How To Reset Gree Air Conditioner

Reset Gree Air Conditioner

Your Gree air conditioner is an electronic device with circuit boards, so it’s normal to encounter an error once in a blue moon.

If your air conditioner unit encounters an error, resetting it will correct it. But resetting a Gree air conditioner unit is complicated. So how do you reset a Gree air conditioner unit?


Resetting a Gree air conditioner depends on the design of your unit. Based on different models, you can reset the AC unit by:

  • Resetting using the remote.
  • Resetting it using the reset button on the unit.
  • Pressing the rest button on the thermostat.
  • Switching off the isolator switch.
  • Switching off the circuit breaker.

In the event of a power outage, the protection circuit breaker in your unit kicks in, which is in place to prevent fire and explosion.

In such a case, the AC unit may refuse to turn on after a period or blow hot air even when the thermostat is set to the lowest possible temperature.

This article explains the different methods to reset a Gree air conditioner unit. Read on.

5 Ways To Reset a Gree Air Conditioner

Reset Gree Air Conditioner

Resetting your Gree air conditioner unit can resolve several issues you may be facing. So, save yourself the cost of hiring a professional by resetting the unit first.

If, after resetting the air conditioner unit, the problem persists, then you will need a professional to come to inspect and diagnose the issue with your Gree air conditioner.

But before then, here are five methods you can use to reset a Gree air conditioner unit:

Method #1: Resetting It Using the Remote

Resetting It Using The Remote

Over the years, AC controllers have grown more advanced, technical, and complex. With new technology incorporated into the remote, today its importance cannot be overemphasized enough.

The AC remote gives you control of the AC compressor, choose from a wide selection of modes, economize on energy, set a timer, control fan speed, and even rest the unit, amongst others.

Here’s how to reset a Gree AC by using its remote:

  • On your remote, find the reset button.
  • Press and hold the reset button for 7 – 10 seconds or until the indoor unit gives a beep sound or buzzer.
  • Alternatively, you may not have a reset button, but a keyhole is often at the back of the remote with “Reset” written.
  • Use a toothpick or a pin to press and hold the reset button for 7 to 10 seconds or until you hear a beep sound.

Method #2: Resetting It Using the Reset Button on the Unit

Reset Button On The Unit

Depending on the model of the Gree AC unit you have, it may or may not have a reset button. But the ones that feature a reset button come in handy when the unit fails, especially when the compressor does not engage the electrical system.

In most models, the reset switch is located on the compressor in the outside unit. But some units have the reset button on the indoor unit. If you are having trouble locating the reset button on the unit, refer to the user manual.

Here’s how to reset a Gree AC using the reset button on the unit:

  • First, locate the reset button on the compressor or the indoor unit.
  • Next, press and hold the reset button for 7 seconds or until the unit powers down.
  • Next, unplug the AC unit from a power source, and let it sit for 5 to 10 minutes with no electricity flower through it.
  • After the time has elapsed, reconnect the AC to a power outlet and turn it back on.

Method #3: Resetting It Using the Thermostat

Resetting Using Thermostat

If you have a large AC unit, say a duct central Gree AC unit, you will likely have a smart central thermostat installed somewhere on the interior to regulate its temperature. The thermostat signals to cool the air depending on the temperature you set.

Sometimes, if the thermostat is malfunctioning, it could be because of a low battery. So, before you use that reset button, try to replace the battery. Removing the battery might be all the thermostat needs to reset the Gree AC unit.

Here’s how to reset a Gree AC by using the thermostat:

  • But first, find and unscrew the fasteners holding the front panel of the thermostat.
  • If your thermostat doesn’t use screws, find a handle, form of grip, or button on the front panel and then pry it out.
  • Remove the batteries and replace them with new ones.
  • Close the thermostat and try the AC.
  • If the issue persists, hold the power button for 7 to 10 seconds or until the unit restart.
  • When the unit reboots, check if it fixes the problem.

Method #4: Resetting It From the Isolator Switch

Resetting Using Isolator Switch

If none of the above resetting options fixes the problem, then it might be time to try resetting the AC from the isolator switch.

This switch sits between the AC and the main electrical supply. Its purpose is to isolate the AC unit from the electrical system, enhancing its safety during repairs and maintenance.

While the isolator switch is similar to the circuit breaker, they differ. The isolator is often near the outdoor unit rather than the switch box. An isolator switch is not a requirement for ACs, in case you don’t have one in your unit.

Here’s how to reset a Gree AC by using the isolator switch:

  • Locate the isolator switch near the front cover of the indoor air handler or on the outdoor unit.
  • Turn off the isolator switch.
  • Wait for at least 30 minutes to allow the appliance to dispel the electrostatic charge.
  • After the time has elapsed, turn the lever back to restart your unit without the problem.

Method #5: Resetting It From the Circuit Breaker

Resetting From Circuit Breaker

If you don’t have an isolator switch for your Gree AC unit, you can use the circuit breaker to reset the appliance. Note that the circuit breaker’s main function is to protect your electronics from overcurrent.

When there is an overcurrent, the circuit breaker kicks in, cutting off the electrical supply. The circuit breaker is typically that big switch with multiple switches for separate circuits in your home.

In most homes, each switch is labeled to indicate the specific connection it controls. So, for example, locating the one for the AC will help you reset your unit.

Here’s how to reset a Gree AC by using the circuit breaker:

  • Power off your Gree AC unit.
  • Locate the power outlet for the AC unit.
  • Turn off the switch on the circuit breaker that controls the AC and leave it off for up to 30 minutes.
  • After the time has elapsed, turn on the switch, and power your Gree AC.


As you can see from this guide, resetting a Gree AC unit is easier than you may have thought. However, while resetting your Gree AC may fix many issues, it does not fix all the issues with your unit. Sometimes, it takes more than resetting your unit; you may need help from a professional.

Frequently Asked Questions

What Are the Signs Your Gree AC Needs Repair?

Note that your Gree AC needs repair, not a reset, when it produces unpleasant odors and warm air from its vents.

Also, when it makes a squealing or grinding noise and your electricity bill spikes, it’s a sign you need to call a technician for repair service.

What Do I Do When My AC Refuses To Start?

Many reasons can be responsible for your AC malfunctions, such as when it won’t start. First, inspect the unit; perhaps the issue is related to a faulty electrical connection. Other times it could be that the compressor is defective.

If you can’t figure out why the AC unit refuses to start, ensure you hire a professional to inspect the unit.
