Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection MECH-04 Error Fix: Oven Door Not Closing Properly

Error code MECH-04 on the Jenn-Air JMW2430IM 30 in Combination Microwave Wall Oven with True Convection means: Oven Door Not Closing Properly. The oven door does not close flush against the oven frame, allowing heat to escape — causes include: worn or broken door hinges, bent hinge arms from forcing the door past its stop position, loose hinge mounting screws, or a warped door; open the door to the broil stop position (partially open) and check the hinge clips/locks; if the hinges have hinge locks, they must be in the unlocked position for the door to close fully; replace hinges if worn; on Jenn-Air Pro-Style ranges, the heavy commercial-weight door requires robust hinges that wear faster than standard hinges
