Troubleshooting

WARNING
Possible causes
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.
* The air conditioner itself has no bad smell. If any. It is the bad smell
accumulated from environment. Solution: Clean the air filter.
* If still any problem, the air conditioner shall be cleaned (Please
contact Authorized Trane dealer)
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.
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.
This is the sound caused by expansion of plastic panel or other parts
due to the change of temperature.
* 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)
