VERIFIED
This code is about two circuit boards that no longer talk to each other. On the Bertazzoni REF36FDFZXNT, CA is defined as a failure of communication between the main control board and the ice making board.
Two boards, one job
The main control board runs the refrigerator. The ice making board looks after the ice maker side. They exchange information, and when that exchange stops, the refrigerator posts CA. The manual stops there. It gives no cause, such as a wiring fault or a failed board, and no steps for the owner.
How the alarm behaves
| Situation | What the manual says |
|---|---|
| Panel locked | The code shows in the temperature display area |
| Several faults | Codes cycle and a chime sounds |
| Silencing | Press any button |
| After the repair | The code disappears from the display |
What we suggest
Because the fault is between electronic boards, there is nothing for a homeowner to adjust. Skip any internet advice about unplugging boards or swapping connectors. Write down the code and arrange service.
Why this one needs a technician
Nothing in the owner manual lets you reseat, reset or test either board, and both boards are electronic parts that are not meant to be handled. A communication fault can come from either end of the link or from the connection between them, which is exactly the sort of question a technician answers by testing instead of guessing.
