Gree Air-conditioning Error E1

What does the E1 error code mean affecting your Gree air conditioner?

Air conditioners are essential to keep us cool during the hottest months of the year, but when problems like the E1 error code arise in Gree brand units, we can become frustrated and swelter in the heat. It is important that we understand what this problem means and how we can fix it, all in order to continue using our air conditioner normally.

The E1 error code in Gree brand air conditioners usually indicates a high-pressure problem in the outdoor unit of the air conditioner. This type of error can be caused by various factors that affect the performance of the unit and require immediate attention to prevent further damage.

These are the possible causes that lead to an E1 error code appearing in Gree air conditioners. Pay attention to each of these causes so that you can apply the appropriate solution depending on the case:

• Excess refrigerant in the air conditioner: The amount of refrigerant in the circuit may be excessive, leading to high pressure in the outdoor unit.
• Very high outdoor ambient temperature: If the outdoor temperature is too high, the air conditioner may struggle to dissipate heat, leading to increased pressure in the outdoor unit.
• Lack of maintenance in your air conditioner: Lack of preventive maintenance can cause the air filter to become clogged, the condenser coil or radiator to become dirty, or refrigerant leaks, leading to high pressure in the outdoor unit.
• Faulty pressure sensor: The pressure sensor may have become damaged and is sending incorrect information to the electronic board of your air conditioner.
• Damaged PCB electronic board: The electronic board may have become damaged, affecting the management and control of the air conditioner's pressure.

These are the causes that can lead to this problem! So now we will show you the solutions you can apply to continue using your air conditioner normally.

Can the E1 error code be fixed in the Gree air conditioner?

We have prepared for you a list of solutions, tips, and advice that you can apply to definitively fix the E1 error code on Gree air conditioners. Take note of each of them and don't skip any, as they are all important to help you solve this problem with your air conditioner:

1. Turn off and disconnect the air conditioner to rule out temporary errors: This is the first thing we will do today; reset the air conditioner. This procedure helps us to rule out possible temporary errors in the air conditioner and also to reset the sensors. All you have to do is completely turn off the air conditioner and disconnect it from the electrical outlet for about 15 minutes. Once the time has passed, reconnect and turn it on to check if the E1 error code has disappeared. If the problem still persists, then proceed with the following steps.
2. Check the refrigerant level of your air conditioner: You need to make sure that the refrigerant level throughout your air conditioner's circuit is within the proper measurements according to the manufacturer's specifications. For more information, you would need to consult the user manual to check the appropriate refrigerant level for your air conditioner model. If necessary, adjust the refrigerant level and recheck if the E1 error code has disappeared. Keep in mind that to perform this procedure you need to have knowledge in refrigeration and have the appropriate tools for this task.
3. Perform preventive maintenance on your entire air conditioner: Perform a deep cleaning of the filters and make sure there are no obstructions caused by dirt, dust, etc. Clean the radiators and the coil connected to the compressor well. If necessary, replace the filters. Also, check that the water outlet is not blocked by dust and dirt as this can cause water to be discharged through the indoor unit.
4. Check that the outdoor temperature is not excessive: Air conditioners are meant to cool environments, that much is clear, but if the temperature surrounding the outdoor unit is excessively high, then the air will not be able to do its job properly. If you live in a very hot area, you can help the outdoor unit by placing some kind of roof or shading it from the sun, without obstructing the air inlets and outlets it may have. You can also help by ensuring it has regular maintenance and that there is no accumulated dirt in the filters, radiators, condenser coil, etc.
5. If the problem persists, please review everything mentioned above and follow the steps to the letter: Please carefully review the steps we have mentioned to rule out any possible cause that may have generated this error code. If you cannot identify the cause of the problem, then the PCB electronic board of your air conditioner is likely damaged and you will need to replace it, or the pressure sensor is damaged and you will need to find a replacement. If you do not feel qualified to perform this type of repair, it is best to leave the problem in the hands of Gree's professional technical service so that they can handle this situation.
6. Call Gree technical service and request a home visit for a more thorough inspection: If you have already tried everything we have mentioned and the E1 error code still appears on your air conditioner, then please contact Gree's official technical service.

Don't let your air conditioner go to waste because of this simple failure and bring it back to life. Schedule a visit from Gree's technical support!

In summary, the E1 error code on Gree air conditioners indicates that there is a problem with the outdoor unit, due to high pressure detected in it, which can be caused by: excess refrigerant, high outdoor temperature, very dirty air conditioner or lack of maintenance, damaged pressure sensor, or electronic PCB board. To find a solution to this problem, you need to follow the steps we have outlined in this article.

With nothing more to say, that would be all for today. We hope we have been of help and that you have been able to fix the E1 error code on your air conditioner.
