Samsung Oven E-08 Error — Temp Sensor Open

What Does This Error Mean?

E-08 means the oven temperature sensor circuit reads as open — the control board can't talk to the sensor.
Either the sensor itself has failed, or the wiring or connector between the sensor and the board has broken.
Cut power for 10 minutes and try again — if E-08 returns immediately, the sensor needs replacing.
It's a service repair on most Samsung models, but the part is cheap.

Affected Models

Samsung NE63T8511SS
Samsung NV51K7770SS
Samsung NX60T8511SS
Samsung NE58F9710WS
Samsung NV75K5571RS

Common Causes

Failed oven temperature sensor (RTD probe)
Broken or pinched wire between sensor and control board
Loose or corroded connector at the back of the sensor
Sensor damaged by a metal item making contact with it
Control board input fault (rare)

How to Fix It

Cut power at the breaker for 10 minutes.

Flip the dedicated oven breaker fully off.
Some E-08 events from a transient sensor read clear after a proper cold restart.
If E-08 returns the moment power comes back, the sensor or wiring is genuinely faulty.
Inspect the sensor inside the oven cavity.

The sensor is a small metal probe sticking out of the back-left or back-right wall, near the top.
Look for damage — bent probe, melted connector, or visible burn marks.
A probe that's been hit by a baking sheet often shorts internally.
Check the harness if the probe looks fine.

Pull the oven away from the wall and remove the rear access panel.
Trace the sensor wire to its connector at the control board.
A loose connector — easy to spot — is the cheapest fix on this code.
Book service for sensor replacement.

Samsung oven temperature sensors are usually a single-screw replacement once the back is off.
The technician will test the new sensor with a multimeter before reassembling.
Healthy sensor reads about 1080 ohms at room temperature.

When to Call a Professional

E-08 is a service repair.
The sensor itself costs $20–$50, but accessing it requires removing the back of the oven.
An appliance technician handles the swap in 30–60 minutes — typical cost $150–$250 fitted.

Frequently Asked Questions

Can I replace the Samsung oven temperature sensor myself?

Yes if you're comfortable with appliance work.
Pull the oven from the wall, remove the back panel, unscrew the sensor from the cavity, swap in the new one, reconnect.
Total time is about 30 minutes.
The part costs $20–$50 from any appliance parts supplier with the model number.

Why does my oven say it's working with E-08 sometimes?

Some Samsung models default to a fixed temperature value when the sensor reads as open.
The oven runs but actual temperature is uncontrolled — it can be wildly off the set point.
Don't trust the temperature display while E-08 is active.
Use an oven thermometer if you must cook anything before the repair.
