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

All Amana and Menumaster microwave oven power outputs are rated using the IEC705 standards. Using the
IEC705 test method requires precision measurements and equipment that is not practical to be performed in the
field. Using the test shown below will indicate if the oven performance is satisfactory.
Test equipment required:
•
1000 ml test container and thermometer (Amana power test kit R0157397 Fahrenheit / Menumaster power
test kit M95D5 Celsius).
Important Notes:
•
Low line voltage will cause low temperature rise / power output.
•
Ovens must be on a dedicated circuit, properly grounded, and polarized. Other equipment on the same
circuit may cause a low temperature rise / power output.
•
This test and results are not a true IEC705 test procedures and are only intended to provide servicers with
an easy means of determining if the microwave oven cooking output is correct.
•
Oven must be cold, before performing this test.
Procedure
1. Fill the test container to the 1000 ml line with cool tap water.
NOTE:
Water temperature should be approximately 60° F / 16° C
2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1).
3. Place test container of water in the center of oven cavity using the lowest rack position and close door.
4. Heat the water for a 33-second full power cycle by using the microwave service test procedure.
a. Oven must be in STANDBY mode.
b. Close the door.
c. Press Hidden Pad, 1, 3, 5, 7, 9.
d. Press 3 to activate microwave service mode.
e. Open the door after 33 seconds have elapsed.
5. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record
temperature (T2).
6. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature
rise (
T).
7. If the temperature rise (
T) meets or exceeds the minimum, the test is complete. If the temperature rise (
T)
fails to meet the minimum temperature rise, test the line voltage to verify it is correct. Then repeat steps 1-6
making sure to change the water. If the temperature rise (
T) fails to meet the minimum temperature rise again,
the oven will require service.
