What is this symptom?

Experiencing a steam sensor error on your Samsung oven? This issue often occurs during the steam clean cycle, indicating a malfunction or misreading of the oven's internal sensors. It's essential to address this problem promptly to ensure your oven operates efficiently during cleaning cycles.

Urgency: Medium

Important Tips for Samsung Models

  • Samsung ovens display specific fault codes indicating temperature sensor errors recognized by internal diagnostics.

Possible Causes

Faulty or misreading oven temperature sensor

How to Identify: Error codes related to sensor faults indicate open, short, or out‑of‑range resistance; oven fails to reach required internal temperature or shows inconsistent readings during cleaning cycles. These codes often accompany sensor issues. Samsung internal diagnostics will display codes related to temperature sensor failures. See model’s user manual for exact code definitions. ‡

Part: Oven temperature sensor

Control board communication error with internal sensors

How to Identify: Persistent error codes that don’t resolve with sensor replacement or reset, inconsistent oven behavior unrelated to a specific sensor part. ‡

Part: Main control board
