formed prior to servicing if the oven is operative.
B. Do not operate or allow the oven to be operated
with the door open.
C. If the oven operates with the door open:
I ) Instruct the user not to operate the oven and
2) contact the manufacturer and the Center for
Devices and Radiological Health immediately.
D. Make the following safety checks on all ovens to
be serviced before activating the magnetron or
other microwave source, and make repairs as
necessary
1. Interlock operation
2. Proper door closing
3. Seal and sealing surfaces (arcing, wear, and
other damage)
4. Damage to or loosening of hinges and latches
5. Evidence of dropping or abuse

ance with the federal performance standard
should be performed on each oven prior to
release to the owner.
MICROWAVE LEAKAGE TEST
I . Place 275 ml. water in 600 ml. beaker
(WB64X5010).
2. Place beaker in center of oven shelf.
3. Set meter to 2450 MHz scale.
4. Turn oven "ON" for 5 minute test.
5. Hold probe perpendicular to surface being tested
and scan surfaces at rate of one inch/second. Test
following areas:
•
Entire perimeter of door and control panel
•
Viewing surface of door window
•
Exhaust vents
6. Maximum leakage 4MW/CM
7. Record date on service invoice and microwave
leakage report.
NOTE: MAXIMUM ALLOWABLE LEAKAGE
2
IS 5MW/CM . 4MW/CM
LOW FOR MEASUREMENT AND METER
ACCURACY.
Inform the manufacturer of any oven found to have
