Roper Washer Lid Lock Clicking But Not Engaging:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) sends a 120V AC signal to the lid lock solenoid. This voltage activates the solenoid, extending a locking mechanism that secures the lid. A sensor within the lid lock switch then communicates back to the MCU, confirming that the lid is locked, allowing the wash cycle to proceed. If the voltage path is interrupted, the lid lock fails, and the MCU will likely prevent the washer from running.

Symptoms:

The Roper washer starts, and you hear a clicking sound coming from the lid lock area, but the lid remains unlocked. The washer will likely not proceed to the wash cycle. The display may or may not show an error code.

Possible Causes:

Faulty lid lock switch
Defective Main Control Unit (MCU)
Wiring harness issue between the MCU and lid lock
Obstruction preventing the lid from fully closing
Worn or damaged lid strike
Low voltage to the lid lock mechanism

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Access the lid lock switch. This typically involves removing the top panel or control console using a 1/4-inch nut driver.
3

Inspect the wiring harness connected to the lid lock switch for any loose connections or damaged wires.
4

Use a multimeter to test the voltage at the lid lock connector. You should measure approximately 120V AC when the washer is attempting to lock.
5

If there is no voltage, check the continuity of the wiring between the MCU and the lid lock switch.
6

If voltage is present but the lock still doesn't engage, replace the lid lock switch.
7

Reassemble the washer and test the lid lock function.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. High voltage is present within the washer's electrical system. Follow Lock Out/Tag Out (LOTO) procedures to prevent accidental re-energization.

Prevention:

Periodically inspect the lid strike and surrounding area for any obstructions or damage. Avoid slamming the lid, as this can stress the locking mechanism. Clean the lid lock area with a damp cloth to remove any debris.

Expert Tip:

Some Roper washers have a service mode that allows you to manually test the lid lock function. Consult the service manual for the specific sequence. You can sometimes force the MCU to re-try the lid lock sequence in service mode.

Frequently Asked Questions

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

The service mode access varies by Roper model. Typically, it involves pressing a specific sequence of buttons on the control panel within a short time frame. Consult the technical sheet located inside the washer cabinet (usually behind the front panel) or search online for your specific model number.

•What resistance should I expect to measure across the lid lock switch terminals when it's locked?

When the lid lock is engaged, the resistance across the appropriate terminals (consult the wiring diagram) should be near zero ohms, indicating a closed circuit. When unlocked, the resistance should be very high, approaching infinity, indicating an open circuit. A reading between these values suggests a faulty switch.

•Where can I find the wiring diagram for my Roper washer?

The wiring diagram is usually located inside the washer cabinet, often attached to the back panel or control console. It's a folded sheet with all the electrical connections detailed. If it's missing, search online using your model number to find a downloadable version.
