Compatible With:

This board is specifically designed for the 8kW variant of the F2040 series, which uses different control hardware compared to the 12kW and 16kW models.

Key Functions

• Suppresses electromagnetic interference (EMI) from high-power components (e.g., fan, compressor)

• Ensures reliable communication between the inverter board, control module, and external controllers (like SMO or VVM)

• Helps maintain stable operation in noisy electrical environments

When to Replace

• Communication errors between components

• Irregular modulation of compressor or fan

• System fault codes indicating control instability or EMI-related issues

• During main board servicing or full unit refurbishment
