Resetting a Gree outdoor unit can be a straightforward process, but it’s essential to understand the underlying reasons and the necessary steps to ensure a successful reset. This comprehensive guide will walk you through the entire process, providing detailed technical information and expert-level insights to help you diagnose and resolve any issues with your Gree outdoor unit.
Powering Down the AC
- Locate the Circuit Breaker: Identify the circuit breaker in your electrical panel that supplies power to your Gree outdoor unit. This is typically a dedicated breaker labeled for your air conditioning system.
- Flip the Breaker: Firmly switch the circuit breaker to the “Off” position, cutting power to the outdoor unit.
- Disconnect the Power Switch: Locate the outdoor power switch, usually mounted on the wall near the outdoor unit, and switch it to the “Off” position.
- Verify Power Disconnection: Ensure that the outdoor unit is completely powered down by checking that all indicator lights or displays are turned off.

- Identify the Reset Button Location: The reset button on a Gree outdoor unit is typically small and red, situated either on the unit itself or in close proximity. Consult your owner’s manual or the unit’s service label to determine the exact location.
- Accessibility Considerations: Ensure that you have easy access to the reset button, as you’ll need to press and hold it during the reset process. If the button is located in a tight or hard-to-reach area, consider using a small tool or implement to assist with the reset.
- Familiarize Yourself with the Button: Take a close look at the reset button, noting its size, color, and any surrounding markings or indicators. This will help you quickly identify and access the button during the reset procedure.
Resetting the Unit
- Press and Hold the Reset Button: Using your finger or a small tool, firmly press and hold the reset button for 3 to 5 seconds.
- Monitor the Indicator Lights: During the reset process, observe the unit’s indicator lights or display. You may notice the lights blinking or the display cycling through various codes, indicating that the reset is in progress.
- Release the Button: After holding the reset button for the recommended duration, release it. This should initiate the reset sequence within the Gree outdoor unit.
- Observe the Unit’s Behavior: After the reset, monitor the outdoor unit for any changes in its behavior or operation. You may notice the unit cycling through its startup sequence, with the compressor and fans activating.
Restoring Power to the AC
- Flip the Circuit Breaker: Return to the electrical panel and firmly switch the circuit breaker that supplies power to the Gree outdoor unit back to the “On” position.
- Turn On the Outdoor Power Switch: Locate the outdoor power switch and switch it to the “On” position, restoring power to the unit.
- Verify Power Restoration: Ensure that the outdoor unit is receiving power by checking for any indicator lights or displays that should be illuminated.
- Test the AC System: Once power is restored, try operating your air conditioning system to ensure that the reset was successful and the unit is functioning correctly.
Troubleshooting and Additional Considerations
If the reset process does not resolve the issue with your Gree outdoor unit, there may be other underlying problems that require further investigation. Some common causes for a reset may include:
- Protection Circuit Breaker Activation: The outdoor unit’s internal protection circuit breaker may have tripped, triggering the need for a reset.
- Thermostat Errors: Issues with the communication between the indoor and outdoor units, often caused by thermostat malfunctions, can necessitate a reset.
- Refrigerant Leaks: A refrigerant leak in the system can lead to various problems, including the need for a reset.
In such cases, it’s recommended to consult the Gree service manual or contact a professional HVAC technician for further troubleshooting and repair.
Remember, safety should always be your top priority when working with electrical systems. If you’re not comfortable performing the reset procedure or have any doubts about your ability to do so, it’s best to seek the assistance of a qualified HVAC professional.
