VERIFIED
A C9 code on a Bertazzoni refrigerator with an ice maker points at one specific place: the ice making chamber. The error table in the REF36FDFZXNT user manual words it as “the sensor in the ice making chamber has failed.”
What the manual says about the display
Error codes show in the digital temperature display area while the panel is locked. If the refrigerator detects more than one fault, the codes rotate on screen and an alarm chime sounds. Pressing any button silences the chime, locked or unlocked. Once the underlying problem is fixed, the code goes away by itself.
What it means in practice
The ice maker uses sensors to know what is happening in its chamber. If one of them reports a failure, the control board no longer has a trustworthy reading from that spot. The manual does not give causes or owner checks for C9, and it lists no reset. So the honest advice is brief:
- Silence the chime if it bothers you, and note the code.
- Do not take the ice maker apart or pull wiring out of the chamber.
- Have a technician look at it.
Using the ice maker meanwhile
The manual does not tell owners to stop using the ice maker when C9 appears, and it does not promise that ice production continues. If it is making ice normally, you can keep using the bin, but check any ice you intend to serve.
Neighbors in the same table
The ice maker has several codes of its own, so check which one you are actually seeing:
- CC: the ice maker defrost sensor
- CA: a communication break with the ice making board
- F4: the ice maker sensor, listed separately

Call (415) 692-0756 for a C9. It helps to have the model number from the nameplate and to tell us whether the ice maker is on or off.
Model compatibility: Bertazzoni reuses codes across series and model years, so C9 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
