Understanding the Problem
Top-load washers use a lid safety switch (sometimes called a lid switch, lid latch, or safety interlock) to detect whether the lid is closed. If the switch is faulty or its actuator/cam is damaged, the washer may refuse to start, fail to agitate, not enter the spin cycle, or stop mid-cycle. The switch prevents the washer from running with the lid open for safety reasons, so even an intermittent failure will stop normal operation. Diagnosing the issue is usually straightforward: the washer behaves as if the lid is open even when it’s clearly closed, or it works only when you press on the lid or switch location. Faults can be caused by a broken plastic actuator, worn internal switch contacts, damaged wiring, or a failed control board that doesn’t read the switch. Replacing the lid switch assembly or actuator usually resolves the problem, but always confirm the electrical continuity and wiring integrity before replacing parts.
Common Symptoms
Washer won't start, won't agitate, won't spin, stops mid-cycle, intermittent operation, or the control panel shows an 'Lid' or similar error. You may hear no click when closing the lid.
Common Causes
- Broken or worn lid switch (internal contacts failed)
- Damaged or missing plastic actuator/cam that depresses the switch
- Frayed or disconnected wiring/harness or corroded connector

Helpful Repair Tip
Press the lid down while the washer is plugged in and try a short cycle; if it runs only while pressed or you can hear the click when closing the lid, test the lid switch for continuity with a multimeter (power disconnected). If no continuity when closed, replace the lid switch or actuator.
Frequently Asked Questions
How do I test the lid safety switch?
Unplug the washer. Access the switch (usually under the top panel or behind the control console). With the switch disconnected, use a multimeter on continuity or resistance mode. Close or depress the actuator while testing: a good switch shows continuity (near 0 ohms) when closed and open circuit when released. If there’s no continuity when closed, replace the switch.
Can I bypass the lid switch to make the washer run?
Bypassing the lid switch is not recommended and is a safety hazard — it defeats the device that prevents operation with the lid open. For testing only, a momentary jumper can show whether the switch is the problem, but never leave a bypass in place. The correct fix is to replace the faulty switch, actuator, or wiring.
