms:

The homeowner observes that the lid lock light on their Roper washing machine is flashing continuously, and the washer will not start or continue its cycle.

Possible Causes:

Lid switch failure.
Faulty lid lock mechanism.
Obstruction preventing lid from closing completely.
Wiring harness issue between the control board and lid lock.
Main Control Unit (MCU) failure.
Motor control board issue.

Solution:

1

Unplug the washer from the wall outlet or turn off the breaker.
2

Remove the top panel of the washer using a 1/4-inch nut driver. Refer to the service manual for your specific model.
3

Inspect the lid switch and lid lock mechanism for any visible damage or obstructions.
4

Using a multimeter, check the continuity of the lid switch when the lid is closed. It should show continuity (close to 0 ohms).
5

Check the voltage going to the lid lock solenoid. It should read approximately 120V AC when the washer is attempting to lock the lid.
6

If the voltage is present but the lid lock is not engaging, the lid lock assembly is likely faulty and needs replacement.
7

If there is no voltage, check the wiring harness and connections between the control board and the lid lock. Repair or replace as needed.

Safety Warning:

Always disconnect the power to the appliance before performing any repairs. This appliance operates at 120V AC, which can cause serious injury or death. Use proper Lock Out Tag Out (LOTO) procedures before working on the appliance.

Prevention:

Periodically inspect the lid area for any obstructions and clean the lid switch and lock mechanism to ensure smooth operation. Avoid slamming the lid.

Expert Tip:

Some Roper washers have a diagnostic mode. Check your tech sheet glued inside the cabinet for the correct button sequence to enter diagnostic mode and retrieve error codes. This can narrow down the problem more quickly.

Frequently Asked Questions

•How do I access the diagnostic mode on my Roper washer?

The exact button sequence varies by model, but typically involves pressing certain buttons in a specific order within a short time frame. Consult the tech sheet located inside the washer cabinet or search online using your model number.

•Where is the lid switch located?

The lid switch is usually located near the lid hinge or on the cabinet where the lid makes contact when closed. It's designed to detect when the lid is closed.

•What if the lid lock light is still flashing after replacing the lid lock assembly?

If the issue persists after replacing the lid lock, there may be a problem with the wiring harness, the control board, or possibly a grounding issue. You'll need to perform further electrical testing and trace the wiring to identify the root cause.
