TGM AC 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 | |
| SILENCE function is activated(optional function) | SILENCE function can lower product performance by reducing operating frequency. Turn off SILENCE function | |
| 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 | |
| Remote control batteries are dead | Replace batteries | |
| 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 | |
| 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 exetremtly 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 |
NOTE: If your problem persists after performing the checks and diagnostics above, turn o your unit immediately and contact an authorized service center.
