What the lid switch does and why it fails
The lid switch on a Whirlpool washer is a small plastic and metal part mounted under the lid or on the frame near the lid. When you close the lid, the switch tells the washer it is safe to start filling and spinning. If the switch breaks, the washer will not run at all — it will not fill, agitate, or drain, even though the motor may hum.
Lid switches wear out because the lid presses on them thousands of times over several years. The plastic housing cracks, the metal contact inside corrodes, or the spring that holds the plunger loses tension. Once it fails, there is no repair — you replace the whole switch.
A broken lid switch is one of the most common Whirlpool washer failures and one of the easiest to fix yourself. The part costs between $25 and $60 depending on your model, and the job takes 15 to 30 minutes with basic tools.
Key Takeaways
- The lid switch sits under the lid or on the frame and must be replaced as a complete unit when it fails; it cannot be repaired.
- You will need your washer's model number to order the correct switch, which you can find on a sticker inside the lid or on the back of the machine.
- The job requires only a screwdriver and takes 15 to 30 minutes; you do not need to remove the entire lid or cabinet.
- After installation, test the switch by closing the lid and listening for the washer to hum or begin filling; if nothing happens, the new switch may be faulty or installed backward.
Finding your model number and ordering the right part
Whirlpool makes dozens of washer models, and the lid switch part number varies by model year and design. Ordering the wrong switch means wasting money and time. Start by locating your model number on the washer itself.
Open the lid and look for a white or silver sticker on the underside of the lid frame or on the inner wall of the tub. The sticker shows a model number that usually starts with "WTW" or "WFW" followed by numbers. Write this down. If you cannot find it on the lid, check the back of the washer near the power cord or on the side of the cabinet.
Once you have the model number, go to a parts supplier such as Whirlpool's official parts website, AppliancePartsPros, or PartSelect. Type in your model number and search for "lid switch." The site will show you the correct part number and price. Order it and wait for delivery — most suppliers ship within two to five business days.
Unplugging the washer and locating the old switch
Before you touch any part of the washer, unplug it from the wall outlet. This prevents electric shock and protects the machine. Wait a few seconds after unplugging to let any residual charge drain.
Next, locate the old switch. On most Whirlpool top-load washers, the switch sits under the lid, mounted to a bracket on the frame. Open the lid fully and look at the underside of the lid itself or at the top edge of the tub rim. You will see a small plastic box, usually black or white, with a metal plunger sticking out or a small arm that moves when the lid closes.
On some models, the switch is mounted on the side of the cabinet near the hinge. If you cannot find it by looking, check your washer's manual or search online for "[your model number] lid switch location." A photo from the manufacturer will show you exactly where it is.
Removing the old switch
The old switch is held in place by one or two screws and connected by a wire harness. Start by disconnecting the wires. Look at the back or side of the switch box — you will see a plastic connector with two or three wires plugged into it. Gently pull the connector straight out. Do not yank on the wires themselves; pull on the plastic connector body.
Now remove the screws. Use a Phillips or flathead screwdriver (depending on your model) to unscrew the bracket that holds the switch to the frame. Most switches have one screw on top and one on the side, or sometimes just one central screw. Keep the screws in a small cup or on a piece of tape so you do not lose them.
Once the screws are out, the switch will come free. Set it aside. You may see a small plunger or arm that was pressed by the lid — this is part of the old switch and will be replaced by the new one.
Installing the new switch
Take the new switch out of its packaging and compare it to the old one. They should look similar in size and shape. Check that the connector on the back has the same number of pins as the old one — usually two or three.
Position the new switch in the same location where the old one sat. Align the screw holes with the holes in the frame. Insert the screws by hand first to make sure they thread correctly, then tighten them with your screwdriver. Do not over-tighten — snug is enough. If you strip the hole, the switch will not stay in place.
Now reconnect the wire harness. Take the connector from the new switch and push it firmly into the socket where the old wires came from. You should hear or feel a small click. The connector should sit flush against the frame with no gap.
Testing the new switch before running a load
Plug the washer back into the wall outlet. Do not start a wash cycle yet. Instead, close the lid gently and listen. Within a second or two, you should hear the washer hum or begin to fill with water. This means the switch is working. Open the lid and the water should stop when ready.
If nothing happens when you close the lid, the switch may be installed backward or the connector may not be fully seated. Unplug the washer, open the lid, and check that the connector is pushed all the way in. If it is, unplug the washer again and flip the connector 180 degrees — some connectors can be inserted either way, and reversing it fixes the problem.
If the washer still does not respond, the new switch may be faulty. Contact the parts supplier and request a replacement under warranty. Do not run a full wash cycle until the switch responds to the lid closing.
Common mistakes and how to avoid them
The most common mistake is ordering the wrong part number. Always double-check your model number before ordering. If you are unsure, call the parts supplier with your model number and ask them to confirm the switch part number over the phone.
The second mistake is not fully seating the wire connector. If the connector is not pushed all the way in, the switch will not work even though it is installed correctly. Push it until you feel resistance and see that it is flush with the frame.
The third mistake is over-tightening the mounting screws. If you strip the plastic holes in the frame, the switch will rattle and may not make good contact with the lid. Tighten the screws until they are snug, then stop.
Finally, some people forget to unplug the washer before starting. Always unplug it first. Even though the lid switch itself carries low voltage, the washer's motor and pump are powered by household current, and touching the wrong part could cause injury.
Frequently Asked Questions
How do I know if my lid switch is actually broken?
If the washer does not start, fill, or spin no matter what buttons you press, and the lid closes normally without sticking, the switch is likely broken. You can test it by closing the lid and listening for the washer to hum or begin filling. If nothing happens, the switch is faulty. Some washers have a reset button or a thermal fuse that can also cause the same symptom, so if replacing the switch does not fix it, those parts may need checking too.
Can I use a switch from a different Whirlpool model?
Not reliably. While some switches may physically fit, the electrical connector and the way the switch mounts can differ between models. Using the wrong switch may cause the washer to malfunction or not start at all. Always order the part number that matches your exact model number.
What if the wire connector does not fit the new switch?
This usually means you ordered the wrong part. Check your model number again and verify the part number on the box matches what the supplier recommended. If the numbers match but the connector is different, contact the supplier — you may have received the wrong item and can request a return.
Do I need to drain the washer before replacing the switch?
No. The lid switch is mounted above the tub and does not touch water. You can replace it whether the tub is full or empty. However, if water is in the tub, do not open the lid during the replacement, as water may spill onto the floor.
How long does a new lid switch usually last?
A new OEM (original equipment manufacturer) switch typically lasts as long as the original — usually 5 to 10 years depending on how often you use the washer. Aftermarket switches may wear out sooner. The switch will eventually fail again, but this is normal wear and not a sign that something else is wrong with the washer.
