Product review (4 stars): Washing machine lid switch
This switch going bad is the reason why in so many cases your washer won't run. It is not an item a little old lady with a screw driver will be able to install. However if you have some mechanical abilities and follow the instructions that can be found on the net it is not that difficult.  I called my local appliance store for the switch they quoted me ($27.50). I think the price from Amazon was less than $15.00 and included shipping.
