Question:

What does Error Code 45E or 45C mean on my refrigerator and how can it be resolved?

Answer:

 Error Code 45E or 45C indicates a Communication Error for Dual Compressors style refrigerators. This error code can appear due to issues with the main PCB (Printed Circuit Board) or the Refrigerator Inverter PCB. Here's what you need to know and how to resolve the issue:

PCB main defect - The main PCB may be faulty, causing the error code to appear. To fix this, a professional technician may need to replace or repair the main PCB.

Refrigerator Comp. Inverter PCB defect - The Refrigerator Compressor Inverter PCB may also be defective, leading to the appearance of the error code. Similar to the main PCB, a professional technician may need to replace or repair the Inverter PCB to resolve the issue.

Loose wire connection between 2 boards - Sometimes, loose connections between the two PCBs can cause communication errors, triggering the error code. Check the connections between the main PCB and the Refrigerator Compressor Inverter PCB, and ensure that all wires are securely connected. If necessary, consult a professional technician to check and tighten any loose connections.

In case the problem persists after trying these solutions, it is recommended to contact a professional technician for further diagnosis and repairs.
