In brief

Fault code EE on Gree All ranges means: Fault code EE (or E-E) means the processor cannot read data from the EEPROM memory (the 'brain' that stores settings). Most common cause: Temporary software bug, strong magnetic interference, or faulty memory chip. First action: Isolate the power supply at the circuit breaker for 5 minutes.. Call a registered engineer if the fault returns after basic checks or involves refrigerant work (F-Gas registered engineer required).

According to the Gree service manuals, if the ODU main board cannot read the EEPROM memory, it must be replaced.

What does fault code EE on Gree mean?

Fault code EE (or E-E) means the processor cannot read data from the EEPROM memory (the 'brain' that stores settings).

Temporary software bug, strong magnetic interference, or faulty memory chip.

Symptômes

Air conditioning locked
Fixed EE display

Diagnostic

1. Power reset

Isolate the power supply at the circuit breaker for 5 minutes.
Restore power. If the error clears, it was a temporary bug.

How to reset fault code EE on Gree?

Perform a power reset. If the error returns immediately, replace the main electronic control board.

When should you call an F-Gas engineer?

This code occurs when the outdoor unit is powered but unable to communicate with its configuration memory. The installer should visually check the chip installation and the condition of the solder joints before concluding a hardware failure of the main electronic board or the control panel.

Affected models

Flexx Eco
Flexx Ultra R32
High Static Slim Duct
Universal Floor Ceiling
Livo Plus

Field context

Technical source data

Fault code EE indicates a read/write fault of the EEPROM memory chip on the outdoor unit (ODU) main board or on the drive board. Identified causes include a damaged memory chip, weak solder joints, or short circuits on the chip tracks. According to the service manuals, if the ODU main board cannot read the memory, it must be replaced. For specific models (e.g., Livo Plus), the code may display with specific flashes (e.g., 3s OFF, 15 flashes) and requires replacement of the outdoor control panel AP1. The failure causes the compressor to stop in cooling mode (indoor fan remains active) or a complete unit shutdown in heating mode.

Questions fréquentes

What are the operational symptoms when fault code EE appears?

In cooling or dehumidification mode, the compressor stops while the indoor fan continues to run. In heating mode, the entire unit stops. The code is displayed on the LED screen of the outdoor unit (ODU) main board.

What is the diagnostic procedure if fault code EE persists?

First, check if the memory chip is correctly installed on the drive board. If the chip is present, inspect the solder joints and tracks for short circuits or deformation. If the chip is damaged or poorly soldered, or if the board still cannot detect the memory, replace the outdoor unit (ODU) main board or the control panel.

Is fault code EE specific to certain ranges like Livo Plus?

Yes, for some ranges like Livo Plus, fault code EE is accompanied by a specific display pattern: 3 seconds off, 15 flashes, 1 second off, 11 flashes. The solution remains the same: replace the outdoor control panel AP1.
