Description
Product Overview
When your top-load washer fills with water but refuses to agitate or spin, the lid switch is the #1 suspect. The iFJF 3949238 (AP3100001) is a direct OEM-spec replacement safety interlock switch for Whirlpool-manufactured washing machines sold under the Whirlpool, Kenmore, Sears, Roper, Estate, Inglis, and Crosley brands. This 3-wire plunger-actuated switch tells the control board the lid is securely closed — enabling the motor to run for spin and agitation cycles. A failed switch typically means the washer fills with water but does nothing else. This 10-minute repair restores full function without a costly service call.
Key Features
-
3-Wire Pre-Terminated Connector — Plug-and-play design with the correct OEM-style connector preinstalled. No cutting, splicing, or crimping required — just unplug the old, plug in the new.
-
Wide Brand Coverage — Compatible with top-load washers from Whirlpool, Kenmore (Sears), Roper, Estate, Inglis, and Crosley — all manufactured by Whirlpool Corporation using the same lid switch design.
-
UL-Recognized Safety Interlock — This is a critical safety component that prevents the washer motor from running with the lid open. A properly functioning lid switch is essential for safe operation.
-
Plunger-Actuated Mechanism — The physical plunger is depressed by the lid striker, closing the circuit. Simple, reliable mechanical operation — no electronics to fail.
-
10-Minute DIY Repair — Two screws and one connector. No disassembly beyond removing the top panel (usually 2 spring clips or screws). Saves $150+ service call fees.

Why Choose This
A service call to diagnose and replace a lid switch typically costs $150-250. This exact OEM-spec replacement switch costs a fraction of that and takes 10 minutes to install with a basic screwdriver. The symptoms of a failed lid switch are unmistakable — the washer fills normally but sits there without agitating or spinning. Before you call a repairman or consider replacing your machine, try this $16 fix. Nearly every "washer fills but won't spin" complaint traces back to this $16 part. Backed by iFJF's quality guarantee.

Frequently Asked Questions
Q: My washer fills with water but won't agitate or spin. Is this the fix?
A: Very likely. On Whirlpool/Kenmore/Roper top-load washers, the lid switch must be closed (plunger depressed) for the motor to energize. If your washer fills normally but sits idle afterward, the lid switch is the most common cause. Replace the 3949238 to restore operation.
Q: Will this fit my Kenmore 110 series washer?
A: Yes. Kenmore model numbers starting with 110 are manufactured by Whirlpool and use this exact lid switch design. The 110-series prefix is the key identifier — if your Kenmore washer starts with 110, this switch fits.
Q: How do I test if my lid switch is bad before ordering?
A: Unplug the washer. Remove the top panel (typically 2 spring clips at the front corners). Locate the lid switch near the lid hinge. Use a multimeter on continuity mode — press the plunger in: should show continuity. Release: should show open circuit. If either test fails, replace the switch.
Q: My washer runs with the lid open. Do I need this?
A: YES — replace immediately. A washer that operates with the lid open has a failed (shorted) safety interlock, which is a significant safety hazard. The lid switch should prevent the motor from running when the lid is raised. Replace the 3949238 switch right away.
Q: How difficult is installation?
A: Easy DIY. Unplug the washer, remove the two spring clips holding the top panel (near the front corners), tilt the panel back, locate the lid switch near the hinge area, remove 2 screws, disconnect the wire connector, install the new switch, reassemble. Total time: 10-15 minutes.
Q: Does this switch fit front-load washers?
A: No. This is specifically for top-load washing machines with a lift-up lid mechanism. Front-load washers use a door lock assembly, which is a completely different part.
