Understanding the Problem
Many Kenmore top-load washers use a lid or door switch to detect when the lid is closed; the control board will not allow the washer to agitate or spin if the switch is open or reporting an error. Part number 3949238 is commonly referenced as a replacement lid/door switch for several Kenmore models. When the switch fails, the washer may refuse to start, stop mid-cycle, or behave inconsistently during agitation and spin. Failure can be caused by a worn internal contact, broken actuator plunger, damaged wiring or connector, or physical damage from impacts or rust. Before ordering parts, it’s important to verify the switch is the root cause by performing a simple visual and electrical test — otherwise the problem could be the harness, lid strike, or the control board itself.
Common Symptoms
Washer won’t start or won’t go into agitate/spin, cycles stop when lid closed/opened, intermittent operation only when lid slammed or pressed, no continuity at switch terminals with lid closed.
Common Causes
- Worn or burned internal contacts in the lid/door switch
- Broken or jammed actuator/plunger that doesn’t engage the switch
- Damaged wiring harness or corroded connector between switch and control board

Helpful Repair Tip
Confirm the switch before buying: with power disconnected, remove the switch and test its terminals for continuity with the lid closed (use a multimeter). Also perform a visual check for a broken actuator/plunger or burned contacts.
Frequently Asked Questions
How do I test the Kenmore lid switch (3949238)?
Disconnect power, remove the switch from the washer, and use a multimeter set to continuity or ohms. With the lid actuator depressed (or the plunger pressed), the switch should show continuity between the correct terminals. If it reads open (infinite resistance) when pressed, the switch is bad. Also inspect the plastic actuator for damage and the connector for burned pins.
Can I bypass the lid switch to make the washer run?
Temporarily bypassing the lid switch can be used for diagnosis only, but it is not recommended as a permanent fix because it defeats a safety feature and can be dangerous (risk of injury). If bypassing makes the washer run, replace the faulty lid switch and repair any damaged wiring rather than leaving it bypassed.
