Troubleshooting 18,000 & 24,000 Units

Overcurrent Protection

Overcurrent Protection

Status:

During cooling & dehumidifying, indoor unit

operates while other functions stop; During

heating operation, complete unit stops

1. Supply voltage is unstable

2. Supply voltage is too low

3. Coils are dirty

4. Improper refrigerant charge

Fault & Status

Possible Causes

Start Troubleshooting

Check if compressor’s connection

line is properly connected

Yes

Check if current value is higher than

the protectors setting

Adjust compressor’s

connection line

Replace overcurrent protector

Yes

Is units high pressure normal

Refer to high pressure

protection error

Yes

Check if unit voltage is normal

Check connections, contact

electric utility company

Yes

Replace main board
