What Does E-27 Error Mean on Samsung NE63T8111SS?

Error E-27 on Samsung NE63T8111SS: Oven temperature sensor open circuit detected. Follow the troubleshooting steps below to diagnose and fix this range issue. The E-27 error code on your Samsung NE63T8111SS range indicates the control board detected an open circuit in the oven temperature sensor loop — the sensor is not returning any resistance reading. The board cannot safely allow the oven to heat when it cannot monitor temperature, so it disables the heat and displays E-27. This error is usually caused by a physically broken sensor or a disconnected harness connector. ## What Does E-27 Mean? The E-27 error means the NE63T8111SS oven temperature sensor has an open circuit, which the control board detects because the sensor’s resistance climbs above approximately 2,950 ohms. A working sensor at room temperature reads about 1,080 ohms; an open circuit reading far exceeds this threshold. The oven temperature sensor is a critical safety component. Without a functioning sensor, the control board cannot determine when the oven reaches the set temperature or detect unsafe overheating. The board’s response to E-27 is to prevent heating entirely, which is the correct protective behavior. E-27 is closely related to E-28, which indicates a short circuit in the same sensor loop. E-27 means the circuit is open (broken or disconnected); E-28 means the circuit is shorted (resistance too low). Both are resolved by testing and replacing the sensor or its wiring harness. ## Possible Causes 1. Physically damaged or broken oven temperature sensor probe — the most common cause of E-27 2. Disconnected wiring harness connector between the sensor and the main control board 3. Broken wire in the sensor harness caused by repeated heating and cooling cycles fatiguing the wire insulation 4. Sensor probe contacted by a sharp object or oven rack that damaged the wiring connection 5. Failed main control board temperature-sensing circuit — rare; only suspect after confirming sensor and wiring are intact ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Disconnect all power to the range at the circuit breaker | Range is completely de-energized | | 2 | Locate the oven temperature sensor — a thin metal probe mounted in the upper-rear corner of the oven cavity, secured by one or two Phillips screws | Sensor probe is identified | | 3 | Disconnect the sensor harness connector inside the oven cavity; measure sensor resistance with a multimeter set to ohms — at room temperature the correct reading is approximately 1,080 ohms; if resistance reads above 2,950 ohms or shows OL (open loop), the sensor is open-circuit and must be replaced | Sensor resistance value is determined | | 4 | If sensor resistance is approximately 1,080 ohms and the sensor itself is good, trace the wiring harness from the sensor toward the control board and check each connector for looseness or corrosion; also test harness continuity with the multimeter | Wiring harness is intact with no open circuits or loose connectors | | 5 | If a connector is loose or a wire is broken, repair or replace the harness section; if the sensor is defective, replace it — verify the replacement part number against your exact model number before ordering | New sensor or repaired harness is installed correctly | | 6 | Restore power and run a bake cycle to confirm E-27 has cleared and the oven heats to the set temperature | Oven heats normally and E-27 does not return | The oven will not heat while E-27 is active — this is intentional. Do not attempt to bypass the temperature sensor circuit. Operating the oven without a working temperature sensor could allow uncontrolled overheating. ## When to Call a Technician Contact Samsung authorized service if: - The sensor replacement and harness inspection confirmed both are intact, but E-27 persists — suggesting a control board fault

  • The sensor harness is routed through an area that requires disassembly beyond the basic oven cavity access
  • You are not comfortable testing resistance with a multimeter or identifying the correct replacement part number Professional repair costs for E-27 issues typically range from $80 to $250 depending on the specific component and your service region. ## Frequently Asked Questions ### What resistance should the oven temperature sensor read on my Samsung NE63A6511SS? At room temperature of approximately 72°F (22°C), the oven temperature sensor should read approximately 1,080 ohms. The E-27 error triggers when the sensor resistance rises above 2,950 ohms, which indicates an open circuit. The E-28 error triggers when resistance drops below 930 ohms, which indicates a short circuit. A healthy sensor reads between 880 and 1,280 ohms at room temperature.

Can I still use the stovetop surface burners while E-27 is active? The surface burner elements and the oven system are on separate circuits in the NE63A6511SS. E-27 only disables oven heating — the cooktop radiant elements should continue to operate normally while the oven error is active. However, do not attempt to bake or broil until E-27 is resolved.

How do I access the oven temperature sensor on my Samsung NE63A6511SS? The oven temperature sensor is mounted in the upper-rear corner of the oven cavity. With the oven completely cool and power disconnected, look for a small metal probe about 2 inches long at the top-rear of the cavity. It is held in place by one or two Phillips screws. Remove the screws, pull the probe forward, disconnect the two-wire harness connector, and the sensor is free for testing or replacement.

Why did my oven temperature sensor fail? Oven temperature sensors typically fail from repeated thermal cycling — the sensor expands and contracts thousands of times over its service life, and the internal resistance element eventually breaks down. Self-clean cycles are especially hard on sensors because temperatures above 800°F place extreme stress on the probe. The sensor should last 5–15 years under normal use but may fail sooner if self-clean cycles are run frequently.

If error E-27 does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the range with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error E-27 on a Samsung NE63T8111SS? Repair costs for error E-27 on the Samsung NE63T8111SS range depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Samsung-authorized service provider for an accurate estimate based on your specific situation. ### What does error code E-27 mean on a Samsung range? Error code E-27 on Samsung range models indicates Oven temperature sensor open circuit detected. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed. Refer to the troubleshooting steps above for guidance on resolving this issue.
