Samsung Error Code E-27
Oven temperature sensor open/short
Common Causes
- 1Sensor disconnected
- 2Wiring damage
Do not bypass the temperature sensor to use the oven. Without temperature feedback, the oven has no overheat protection and can become a fire hazard.
Step-by-Step Troubleshooting
- 1
This is a more specific version of the tE code — E-27 explicitly indicates an open or shorted circuit in the temperature sensor wiring
- 2
Turn off the breaker and access the sensor connector at the back of the range. Disconnect and reconnect the sensor plug to rule out a loose connection
- 3
Measure resistance at the control board end of the sensor harness: should be approximately 1,080 ohms at room temperature. OL (open) = broken wire or disconnected sensor. Near zero = shorted wire or sensor
- 4
If resistance at the board connector differs from resistance at the sensor itself, the wiring between them is damaged. Trace the wire path for breaks — especially where wires pass through the oven insulation
Pro Diagnostic Tip
E-27 appearing after oven self-clean is a classic sign of heat-damaged sensor wiring insulation. Self-clean temperatures (900 °F+) can exceed the wire insulation rating where the harness passes near the oven cavity. Look for wire insulation that has turned brittle and brown.

- •Error appears immediately when oven is turned on
