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 door sensing switch and primary interlock switch |

After any servicing, make sure of the following :
1.Door latch heads smoothly catch latch hook through latch holes and that latch head goes through center of latch hole.
2.Deviation of door alignment from horizontal line of cavity face plate is to be less than 1.0mm.
3.Door is positioned with its face pressed toward cavity face plate.
