What to do if there is a communication failure between the indoor unit and outdoor unit in my Friedrich FPHFW09A3A Air Conditioner?
- G
  grayrobinSep 12, 2025
  If your Friedrich Air Conditioner is experiencing communication failure between the indoor and outdoor units, there are several potential causes. First, check the communication cable connector to ensure it is secure. If the connector is fine, the communication cable itself may have failed and need replacement. Also, verify the connection between the filter board and both the outdoor control board and the terminal, ensuring they are correctly connected and not loose. Other potential causes include a failed indoor control board, PFC board, power board, or outdoor control board, any of which would require replacement.
