Understanding the Problem
The lid (or door) switch on Kenmore top-load washers is a safety interlock that tells the washer when the lid is closed so the machine can begin filling, agitating, or spinning. When this switch fails the washer may not start a cycle, may not agitate or spin, or may behave intermittently — even though power and the control board seem fine. The switch can fail electrically (open circuit), mechanically (worn actuator or broken plunger), or from damaged wiring/connectors. Diagnosing the lid switch is straightforward and usually the first step when the washer won’t start, won’t agitate, or won’t spin. With the washer unplugged you can access the switch near the lid hinge or under the top panel, inspect the actuator/strike and wiring for damage, and test for continuity with a multimeter while actuating the switch. If the switch shows no continuity when pressed (or continuity is intermittent), replacing the lid switch assembly (part 3949238) commonly resolves the problem. Also consider inspecting the lid strike/actuator and wiring harness — sometimes the switch is fine but the actuator that presses it is broken.
Common Symptoms
Washer won’t start, won’t agitate, won’t spin, cycle stops when lid is closed/opened, or intermittent operation tied to lid position.
Common Causes
- Failed lid/door switch (open circuit or intermittent contact)
- Broken or worn lid actuator/strike that doesn't depress the switch
- Damaged wiring or connector to the switch (loose, corroded, or frayed)

Helpful Repair Tip
With the washer unplugged, press the lid switch with a screwdriver or your finger while measuring continuity with a multimeter; no steady continuity when pressed indicates a bad switch.
Frequently Asked Questions
How do I test the Kenmore washer lid switch (3949238)?
Unplug the washer, access the switch, disconnect its connector, and use a multimeter set to continuity or ohms. Manually press the switch actuator; the meter should show continuity (low resistance) when the switch is pressed and open (no continuity) when released. If readings are open or jumpy while actuating, the switch is faulty.
Can I replace the lid switch myself and how hard is it?
Yes — replacing the lid switch is typically a straightforward DIY job for most top-load Kenmore washers. Unplug the washer, open or remove the top panel to reach the switch, disconnect the wire harness, remove mounting screws, swap in the new switch (3949238), reconnect wires, and test. Take photos of the wiring before removal and follow model-specific instructions if available. If wiring is damaged or the actuator/strike is broken, replace those parts too or consult a technician.
