Item
Resistance value
Attention: In test of the magnetron, confirm that the gasket is in good condition
and installed well.
Test of the high-voltage capacitor
D.
Under normal condition: 1. The resistance value of the two terminals shall be several
E. Test of the high-voltage diode
Measure with RX1000 range. The conduction resistance value shall be several ohm.
No matter which step is used in the measurement, the result shall be infinite.
F. Measurement of the fan motor
The resistance value of the two terminals shall be 200~300ohm
G. Measurement of the rotary tray motor
Position
Two ends of the heater
