Samsung Oven: slow to preheat
What is this symptom?
Is your Samsung oven slow to preheat? If it takes more than 20-30 minutes to reach 350°F, you may experience delayed cooking times and uneven food results. This issue can stem from a faulty heating element, airflow obstructions, or in rare cases, control board malfunctions. Understanding the causes can help you get your oven back to optimal performance.
Important Tips for Samsung Models
- Samsung states normal preheat to 350°F should occur within ~20 minutes under typical conditions; longer times suggest service.

- Defective temperature sensor
- Malfunctioning control board
User Suggested Solutions
-
Replace the faulty igniter. First, disconnect the oven from power. Remove the oven bottom panel to access the igniter. Disconnect the igniter wires and replace it with a new one. Reassemble the panel and reconnect the power.
-
Test and replace the temperature sensor. Use a multimeter to check the sensor's resistance. If it is out of range (typically 1080-1100 ohms at room temperature), replace it. Disconnect power, remove the sensor from the oven wall, and install a new one.
-
Inspect and replace the control board if necessary. This requires removing the oven's back panel. Check for burnt components or signs of damage. If found, replace the control board with a new one, ensuring all connections are secure.
