I took my washer apart and a pin came off I don't know where it goes.
Answer Hello Jose. It may be the shipping pin that are in the small plastic cups under the unit. If so, it is not needed.
Is the 3949247 lid switch compatible with my LSR8233EQ0 Washing Machine?
Answer Hello Elaina. 3949247 is the correct lid switch for the model number you provided.
Washer filled but will not start with lid down or up.
Answer Hello Pamala. You will need to check and see if the lid switch is bad and will need to be replaced on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
