A steady 9 MΩ indicates an open capacitor. Steady continuity indicates a shorted capacitor. In either case, replace capacitor. Infinite Ω. Infinite resistance should be measured in one direction and several hundred KΩ in the opposite direction. NOTE: Ohmmeter must contain a battery of 6 volts minimum.

Power Test (Traditional Test Method) Test equipment required is Amana power test kit R057397 (Fahrenheit), or Menumaster power test kit M95D5 (Celsius).. Fill the plastic container to the 000 ml. line with cool tap water.. Using the thermometer; stir the water, measure, and record the water temperature. Initial water temperature should be approximately 60 F (6 C). 3. Place container on the center of the oven shelf and heat the water for 33 seconds for ovens with more than 550 watts or 63 seconds for ovens with less than 550 watts. 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 ), from the ending water temperature (Step 4) to obtain the temperature rise ( T). 6. See the Traditional Power Test Temperature Chart 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 00 watts per magnetron for the unit being tested. Example: 850 watts output using the traditional power test + 00 watts ( magnetron X 00 watts) 950 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.
