WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power to microwave and discharge capacitors
before servicing, unless testing requires power.

Power Test (Traditional Test Method)
Test equipment required is Amana power test kit R0157397 (Fahrenheit), or
Menumaster power test kit M95D5 (Celsius).
1. Fill the plastic container to the 1000 ml. line with cool tap water.
2. Using the thermometer; stir the water, measure, and record the water temperature.
Initial water temperature should be approximately 60
°
F (16
°
C).
3. Place container on the center of the oven shelf and heat the water for
33 seconds for ovens with more than 1550 watts
or
63 seconds for ovens with less than 1550 watts
.
NOTE:
Use the second hand of a watch, not the oven timer.
4. Stir the water, measure and record the temperature of the water after heating time is complete.
5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the
temperature rise (
∆
T).
6. See the Traditional Power Test Temperature Chart below.
NOTES:
•
The IEC-705 test method requires precision measurements and equipment. It is not practical to perform
the IEC test in the field. To convert the traditional power test results to the approximate IEC-705 rating,
take the traditional power test results and add 100 watts per magnetron for the unit being tested.
Example:
850
⎯
watts output using the traditional power test
+ 100
⎯
watts (1 magnetron X 100 watts)
950
⎯
Approximate IEC-705 results
•
Always perform power test three times for accuracy, changing the water after each test is performed.
•
Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power
tests should be made if temperature rise appears marginal.
•
Low line voltage will cause lower temperature rise.
