Question:

What are the possible reasons for Error Code 44E or 44C: PCB Main Inverter Communication Error in a dual compressor freezer?

Answer:

PCB main defect - The main Printed Circuit Board (PCB) may have an issue causing the communication error.

Freezer Comp. Inverter PCB defect - The Inverter PCB specifically for the freezer compressor might be faulty, leading to the communication error.

Loose wire connection between 2 boards - There could be a loose or damaged connection between the main PCB and the freezer compressor's Inverter PCB, causing the communication error.

Terms:

Error Code - Refers to specific numbers or codes displayed when an appliance encounters an issue.

PCB (Printed Circuit Board) - A board containing electronic components and connections allowing signals to pass between them.

Inverter - A device that changes direct current (DC) to alternating current (AC).

Compressor - A component in refrigeration systems that compresses and circulates refrigerant gas.

Dual Compressors - A refrigerator featuring two separate compressors for the fridge and freezer sections.

Loose Wire Connection - Refers to a loose or damaged connection between electronic components, which can cause issues in communication and function.
