The EE error code in air conditioning units can have several key meanings depending on the brand of the equipment. Below, we break down these meanings and their possible solutions:
Common Meanings of the EE Error Code
Issues with the Control Board and EEPROM Memory
- For most brands, the EE code is associated with problems in the electronic control board, specifically in the EEPROM memory of the affected module.
- Brands like TCL, Carrier, GREE, Pioneer, among others, use this interpretation for the EE code.
Water Drainage Problems
- Some brands associate the EE code with issues in draining water generated by air humidity condensation.
- Brands such as Midea, Lennox, York, and Acer, among others, use this meaning for the EE error code.
Troubleshooting EEPROM Memory Failures
1. Reset the Unit
- Turn off the unit and unplug it from the power source.
- Wait several minutes before reconnecting and powering it back on.
2. Initial Observation
- Check if the EE error appears immediately.
- In many cases, if the issue lies in the EEPROM memory, the error code may change its value or number multiple times.
3. Inspect the Control Board
- Visually examine the electronic module where the error occurs.
- Locate the controller on the board and the nearest integrated circuit with eight terminals on each side.
4. Check Resistors Near the EEPROM Memory
- Inspect if any resistors near the EEPROM memory have abnormal values.
- Carefully replace any defective resistors.
5. Test Operation
- Once the resistor is replaced, operate the unit again to check if the error has disappeared.
6. Replace the EEPROM Memory
- If the error persists, replace the EEPROM memory with one that has the correct programming or comes from a control board of the same model.
- The EEPROM memory is a type of non-volatile storage that retains configurations and data even when the unit is powered off.
Troubleshooting Water Drainage Failures
1. Reset the Unit
- Unplug the unit from the power source for several minutes and check if the error persists.
2. Access the Drainage System
- Remove the covers of the indoor unit to access the drain pan and drainage tube.
3. Inspect for Moisture and Leveling Issues
- Check the indoor unit for excessive moisture, mold, or stagnant water.
- Ensure the unit is properly leveled to allow adequate drainage.
4. Inspect and Clean the Drainage Tube
- Ensure the drainage tube is not bent or blocked.
- Clean the drain pan with soapy water and a soft brush to remove dirt and mold.
5. Check Drain Pump Functionality (if applicable)
- If your unit has a drain pump, ensure it is working correctly.
- Listen for the pump activating and expelling water appropriately.
