In and out play of the door allowed by the upper and lower position of the latch hook should be less than 0.5mm. The vertical position of the latch hook should be adjusted so that the secondary interlock switch and primary interlock switch are activated with the door closed. The horizontal position of the latch hook should be adjusted so that the monitor switch and stop switch are activated with the door closed. 8. Secure the screws with washers firmly. 9. Check all of the switches operation. If any switch has not activated with the door closed, loosen screw and adjust the latch hook position. After adjustment, check the following. 1. In and out play of door remains less than 0.5mm when in the latched position. First check upper position of latch hook, pushing and pulling upper portion of door toward the oven face.Then check lower portion of the latch hook, pushing and pulling lower portion of the door toward the oven face. Both results (play in the door) should be less than 0.5mm. 2. The secondary interlock switch and primary interlock switch interrupt the circuit before the door can be opened. 3.
