FAQs

My washing machine won't start, but I think the lid switch is the problem. How can I test if it's actually faulty before buying a replacement?
You can test the lid switch using a multimeter. Disconnect the wires from the switch. Set your multimeter to continuity mode. Touch the probes to the switch terminals. If the multimeter beeps, the switch is likely closed and working. If it doesn't beep, the switch may be faulty. Refer to your washing machine's manual for the specific location of the lid switch wires.
Is replacing a washing machine lid switch difficult? Do I need special tools?
Replacing a washing machine lid switch is generally a straightforward task. You'll likely only need a screwdriver (usually a Phillips head) to remove the screws securing the switch and possibly a pair of pliers to disconnect wires. However, always refer to your washing machine’s service manual for specific instructions and tool recommendations as this can vary by model.
