Question

I am trying to replace the handle assembly and am having great difficulty getting to the s***w at the very top and very bottom in the door that s***w into the handle. There are two screws on top and two on bottom of handle...I can access two through the holes in the door assembly. I have stareted to remove the outer plastic frame from the glass portion of the door but seems hard to remove. I have the top and bottom areas of the outermost plastic frame disconnected from the glass, but can't get the rest of the fram by the latch to separate from the inner frame. Not sure where to go from here.Thank you!
