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.
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

Note: This test is not conclusive. If
oven does not heat and all other

All 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
•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 procedures 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.
