1. Checklist :
1) Is the input voltage of outdoor terminal block is normal?
2) Is the reactor wire connected?
3) Is the DC_link capacitor("A") assembled in accordance the specification? (Outdoor PBA)
4) Is the DC_link resistor("B") value is normal? (Outdoor PBA)
2. Troubleshooting procedure
Is the connected of reactor wire?
Restart after power off.
Start the operation (cooling mode or heating mode)
voltage ("A") is normal in operation mode?
Normal range(280Vdc~320Vdc)
sensing voltage("B") is normal in operation mode?
Normal range (0.2Vdc~4.8Vdc)
Is the reactor insulation damaged?
Exchange the Reactor
