Samsung Oven: fan not turning off

Professional Repair Guide

What is this symptom?

If your Samsung oven's fan continues to run after the cooking cycle has ended and the oven has cooled down, it may be causing concern. This could be due to normal cooling operation or a malfunctioning component such as a temperature sensor or thermal switch. Understanding the potential causes can help you determine the right course of action.

Urgency: Medium

Possible Causes

Normal cooling cycle/fan operation

How to Identify: Fan runs for a period after cooking but stops once internal temperature is within safe range; no error codes or other issues

Part: Cooling fan system

Faulty temperature sensor

How to Identify: Fan runs excessively or continuously; inconsistent oven temperature during cooking; sensor reads incorrect temperature

Part: Temperature sensor

Malfunctioning thermal switch/thermostat

How to Identify: Fan stays on even when oven is cool; multimeter continuity tests show switch stuck closed

Part: Thermal switch/thermostat

Control board or fan relay stuck closed

How to Identify: Fan remains on with correct temperature readings; other control anomalies such as erratic display or functions

Part: Main control board/fan relay circuitry

Preventive Maintenance

  • Allow proper ventilation around oven: Excess heat buildup prolonging fan run
    Frequency: ongoing
  • Keep oven clean to avoid sensor obstructions: Incorrect temperature readings affecting fan control
    Frequency: monthly
