Frequently Asked Questions

Can I still use my Samsung oven with error code E27?
No, you should not use your oven with error code E27. The temperature sensor failure means the oven cannot accurately control heat, which can lead to undercooked food or overheating that could damage the oven or create a fire hazard.
How much does a Samsung oven temperature sensor cost?
Samsung oven temperature sensors typically cost between $25-60 depending on your model. Generic compatible sensors may cost $15-30, but ensure compatibility with your specific Samsung oven model number.
What causes Samsung oven temperature sensors to fail?
Temperature sensors commonly fail due to age, repeated heating and cooling cycles, moisture exposure, or physical damage. Most sensors last 5-8 years with normal use before requiring replacement.
Will error code E27 reset itself on Samsung ovens?
No, error code E27 will not reset itself. The error persists until the faulty temperature sensor is replaced or the wiring issue is repaired. The oven's control system continuously monitors the sensor and will keep displaying E27 until the problem is fixed.
How do I find the right temperature sensor for my Samsung oven?
Check your oven's model number (usually found inside the door frame or on the back panel) and search for 'Samsung oven temperature sensor' plus your model number. The sensor should have specifications matching your oven's requirements, typically 1080 ohms at room temperature.
