EE Moderate Hard — consider a tech

LG Microwave EE — EEPROM / control memory error

LG Microwave · Error code EE

What EE Means

The control board cannot read or write its EEPROM (non-volatile memory). Settings and calibration data are inaccessible, so the microwave refuses to operate normally.

Symptoms

  • EE on display
  • Unit boots straight to the error
  • Power-on cycle does not clear it

Common Causes

1
Corrupted EEPROM data

Power surge or brownout during a write.

2
Failed EEPROM chip

Memory IC on main board has died.

3
Main control board failure

Other board-level fault preventing memory access.

How to Fix It

  1. Unplug for at least 5 minutes; some EE faults clear after a long power cycle.
  2. Plug back in and observe; if EE persists, the board needs service.
  3. Service note: this is almost always solved by replacing the main control board.
  4. Order the exact OEM main control board for your model number (label inside door or on cabinet).
