Component Testing Procedures
Illustration Component Testing Results
Thermal cutout Disconnect all wires from TCO.
Measure resistance across terminals.
Cavity TCO............................................
Magnetron TCO.....................................
Closed at 32°F (0°C) and
Opens at 230°F (110°C)
Closed at 140°F (60°C) and
Opens at 320°F (160°C)
Diode Discharge Capacitor
Remove diode lead from capacitor and
connect ohmmeter.
Reverse leads for second test.
Infinite resistance should be
measured in one direction and 50KΩ
or more in the opposite direction.
NOTE: Ohmmeter must contain a
battery of 6 volts minimum.
Circuit Protector Discharge Capacitor
Remove circuit protector leads from
capacitor and connect ohmmeter.
Reverse leads for second test.
Infinite resistance should be
measured in one direction and 50KΩ
or more in the opposite direction.
NOTE: Ohmmeter must contain a
battery of 6 volts minimum.
Capacitor Discharge Capacitor
Remove wires from capacitor terminals
and connect ohmmeter, set on highest
resistance scale to terminals.
Also check between each terminal and
capacitor case.
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.
Terminal to Case: Infinite resistance
Magnetron Discharge Capacitor
Remove wires from magnetron and
connect ohmmeter to terminals. Also
check between each terminal and
ground.
Between Terminals: Less than 1 Ω
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.
Blower motor Remove all wires from motor.
Measure resistance across coil ............. Approximately 72 – 82 Ω
Stirrer motor Remove all wires from motor.
Measure resistance across terminals .... Approximately 12.8 – 13.5 KΩ
Filament

Transformer Discharge Capacitor
Remove all wires from terminals.
Measure resistance from:
Primary ................................................
Filament...............................................
Secondary to Ground screw on
transformer stack .................................
Less than <3 Ω
Less than <1 Ω
Approximately 110 – 125 Ω
Noise filter board Power In terminals.................................
Power Out terminals..............................
230 / 240 VAC
230 / 240 VAC
If no power in, check power outlet.
If no power out, check fuses
Component Testing Procedures
! WARNING
To avoid risk of electrical shock, personal injury or death, disconnect power to oven and discharge capacitor
before servicing, unless testing requires it.
All Amana and Menumaster 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 (Amana power test kit R0157397 Fahrenheit / Menumaster power
test kit M95D5 Celsius).
• Digital watch / watch with a second hand for use on ovens with electromechanical timers.
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.
Procedure
1. Fill the test container to the 1000 ml line with cool tap water.
NOTE: Water temperature should be approximately 60°F / 16°C
2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1).
3. Place test container of water in the center of oven cavity and close door.
4. Heat the water for a 33-second full power cycle.
NOTE: Use a digital watch or a watch with a second hand for ovens with electromechanical timers.
5. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record
temperature (T2).
6. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature
rise (∆T).
7. If the temperature rise (∆T) meets or exceeds the minimum, the test is complete. If the temperature rise (∆T)
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 (∆T) fails to meet the minimum temperature rise again
the oven will require service.
