Troubleshooting
When one of the following situations occur, please unplug the unit and contact a Trane dealer
immediately:
•
There is harsh sound during operation
•
The terrible odors emitted during operation
•
Water is leaking in the room
•
•
•
There is an abnormal heat in power supply cord and power plug.
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.
