U-Match Series DC Inverter Service Manual – E1 Error Code
Gree AC Error Code E1 Troubleshooting.
In This Post, We are describing here about E1 error in Gree Air Conditioners. E1 error gives us an indicator for defected or faulty HPP Switch or High Pressor Protection.
When the external unit detects that the high-pressure switch is cut sequentially for 3 s, there will be high-pressure protection. All loads (except 4-way valves in heating mode) will be switched off. In this case, all buttons and remote control signals except the ON / OFF button will be disabled and cannot be retrieved automatically. To eliminate this protection, turn off the unit after a power cut or reactivate the unit.
- If there is a High-Pressure Protection error in the display, maybe your outdoor fan motor also faulty. The heat will not be exhaust due to not working fan motor.
- you have to double-check for your liquid valve and gas valve open completely.
