Understanding the Problem
What the Maytag lid switch is and why it matters: The lid switch (aka lid lock, lid actuator, plunger or strike) is a safety interlock on Maytag top‑load washers that tells the machine the lid is closed and allows the washer to agitate and spin. When the switch or its actuator fails the washer may not start, won’t spin or agitate, stops mid‑cycle, or in rare cases will run with the lid open. Step-by-step diagnosis and repair (practical): 1) Confirm the symptom - Try to start a cycle with an empty tub. Note whether the washer: (a) does nothing, (b) fills then won’t agitate/spin, (c) stops mid‑cycle, or (d) shows a lid lock light that never changes. 2) Basic quick checks - Make sure the washer is plugged in and the circuit breaker is on. - Move the lid slowly and listen for a soft click near the lid hinge area when you open/close the lid. 3) Access the lid switch - Unplug the washer. For top‑load Maytags, open the lid, remove the screws at the back of the top panel, then tilt the top up (some models have clips at the front). Locate the plastic switch or metal strike on the underside of the lid or on the cabinet rim. 4) Visual inspection - Inspect the plunger/actuator and the switch body for broken plastic, melted plastic, corrosion, or a missing strike. Check the wiring harness and connector for burns, loose pins, or frayed wires. 5) Functional test with the lid - With the washer unplugged, press the plunger/actuator by hand. It should move smoothly and spring back. If it’s stuck or too loose, it’s likely bad. 6) Continuity test (recommended) - Set a multimeter to continuity/ohms. Unplug the harness from the switch. Probe the switch terminals and press the plunger. A good switch will show continuity only when plunger is depressed (or only when released, depending on switch type). No change = bad switch. 7) Replace the part - Order the correct part for your model (common part numbers below such as WP22001682, WP22002754, WP8318084, WP3949238, WPW10240513, 12001908, 279347). - With power off: remove the top panel, unplug the switch harness, remove mounting screws/clips, and take out the old switch/actuator. - Install the new switch/actuator, reconnect the harness making sure pins seat fully, secure the switch, lower and fasten the top panel. - Restore power and run a test cycle. 8) What if replacement doesn’t help - Recheck wiring continuity between the harness connector and the control board. If wiring is good and new switch still fails, the control board or harness connector may be faulty. Safety note: Always unplug the washer before testing or replacing the lid switch. Do not operate the washer with a bypass in place — it defeats a critical safety device and can cause injury.
Common Symptoms
Washer won't start or won't progress to agitate/spin; washer stops mid‑cycle; lid lock light stays on or never engages; loose or broken plastic plunger/strike under the lid.
Common Causes
- Failed lid switch assembly (worn contacts or broken switch)
- Broken/misaligned lid plunger, actuator or strike (plastic parts wear or snap)
- Damaged wiring or connector between the switch and the control board

Helpful Repair Tip
With the washer unplugged, press and release the lid plunger while listening for a distinct click; then use a multimeter on the switch terminals—you should see continuity change only when the plunger is pressed (or released depending on model).
Frequently Asked Questions
How can I tell if the lid switch is bad or if it’s the control board?
Start with the lid switch: visually inspect for broken plastic or melted parts, then test the switch with a multimeter for continuity while pressing the plunger. If the switch shows no continuity change, replace it. If the new switch behaves the same and wiring continuity back to the control board is good, suspect the control board or its connector. Always confirm wiring and connector pins before condemning the main control.
Can I bypass the lid switch so my washer will run?
You can temporarily jumper the switch terminals for a quick diagnostic to see if the washer will start, but DO NOT operate the washer with the switch bypassed. Bypassing removes a critical safety interlock and risks injury. If the jumper test makes the washer run, replace the lid switch/actuator assembly—do not leave a bypass in place.
