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 (ACP Power Test Bpwl part # 12018801).

Digital watch / watch with a second hand for use on ovens with electromechanical timers.

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 co

rrect.

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 and close door.

5. Heat the water for a 33-second full power cycle.

NOTE: Use a digital watch or a watch with a second hand for ovens with electromechanical timers.

6. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record

temperature (T2).

7. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature

rise ( T).

8. 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.
