EC51, EH00, and EH0A Error CodesUpdated an hour ago
The "EC51", "EH00", and "EH0A" error codes indicate an EEPROM parameter error.
- EC51 Error Code: Outdoor unit EEPROM parameter error
- EH00 Error Code: Indoor unit EEPROM error
- EH0A Error Code: Indoor unit EEPROM parameter error
The main chip on the indoor or outdoor PCB is not receiving a signal from the EEPROM chip.
Recommended Parts to Prepare
- Indoor unit PCB
- Outdoor unit PCB
Notes
- An EEPROM (electrically erasable programmable read-only memory) is a type of memory whose contents can be erased and reprogrammed using a pulsed voltage. The images below show the location of the EEPROM chip on the indoor and outdoor PCBs. These images are for reference only; actual appearance may vary.
- For EEPROM parameter errors on the compressor driver chip, and communication errors between the outdoor main chip and the compressor driver chip, follow the same troubleshooting procedure as for EC51.
