WARNING
PROBLEM
System does not restart.
Indoor unit emits unpleasant
odor when started.
You hear a “water flowing”
sound.
A thin fog or vapor coming
out of the indoor unit when
system is running.
You hear a slight cracking
sound when the system
stops or starts.
The system will not run.
Heating or cooling
not running efficiently.
CAUSE/SOLUTION
Cause: The system has a built-in three-minute delay to prevent short and/or rapid cycling
of the compressor.
Solution: Wait three minutes for the protection delay to expire.
Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil
surfaces or air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist, contact
a qualified service professional to clean the coil surfaces.
Cause: It is normal for the system to make “water flowing” or “gurgling” sounds from
refrigerant pressures equalizing when the compressor starts and stops.
Solution: The noises should discontinue as the refrigerant system equalizes after two or
three minutes.
Cause: It is normal for the system to emit a slight fog or water vapor when cooling
extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and
dehumidifies the room space.
Cause: It is normal for the system to make “slight cracking” sounds from parts expanding
and contracting during system starts and stops.
Solution: The noises should discontinue as temperature equalizes after two or three minutes.
Cause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit breaker is “tripped” or “turned off.”
• Power button of remote is not turned on.
• Batteries in the remote controller are low.
• Remote controller is in sleep mode or timer mode.
• Otherwise, you should contact a qualified service professional for assistance.
Cause: With routine maintenance, your system is designed for years of peak efficiency.
Solution: Check the following:
• Remove obstructions blocking airflow into the room.
• Clean dirty or blocked indoor air filter that is restricting airflow into the system.
• Seal outdoor air leaks in the room space from door or windows.
• Relocate (if possible) other heating sources in the room space.
