Samsung Oven/Range E-27 Error Code: Causes & Fix

What is the Samsung Oven/Range E-27 error?#

An E-27 code on your Samsung oven or range means the oven temperature sensor circuit is open or shorted — the control has lost a valid connection to the sensor entirely, not just a drifting reading. The oven refuses to heat and the error often appears the instant you turn it on. A very common backstory is that E-27 shows up right after a self-clean cycle, whose extreme heat can damage the sensor or its wiring. There is no immediate hazard, but the oven is unusable for baking. Start with a power cycle at the breaker in case the fault was transient.

E-27 on a Samsung Oven/Range: likely causes and repair cost#

On a Samsung Oven/Range, the E-27 code signals: oven temperature sensor open/short.

Typical professional repair: $100–$275 · Difficulty: hard · usually a technician job

Symptoms that often accompany E-27: Oven completely refuses to heat; Error appears immediately when oven is turned on; Error appeared after running a self-clean cycle

Technician diagnostic sequence for E-27:

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

Parts a technician may check or replace: Samsung DG32-00002B; model-specific

Field note: 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.

Safety note: 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.

How to troubleshoot the E-27 error yourself#

E-27 leaves modest room for DIY because it is a circuit fault. Power the oven off at the breaker for several minutes and restart to clear a one-off. If E-27 followed a self-clean, let everything cool fully first. Beyond that, the causes in the table above — a disconnected sensor or damaged wiring — are a "hard" repair. Where the sensor plugs into the harness at the back of the cavity, a connection cooked loose by self-clean heat, or a broken wire, is exactly what causes an open circuit, and tracing that safely needs a technician with a meter. If the reset does not restore heat, stop there and book service rather than pull the rear panel yourself.

Is the Samsung Oven/Range E-27 error worth fixing?#

E-27 is generally worth fixing on a range with life left. The table above lists $100 to $275 to reconnect or replace the sensor and its wiring and restore heating — an affordable-to-mid-range repair. Against a new range that is a small share, so I fix it in most cases. The judgment only shifts on an old unit already showing other faults; a lone E-27 on a sound range is comfortably worth the $100 to $275, particularly since the fix is sometimes just repairing a self-clean-damaged connection.

Samsung Oven/Range E-27: frequently asked questions#

What does the E-27 error mean on a Samsung Oven?#

It means the oven temperature sensor circuit is open or shorted, so the control has lost the sensor connection entirely. The oven refuses to heat.

Is it safe to keep using a Samsung Oven that shows the E-27 error?#

There is no immediate hazard, but the oven will not heat until repaired. It often appears after a self-clean cycle.

Can I clear the E-27 error myself, or do I need a technician?#

Let the oven cool and reset it at the breaker to rule out a transient fault. An open or shorted sensor circuit itself needs a technician to trace and repair.

How much does it cost to repair the E-27 error on a Samsung Oven?#

The table above lists $100 to $275 to reconnect or replace the sensor and its wiring.

Which parts usually fail when an oven throws the E-27 code?#

A disconnected oven sensor or damaged wiring, per the table above, frequently caused by self-clean heat.

Why does a disconnected sensor trigger the E-27 error?#

An open or shorted sensor circuit gives the control no valid resistance to read, so it cannot judge cavity temperature and flags E-27, refusing to heat for safety.
