not bent, broken or deficient in their ability to hold the switches.
8.5. Avoid inserting nails, wire etc. through any holes in the unit
during operation.
Never insert a wire, nail or any other metal object through the lamp holes on the cavity or any
holes or gaps, because such objects may work as an antenna and cause microwave leakage.
8.6. Confirm after repair
1. After repair or replacement of parts, make sure that the screws of
the oven, etc. are neither loose nor missing. Microwaves might
leak if screws are not properly tightened.
2. Make sure that all electrical connections are tight before inserting
the plug into the wall outlet.
3. Check for microwave energy leakage. (Refer to procedure for
measuring microwave energy leakage).
