TROUBLESHOOTING

SAFETY PRECAUTIONS

If any of the following conditions occurs, turn off your unit immediately!

  • You smell a burning odor
  • The unit emits loud or abnormal sounds

Common Issues

The following problems are not a malfunction and in most situations will not require repairs.

Issue Possible Causes

Unit does not turn on when pressing ON/OFF button

| The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/ Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s anti-cold wind is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor temperature is too cold and the unit’s anti-freeze protection is activated in order to defrost the unit.

The unit changes from COOL/HEAT mode to FAN mode

| The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again.
The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again.
The indoor unit emits white mist| In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
Both the indoor and outdoor units emit white mist| When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.

The indoor unit makes noises

| A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.

Both the indoor unit and outdoor unit make noises

| Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises.
Issue                           Possible Causes

The outdoor unit makes noises| The unit will make different sounds based on its current operating mode.
Dust is emitted from either the indoor or outdoor unit| The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.

The unit emits a bad odor

| The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the outdoor unit does not operate|

During operation, the fan speed is controlled to optimize product operation.

Troubleshooting

When troubles occur, please check the following points before contacting a repair company.

Problem Possible Causes Solution

Poor Cooling Performance

| Temperature setting may be higher than ambient room temperature| Lower the temperature setting
The heat exchanger on the indoor or outdoor unit is dirty| Clean the affected heat exchanger

The air filter is dirty

| Remove the filter and clean it according to instructions
The air inlet or outlet of either unit is blocked| Turn the unit off, remove the obstruction and turn it back on
Doors and windows are open| Make sure that all doors and windows are closed while operating the unit
Excessive heat is generated by sunlight| Close windows and curtains during periods of high heat or bright sunshine
Too many sources of heat in the room (people, computers, electronics, etc.)|

Reduce amount of heat sources

Low refrigerant due to leak or long-term use| Check for leaks, re-seal if necessary and top off refrigerant
Problem                    Possible Causes                  Solution

The unit is not working

| Power failure| Wait for the power to be restored
The power is turned off| Turn on the power
The fuse is burned out| Replace the fuse
The Unit’s 3-minute protection has been activated| Wait three minutes after restarting the unit
Timer is activated| Turn timer off

The unit starts and stops frequently

| There’s too much or too little refrigerant in the system| Check for leaks and recharge the system with refrigerant.
Incompressible gas or moisture has entered the system.| Evacuate and recharge the system with refrigerant

System circuit is blocked

| Determine which circuit is blocked and replace the malfunctioning piece of equipment
The compressor is broken| Replace the compressor
The voltage is too high or too low| Install a manostat to regulate the voltage

Poor heating performance

| The outdoor temperature is extremely low| Use auxiliary heating device
Cold air is entering through doors and windows| Make sure that all doors and windows are closed during use
Low refrigerant due to leak or long-term use| Check for leaks, re-seal if necessary and top off refrigerant
