Power Test (Traditional 1 Liter Test) - Maytag RS511 Service Manual

Component Testing Procedures
To avoid risk of electrical shock, personal injury, or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
To insure proper functioning of the interlock system if the 12 Amp. line fuse has opened, the switch assembly must be
replaced along with the fuse.
For continued protection against radiation hazard, replace only with identical replacement components.
Precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy:
• Do not operate or allow the oven to be operated with the oven door open.
• Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and
make repairs as necessary: (1) Interlock operation, (2) Proper door closing, (3) Seal and sealing surface(s) (arcing, wear and
other damage), (4) Damage to or loosening of hinges and latches, (5) Evidence of dropping or abuse.
• Before turning or microwave power for any service test or inspection within the microwave generating compartments, check the
magnetron, wave guide, or transmission line, and cavity for proper alignment, integrity, and connections.
• Any failed or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems
shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.
• A microwave leakage check to verify compliance with the federal performance standard should be performed on each oven prior
to release to the owner.
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 63 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.
• The IEC-705 test method requires precision measurements and equipment. It is not practical to perform the IEC
NOTES:
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:
+ 100  watts (1 magnetrons X 100 watts)
• 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.
