Door Disassembly - Frigidaire CGMV173KB Servicing

NOTE
After any service to the door:
1. Make sure that door sensing switch and secondary
interlock switch are operating properly. (Refer to
section 3 "Test Procedures".).
2. An approved microwave survey meter should be
used to assure compliance with proper microwave
radiation emission limitation standards.
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.
4. Re-install outer case and check for microwave
leakage around door with an approved microwave
survey meter. (Refer to Microwave Measurement
Procedure.)
NOTE
The door on a microwave oven is designed to act as an
electronic seal preventing leakage of microwave energy
from oven cavity during cook cycle. This function
does not require that door be air-tight, moisture-tight
or light-tight. Therefore, occasional appearance of
moisture, light or sensing of gentle warm air movement
around oven door is not abnormal and does not indi-
cate a leakage of microwave energy from oven cavity.
