Gree GWH09AB-A3DNA1B air conditioner troubleshooting
|Air conditioner does not restart.||Cause: The evo system has a built in 3 minute delay to prevent short and/or rapid cycling of the compressor.|
|Solution: Wait 3 minutes for the protection delay to expire.|
|Air conditioner emits unpleasant odor when started.||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.|
|You hear a “water fl owing” sound.||Cause: It is normal for the air conditioning 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 2 or 3 minutes.|
|A thin fog or vapor coming out of the unit when air conditioner is running.||Cause: It is normal for the air conditioning 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.|
|You hear a slight cracking sound when the air conditioner stops or starts.||Cause: It is normal for the air conditioning system to make "slight cracking” sounds from parts expanding and contracting during system starts and stops.|
|Solution: The noises should discontinue as temperatures equalizes after 2 or 3 minutes.|
|The unit will not run||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 control are low.
• Remote control is in Sleep mode or Timer mode.
• Otherwise, you should contact a Qualified Service Professional for assistance.
|Heating or cooling not running effi ciently.||Cause: Your evo system is designed to operate at peak efficiency for years with routine maintenance.|
|Solution: Check the following reasons for loss of system efficiency:
• Remove obstructions blocking the return or discharge air flow into the room.
• Clean dirty or blocked indoor air filter that is restricting air flow 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.
|Wireless remote control lost or does not work.||Cause: There are a number of reasons for the remote control not to work.|
|Solution: Check the following reasons for the remote control not working:
• The batteries might be low, change the batteries.
• The remote control must be within 25 ft (7.6m) with no obstructions of the indoor unit.
If remote control is lost or damaged and need to be replaced, contract your qualified service professional for assists. In the meantime, use the manual Override Mode to operate the evo system.
|Water leaking from indoor unit into the room||Cause: It is normal for air conditioning system generate condensate water in cooling mode. The evo system is designed to effectively and efficiently collect and safely drain the condensate water from the indoor unit to the outdoors via a condensate drain tube.|
|Solution: Water leaking into the room indicates:
• The indoor unit is not level right to left. Level indoor unit.
• The condensate drain tube is restricted or plugged. All restricts must be removed to allow continuous gravity force drainage.
• If problem persist, contact a qualified service professional for assistance.
|Water leakage in outdoor unit||Cause: It is normal for outdoor unit to generate condensate water in reverse cycle heating mode and defrost.|
|Solution: Water leaking from the outdoor unit is normal in reverse cycle heating mode or defrost.|
