Gree AC Refrigerant System Diagram

*problem

The unit will not deliver air

Reason / solution

Reason: There are many system functions that will stop the air flow.

Solution: Check for the following:

In heating mode, the indoor fan may not start for three minutes if the room temperature is too low. This is to prevent cold air from flowing.

And in heat mode, if the outdoor temperature is low and humidity is high, the system may need to defrost for 10 minutes before starting the heating cycle.

To dry mode, the indoor fan may stop for three minutes during the compressor shutdown delay.

 Otherwise, you should contact a qualified service professional for assistance.

*problem

Discharge air louvre or circulation of moisture at outlet vent.

Reason / solution

Reason: It is normal for the system to develop condensation or moisture on the discharge air louvers when the hot humid air is cooled for a long time.

Solution: Condensation or moisture will disappear as the system cools and the room space deteriorates.

*problem

System does not restart

Reason / solution

Reason: The system has an inherent three-minute delay to prevent short and / or rapid cycling of the compressor.

Solution: Wait three minutes for the security delay to expire.

*problem

Indoor unit emits unpleasant odor when started

Reason / solution

Cause: Usually unpleasant odors occur as a result of mold or mildew on coil surfaces or air filters.

Solution: Wash the indoor air filter in warm water with a mild cleaner. If odors continue, contact a qualified service professional to clean the coil surfaces.

*problem

You hear a “flowing water” sound

Reason / solution

Reason: It is common for systems to have “water flowing” or “greggling” equal to the refrigerant pressure when the compressor starts and stops.

Solution: After two or three minutes the noise should stop when the refrigerant system is equalized.

*problem

Thin fog or vapor released from the indoor unit when the system is running

Reason / solution

Reason: It is normal for the system to emit slight fog or water vapor when extremely humid cools the hot air.

Solution: The fog or water vapor will disappear as the system cools and dehumidizes the room space

*problem

System will not run

Reason / solution

Reason: There are several conditions that will prevent the system from running.

Solution: Check for the following:

The turned circuit breaker is “stuck” or “closed”.

 The power button of the remote is not on.

Remote controllers have fewer batteries.

The remote controller is in sleep mode or timer mode.

 Otherwise, contact a qualified service professional for assistance.
