MICROWAVE POWER TEST
Power Test
All ACP 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.
Procedure
Fill the test container to the 1000 ml line with cool tap water as close to 60° F / 16° C as possible.
Using the thermometer, stir water for ten seconds; measure, and record the temperature.
Place test container of water in the center of oven cavity and close door.
Heat the water for a 33-second full power cycle.
At end of the cycle, remove test container. Using the thermometer, stir water for ten seconds and
record temperature.
Subtract the starting water temperature from the ending water temperature to obtain the temperature
rise.
If the temperature rise meets or exceeds the nominal microwave energy rating found on the
model/serial tag, the test is complete. If the temperature rise 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 fails to meet the minimum temperature rise again the oven will require service.
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 procedure and are only intended to
provide servicers with an easy means of determining if the microwave oven cooking output is correct.
Set Up for Power Test
There are two methods to run microwave only:
1) Use Service Test Mode #3, the oven can be set up to run microwave only. The oven must be at
room temperature for best results
2)
Microwave only mode (oven must be below 212F / 100C)
