How to Replace 3949247 Washer Lid Switch Assembly on Whirlpool Kenmore — Step-by-Step

Your Whirlpool LSR5232LQ0 won't start the spin cycle. The lid's closed, you can hear it click, but nothing happens. You press Start again. Still nothing. Before you call a repair tech charging $150 just to show up, check the lid switch assembly — it's the most common culprit when washers refuse to drain or agitate even though the lid seems fine.

The lid switch assembly is your washer's safety mechanism. When it fails, the control board thinks the lid is open and locks out the spin cycle to prevent injury. On models like the Kenmore 110.28803890 and Roper RAX7244JQ0, this part sees constant stress every time you close the lid. The plastic actuator gets brittle over the years, and one rough lid slam or unbalanced load that shakes the cabinet can snap it completely.

What You Need Before Starting

This is one of the easier washer repairs you'll tackle. Here's what to grab:

• Nutdriver set (usually 1/4" or 5/16")
• Flathead and Phillips screwdriver
• Flashlight or work light
• Towel (to protect the washer top)

Repair Time: Less than 15 minutes
Difficulty: Easy

One user who installed this part said: "I followed the repair video and everything was fine the switch change went without a hitch." That's the experience most people have — it's straightforward if you take your time.

Safety First

Unplug the washer from the wall outlet before you start. Don't just turn off the cycle — physically disconnect the power. You'll be working near electrical connections, and even though the voltage isn't huge, you don't want any surprises. Also, pull the washer away from the wall enough to give yourself working room. These top-load washers are heavy, so get help if you need it.

Step 1: Remove the Washer Top Panel

Locate the two screws at the back corners of the washer top, just under the control panel overhang. Use your nutdriver to remove them. Once they're out, push the top panel backward about an inch — it slides on clips — then lift up. Rest it against the wall on a towel so you don't scratch the finish.

Step 2: Locate the Lid Switch Assembly

The lid switch assembly mounts on the right side of the cabinet, near the front corner. It's a black or white plastic housing with two or three wire connectors attached. Look for the plastic actuator arm that sticks up — that's what the lid strikes when you close it. If yours is cracked or broken off, you've confirmed the problem. On the Whirlpool LSB6300PW2 and similar models, you might see wear marks where the lid's been hitting it for years.

Step 3: Disconnect and Remove the Old Switch

Press the locking tabs on each wire connector and pull them straight off. They're usually tight, so don't yank — work them back and forth gently. Once the wires are free, remove the mounting screws holding the switch assembly to the cabinet. Most use two Phillips head screws. The whole assembly will come out as one piece.

Step 4: Install the New 3949247 Switch Assembly

Position the new switch in the mounting holes. Make sure the actuator arm is pointing toward where the lid will strike it — there's really only one way it fits, but double-check before you screw it down. Install the mounting screws and tighten them snug, but don't overtighten and crack the plastic housing. Reconnect the wire harnesses until you hear them click into place.

Step 5: Test Before Reassembling

Before you put the top back on, plug the washer in and run a quick test. Close the lid and start a spin cycle. The washer should immediately begin draining and spinning. Open the lid mid-cycle — it should stop within two seconds. That confirms your new switch is working correctly. If it doesn't stop, recheck your wire connections.

Once you've confirmed it works, unplug again, slide the top panel forward onto its clips, and reinstall those two back screws.

Testing After Installation

Run a complete wash cycle with a small load. Pay attention to these checkpoints:

• Washer starts agitating immediately when you close the lid and press Start
• Spin cycle begins without you having to jiggle or slam the lid
• Opening the lid mid-cycle stops all motion within 2-3 seconds
• No error codes appear on the display

The switch assembly controls more than just spin — it tells the control board the lid status for every cycle phase. So if your Kenmore 11010202000 had issues with not draining, not agitating, or the cycle not advancing, this replacement should fix all of them at once.

Frequently Asked Questions

Why did my lid switch fail in the first place?

The plastic actuator becomes brittle after years of use and temperature changes in your laundry room. When you close the lid roughly — or when an unbalanced load causes the washer to shake violently — that brittle plastic can snap. It's not a defect, just normal wear on a part that gets used hundreds of times per year.

Will this fix a washer that won't drain or agitate?

If the lid switch is your problem, yes. The switch tells the control board whether it's safe to run the motor and pump. When it fails, the washer thinks the lid is open and refuses to drain, spin, or agitate. However, if you've replaced the switch and still have those symptoms, you might have a separate issue with the motor coupling, belt, or drain pump.

Do I need to recalibrate anything after replacing the lid switch?

No. The 3949247 switch assembly is plug-and-play. Once you connect the wires and close the lid, the control board immediately recognizes it. There's no calibration mode or reset procedure needed on Whirlpool, Kenmore, KitchenAid, or Roper washers for this repair.
