Samsung Oven: fan running continuously

Professional Repair Guide

What is this symptom?

If your Samsung oven's fan is running continuously, it may be frustrating. This issue typically occurs when the internal cooling or convection fan remains active beyond the normal cool-down period after cooking. While it could simply be part of the cooling cycle, a faulty temperature sensor might also be to blame. Understanding the cause can help you address the problem effectively.

Urgency: Medium

Important Tips for Samsung Models

  • Samsung official support states cooling fan runs after cooking until internal electronics cool; if fan never turns off, consider contacting support.

Possible Causes

Normal cooling cycle operation

How to Identify: Fan runs for up to ~30 minutes or more after a high‑temperature cycle, especially after self‑cleaning; oven otherwise functions normally. This is expected behavior per Samsung support.

Part: Cooling fan system

Faulty temperature sensor

How to Identify: Fan runs continuously with apparent normal oven temperature; oven may have inconsistent temperature control during cooking.

Part: Temperature sensor (thermistor)
