Need help with error codes on your Gree AC? Please leave a question below and we will be happy to help.

Hello E, I appreciate your post!
I see that your Frigidaire air conditioner is displaying an error code of "H1". I have reviewed the air conditioner and the "H1" error code could be an "HI". The "HI" error code means that the room temperature is above the display range. I would recommend performing a reset on your air conditioner. In order to reset the air conditioner you need to unplug the power cord you can press the reset button and then the test button that should restart your air conditioner. If that does correct your issue I would recommend seeking assistance from a professional technician for proper diagnosis and repair. I hope this information is helpful for you. -Matt
