Hello: I have had that problem and have fixed it by replacing one of the 3 saftey Mico Switches on front door. I believe it is the top one that causes the 3 sec shutdown. Very easy to replace after turning off power, take cover off and without taking the door assembly apart the top switch can be replaced by lifting the little plastic retainer and pushing switch to the side before lifting out.
