Samsung Oven: fan not turning off
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.
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

User Suggested Solutions
-
Check and replace the temperature sensor. Unplug the oven, locate the sensor (usually at the back or side), disconnect it, and replace it with a new one.
-
Inspect the control board for stuck relays. Unplug the oven, remove the control panel, check the relays, and replace the control board if necessary.
-
Test and replace the thermostat. Unplug the oven, access the thermostat, use a multimeter to check for continuity, and replace if defective.
