PRiMARY iNTERLOCK SYSTEM TEST
1. Disconnect the power supply cord, and then remove the outer case and the back plate assembly.
2. Open the door and block it open.
3. Wait for 60 seconds to discharge the high voltage capacitors of the inverter unit.
4. Disconnect the high voltage wire from the magnetron terminal with insulated pliers.
5. Make the terminal (metal part) of the high voltage wire contact to the magnetron body with insulated pliers.
6. Now, the capacitors of the inverter unit are discharged.
7. Reconnect the high voltage wire to the magnetron terminal after discharging.
WARNiNG: Use the pliers that the portions of their handles are insulated completely to avoid an electric shock.
8. Connect the ohmmeter to the white/white terminal of the noise filter and the white terminal of the convection motor. By
doing so, the state of the relay contacts using a ohmmeter can be checked. The meter should indicate an open circuit.
Because the relay contacts should be open.
If the relay contacts are closed, replace the circuit board entirely or the relay itself.
9. Reconnect all leads removed from components during testing.
10.Reinstall the outer case and the back plate assembly.
11. Reconnect the power supply cord after the outer case and the back plate assembly are installed.
12.Run the oven and check all function.
