Abstract

An improved door for microwave ovens having no exposed nut and bolt type means to retain the various components of such door together. The door is so constructed that the method for taking the door apart is not readily apparent to the average microwave oven user. Various components are mounted on the interior housing panel and various other components are mounted on the exterior housing panel. Then the interior housing panel and the exterior housing panel and their associated respective components are mounted together by concealed retaining means.
