Samsung C-A2 Error Code — Oven / Range Fault Fix

Error Code Explained

What Does the Samsung C-A2 Error Code Mean?

The C-A2 error code on a Samsung range (also displayed as CA2) is a secondary communication fault — closely related to C-A1 but typically indicating a fault between the main board and a different sub-module, such as the cooktop induction board or a secondary control processor. On some models C-A2 is a follow-on to C-A1 when multiple communication paths are affected.

Root Causes

Common Causes of the Samsung C-A2 Error Code

1

Failed Cooktop Control Module

On induction ranges, the cooktop induction board has stopped communicating with the main PCB.
2

Damaged Communication Harness

The harness between the main board and the secondary module is damaged or has a broken wire.
3

Main PCB Communication Circuit Failure

The main board has multiple communication channels; C-A2 indicates a different channel has failed than C-A1.

How to Troubleshoot the C-A2 Error Code

⚠️

Safety First: Always disconnect the Oven / Range from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Power reset

Turn off the circuit breaker for 5 minutes. Restore power and test. If C-A2 clears and does not return, the fault was a transient communication error.
