My spacemaker's GE Profile manufactured in 2002 , handle broke off

It broke in such a way a replacement handle can’t be used. Is there any way I can find another door to replace it? Parts are not available from GE and the part for a new door is WB55x 10427. Is there any where where microwave parts from old GE’s could be found?
