4-4 Electrical Malfunction

Troubleshooting (Power)

Check terminal block voltage.

(220V~240V, 50/60Hz)

YES

No Power

Check the wiring.

Check the votage of PCB, SMPS

-input : 220V~240V

-output : 12V, 5V

Replace the defected PCB.

Check the terminal block connections

Check the circuit breaker.

Replace or Repair the wiring

Troubleshooting (Heating)

Check the relay terminal voltage

(220V~240V)

YES

Heating Failure

Check the wiring.

Check the all IGBT terminal resistance

(G-E, G-C, E-C)

Is there any shorted circuit?

Perform the 'PCB failure' process

Repair the relay or missing circuit

component.

Replace or Repair the wiring

Check Fuse at Filter PCB.

Normally, If IGBT is damaged

and shorted, Fuse will blow and

power off.

YES

1. Replace the Fuse at Filter PCB.

If not change Fuse, Repaired Inverter

PCB will damage again.

2. Replace the Inverter PCB.
