If your Gree Air Conditioner is showing an E1 error code, it means there is a High-Pressure Protection (HPP) issue. This error occurs when the outdoor unit detects high pressure for more than 3 seconds. As a safety measure, the AC shuts down to prevent damage.
When the E1 error code appears on a Gree Air Conditioner, the system automatically shuts down to prevent overheating. During this time, all buttons and remote control functions become unresponsive, except for the ON/OFF button. To reset the AC, simply turn it off, wait for a few minutes, and then power it back on. This may help clear the error and restore normal operation.
Possible Causes of E1 Error
-
Blocked or Dirty Condenser Coils
-
Dust and debris can block airflow, causing high pressure.
-
Solution: Clean the outdoor unit regularly.
-
-
Faulty Outdoor Fan Motor
-
If the fan isn’t working, heat cannot escape, leading to high pressure.
-
Solution: Check and replace the fan motor if needed.
-
-
Closed or Partially Open Valves
-
If the liquid or gas valve is not fully open, pressure can build up.
-
Solution: Ensure both valves are completely open.
