Microwave Power Test

(TRADITIONAL TEST METHOD)
Test Equipment Needed:
• Amana power test kit R0157397 (Fahrenheit) or
• Menumaster power test kit M95D5 (Centigrade)
1. Fill the plastic container to the bottom of the 1000 ml.
lines with cool tap water.
2. Using the thermometer; Fahrenheit or Centigrade,
stir the water, measure and record the water
temperature. IMPORTANT: Initial water
temperature should be approximately 60°F (20°C).
3. Place the container on the center of the oven shelf
and heat the water for 63 seconds for ovens rated
less then 1550 watts or 33 seconds for ovens with
more then 1550 watts of power.
ONE MINUTE, THREE SECONDS run time chart for units less than 1550 watts cooking power.

NOTE: Use a watch second hand, not the oven timer.
4. Stir the water, measure and record the temperature
of the water after heating time is completed.
5. Subtract the starting water temperature (Step 2) from
the ending water temperature (Step 4) to obtain the
temperature rise.
6. Refer to the Temperature Chart.
NOTE: Variation or errors in the test procedure will
cause a variance in the temperature rise
indication. Additional power tests should be
made if temperature rise appears marginal.
NOTE: Low line voltage may cause lower power output
(temperature rise).
NOTE: Always perform 3 tests for accuracy. Change
water after each test
