How to Check a Capacitor

THE MICROWAVE SYSTEM

1.Disconnect the oven from the power source.

2.Fully discharge the capacitor.

3.Isolate the capacitor from the circuit.

4.Connect the ohmmeter between the capacitor terminals. The ohmmeter should momentarily indicate a low impedance and then slowly return to infinite resistance.

5.Reverse the ohmmeter leads and repeat Step 4.

6.Check each terminal to case. Infinite resistance (open) should be indicated.

How to Check a Magnetron for Open/Shorted Filament

1.Disconnect the AC power source and discharge the high-voltage capacitors.

2.Isolate the magnetron from the circuit by removing the wires from the F and FA terminals. Figure 25.

3.An ohmmeter connected between the filament terminals (F, FA) should indicate a reading of less than 1 ohm. Figure 25.

4.A continuity check between either filament terminal and the magnetron chassis should indi- cate an infinite resistance (open).

How to Check a High-Voltage or Filament Transformer

1.Disconnect the AC power source and discharge the high-voltage capacitors.

2.Disconnect all the wires in question going to the transformer.

3.Use an ohmmeter to check the impedance of the primary and secondary winding. Refer to the high-voltage and filament transformer table below to determine if the transformer is OK. If the resistance is different then the table indicates, replace the transformer.
