Maytag 1800 W - 2005 Manual De Usuario

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

Check for radiation leakage after servicing. Should the 
leakage be more than 4 mW/cm

2

 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. 

•  Electromagnetic radiation monitor  
•  600 cc glass beaker or plastic power bowl 

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/cm

2

 or 

less. 

•  Leakage for fully assembled oven with door normally 

closed ...4 mW/cm

2

 or less. 

•  Leakage for a fully assembly oven (before the latch 

switch (primary) is interrupted) while pulling the door  
... 4 mW/cm

2

 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. 

 

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. 

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. 

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.
