Microwave Leakage Testing

!WARNING

To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor before servicing, unless testing requires power.

!WARNING

Check for radiation leakage after servicing. Should the leakage be more than 4 mW/cm2 inform Maytag immediately. After repairing or replacing any radiation safety device, keep a written record for future reference, as required by D.H.H.S. and HEW regulations. This requirement must be strictly observed. In addition, the leakage reading must be recorded on the service repair ticket while in the customer’s home.

Equipment

•Electromagnetic radiation monitor

•600 cc glass beaker or plastic power bowl

Procedure for Measuring Radiation Leakage

Note before measuring:

•Do not exceed meter full scale deflection. Leak monitor should initially be set to the highest scale.

•To prevent false readings the test probe should be held by the grip portion of the handle only.

•The scan speed is equal to one inch per antenna revolution or one inch per second if antenna speed is unknown.

•Areas to be checked are all door seal areas and any venting parts.

•Leakage with the outer panel removed ...4mW/cm2 or less.

•Leakage for fully assembled oven with door normally closed ...4 mW/cm2 or less.

•Leakage for a fully assembly oven (before the latch switch (primary) is interrupted) while pulling the door

... 4 mW/cm2 or less.

1.Pour 275 cc ±15 cc (9 oz ±1/2 oz) of 20°C ± 5°C (68°F ± 9°F) water in a beaker which is graduated to 600 cc and place the beaker in the center of oven.

2.Set the radiation monitor to 2450 MHz and use it following the manufacturer’s recommended test procedure to assure correct results.

3.While measuring the leakage, always use the two inch (5 cm) spacer supplied with the probe.

4.Press the start pad or turn on the timer and with the magnetron oscillating, measure the leakage by holding the probe perpendicular to the surface being measured.

Measurement with the Outer Panel Removed

!WARNING

Avoid contacting any high voltage components.

Whenever you replace the magnetron, measure for radiation leakage before the outer panel is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring around the magnetron.

Measurement with a Fully Assembled Oven

After all components including the outer panel are fully assembled, measure for radiation leakage around the door periphery, the door viewing window, the exhaust opening, and air inlet openings.

Record Keeping and Notification After Measurement

1.After any adjustment or repair to a microwave oven, a leakage reading must be taken. Record this leakage reading on the repair ticket even if it is zero.

2.A copy of the repair ticket and the microwave leakage reading should be kept by the repair facility.
