How to Fix E2 Error Code in Gree Inverter AC? | U-Match Series

The E2 error code in Gree Air Conditioners indicates freeze protection or icing over in the system. This happens when the evaporator temperature drops too low in cooling or dry mode. When this occurs, the compressor and outdoor fan motor automatically stop to prevent damage. The unit will not restart until the evaporator temperature returns to a safe level, with the compressor remaining off for about 3 minutes.

Causes of E2 Error in Gree AC

If your AC displays the E2 error, one of the following issues may be the cause:

1. Blocked Indoor Unit Filter

A clogged air filter restricts airflow, causing the evaporator coil to freeze.
Fix: Remove the filter and clean it with water.

2. Dirty or Blocked Evaporator Coil

Dust and debris on the coil reduce heat exchange, leading to icing.
Fix: Clean the coil using a water pressure pump or mild chemicals to remove dirt and bad odors.

3. Faulty or Dirty Indoor Fan Blower

A damaged or dirty blower affects airflow, contributing to freezing.
Fix: Inspect the blower for blockages or damage and clean or replace it if needed.

4. Slow or Faulty Indoor Fan Motor

A slow or non-functioning fan motor can cause ice buildup inside the unit.
Fix: Check the fan motor for faults and replace it if necessary.

5. Blocked Air Return or Outlet

If airflow is restricted, the AC may struggle to maintain temperature, causing freezing.
Fix: Ensure air return vents and ducts are clear for smooth circulation.

How to Fix the Gree AC E2 Error?

Follow these steps to troubleshoot and fix the E2 error in your Gree AC:

Turn off the AC and let the ice melt before restarting.
Check and clean the air filter if it is clogged.
Inspect the evaporator coil for dirt or blockages and clean it if needed.
Ensure the indoor blower fan is clean and working properly.
Test the indoor fan motor for slow speed or malfunction.
Check the air return and outlet vents to ensure they are not blocked.

When to Call a Technician?

If the E2 error continues even after cleaning and checking the above components, a professional technician should inspect your AC. The issue could be related to refrigerant levels, sensor problems, or a malfunctioning control board.

By maintaining your Gree AC regularly and keeping the airflow smooth, you can prevent the E2 error and keep your unit working efficiently.
