Trane air conditioner troubleshooting

ProblemsPossible 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 louverIf the unit is running for extended periods of time in high humidity
conditions, moisture may accumulate on the guide louver
