I understand you are experiencing difficulties with your Microwave. Microwaves contain high voltage internal components that can retain a lethal electrical charge even when the microwave is completely unplugged. Door repairs and adjustments, even minor ones, can cause microwave leakage and a microwave shielding leakage test must be performed using a survey meter after any microwave service. This repair should be done only by a qualified service technician. I have provided a link To Sears Home Services if you decide to schedule service. It may be cost effective to just replace the unit, I have also provided a link to the Microwave section of Sears.com to price out what a replacement would cost.
