Using this Westinghouse LT series lid switch and harness is quite simple. First, make sure your washing machine is unplugged from the power source to avoid any electrical hazards. Then, carefully remove the old lid switch and harness according to your machine's manual. Install the new switch and harness in the same place as the old ones, making sure all the connections are secure. When using the washing machine, if the lid is opened, the magnetic reed switch will detect it and stop the machine to protect you. If the machine goes out of balance during operation, the OOB microswitch will also work to keep things safe. As for maintenance, regularly check the wiring harness for any signs of wear or damage. If you notice any frayed wires or loose connections, replace the parts immediately. And always keep the switch clean to ensure smooth operation. If you have any questions or concerns, don't hesitate to contact us.
