Symptom | Remedy |
---|---|
Indoor unit does not give cool air immediately when unit starts. | Compressor restarts after approximately three minutes to protect itself. On compressor restarting units starts to give cool air again. |
Unusual odor blowing from outlet when unit is started. | Open the door or window for 2 minutes and run the AC in Fan mode to allow fresh air inside the room. This helps to remove odors from inside the room. |
Sound of water ow during operation. | This is caused by refrigerant owing inside the unit |
Formation of mist while cooling | Room air is cooled quickly by cold air ow which looks like fog |
Creaking noise during start or stop | Deformation of plastic because of temperature change. |
Unit does not operate | Check electrical system connections, cords and fuses. Check if power supply is within 10% of rated supply. |
Decreased cooling eciency | Check 'set temperature' . Check for obstructions in air inlet and outlet. Check air lters for dirt. Check indoor fan speed. Check any other openings in the room |
Remote control does not work correctly | Check e ective distance to indoor unit. Check low battery error indication on remote display. |
Problems | Possible causes |
---|---|
Air conditioner does not run upon immediately restart after a stop. | To protect the air conditioner upon immediate restart after a stop, the microcomputer controller will delay the unit for 3 minutes before the air conditioner will run. |
Air conditioner blows out bad smell when it is initially started | The air conditioner itself has no bad smell Solution: Clean the air filter * If the problem persists after cleaning the filters, the air conditioner should be cleaned and serviced by an Authorized Trane dealer) |
You may hear 'Water Flowing' noise when the air conditioner is running | When the air conditioner is started, or the compressor is started or stopped during running or the air conditioner is stopped, sometimes you may hear the flowing sound of refrigerant. |
Sometimes a thin fog will flow out of the outlet when air conditioner is running under cooling mode. | This might occur when indoor temperature and humidity are high. This is because the indoor air is quickly cooled down. After a period of time, the fog will disappear with the decrease of indoor temperature and humidity. |
You may hear a slight crack when the air conditioner is started or stopped | This is the sound caused by expansion of plastic panel or other parts due to the change of temperature |
The unit can not run | * Has the power been shut down? * Does power plug come loose from the socket? * Is the circuit protection device tripped off or not? * Is voltage higher or lower? (Tested by professionals) * Is the Timer correctly used? |
Cooling(Heating) efficiency is not good | * Is Temp. setting suitable? * Were inlet and outlet vents obstructed? * Is there too much dust accumulated and obstructed the filter? * Are the windows and doors closed? * Did Fan speed set at low speed? * Is there any heat sources in the room? |
Wireless remote control is not functioning | * Is it in its receiving range? Or obstructed? * Check and/or replace the batteries. * The wireless remote control is damaged |
Water leakage in the room | * The air humidity is on the high side * Water overflowing due to blocked drain tube. Call your Authorized Trane dealer. * The connection position of indoor unit drainage pipe is loose. |
Water leakage in outdoor unit | * When the unit is running in the COOL mode, moisture from the indoor space will be discharged from the drain pipe. * When the unit is running in the HEAT mode, moisture may drip from the outdoor coil. * When the unit is running in Auto Defrost mode, frost that has formed on the outdoor coil will be thawed |
Noise is emitted from the indoor unit | * The sound of the fan or compressor relay switching on or off. * When the defrost mode is starting or stopping, the sound of refrigerant flow changing direction may be heard |
No air is being delivered from the indoor unit | * In the HEAT mode, if the temperature of the indoor coil is very low, the fan will stop for up to 3 minutes to prevent the delivery of cold air. * In the HEAT mode, frost may accumulate on the outdoor coil due to low outdoor temperature and/or high outdoor humidity. The unit will automatically switch to defrost mode, and the indoor unit will stop blowing air for approximately 8-10 minutes. During the defrost cycle, moisture may flow from the outdoor unit and steam may be observed. * In the dehumidifying mode, the indoor fan occasionally stops to avoid condensing water to be re-vaporized. |
Moisture on the guide louver | If the unit is running for extended periods of time in high humidity conditions, moisture may accumulate on the guide louver |
