Product review (5 stars): works perfect
the only thing you need to be awared is this part is actually for secondary switch(top switch), not primary switch(bottom switch). if you need primary switch, you can use the original secondary switch from the microwave as primary and use this switch as secondary. the reason is the hole on the switch is a little bit smaller then the stick-out holder on the microwave for the primary switch. it does not fit all the way in but has no problem as secondary switch on the top.  hope this will help. other than this, it is a really good product, and save a lot money for repair.
