Trouble-Shooting
Do not repair the air conditioner at your discretion. Incorrect repair may cause electric shock or
fire, so please contact SINCLAIR Authorized Service Center for professional repair.
Following checks prior to contact may save your time and costs.
Fault Cause Analysis
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 SINCLAIR Authorized
Service Center).
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 “hua-hua” or “di-du-di-du” noise. This is the
flowing sound of refrigerant other than fault.
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 of friction caused by expansion of
panel or other parts due to the change of
temperature.
