Troubleshooting
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.
