Product review (5 stars): Don't I feel dumb!
I had the lid-lock flashing light problem like some others. After some research, I purchased this replacement for my washer hoping it would solve the problem. Nope! After further research, it may be the actuator motor. Sure, I'll purchase that next. The washer wasn't even agitating or anything. The actuator comes in and I set to work.
  I then tilt the washer forward like you may see in the YouTube videos. Ready to replace the actuator on the underside, I find the BOLT on the pulley has come loose. Causing the main drive belt to slip off the pulley! Reattach the belt to the pulley and tighten the bolt. Washer running just fine!
  $30 for this lid switch (which is an exact replacement) + $30 for an actuator (which was an exact replacement also) and all I had to do was get a little dirty and tighten ONE bolt. Great going,  me!
