Results
Opens at 243°F (117°C)
Closed at 180°F (82°C) and open at
280°F (138°C)
Infinite resistance should be
measured in one direction and

direction.
NOTE: Ohmmeter must contain a
battery of 6 volts minimum.
Discharge Capacitor
Magnetron
Blower motor
Remove wires from capacitor
terminals and connect ohmmeter, set
on highest resistance scale to
terminals.
Between Terminals: Meter should
momentarily deflect towards zero
then return to over 5 MΩ. If no
deflection occurs, or if continuous
deflection occurs, replace capacitor.
Also check between each terminal and
capacitor case.
Discharge Capacitor
Terminal to Case: Infinite resistance
Remove wires from magnetron and
connect ohmmeter to terminals. Also
check between each terminal and
ground.
Each terminal to ground measures
Infinite resistance.
Note: This test is not conclusive. If
oven does not heat and all other
components test good replace the
magnetron and retest.
Between Terminals: Less than 1 Ω

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 bottom of 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 (20°C).
3. Place container on the center of the oven shelf and heat the water for 62 seconds.
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 complete.
5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the temperature rise.
6. See the Temperature Chart provided 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: 930  watts output using the traditional power test for model RCS10MP
+ 100  watts (1 magnetrons X 100 watts)
1030  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.
