Samsung Oven Error Codes — SE, C-21, C-22, E-08, tE, C-10, F1–F5 Diagnosis

Common Symptoms

• Error code displayed on the oven panel or clock display (SE, 5E, C-21, C-22, C-23, E-08, tE, C-10, F1–F5)
• Oven will not heat — error code displayed on startup
• SE or 5E displayed — control panel buttons unresponsive or erratic
• E-08 displayed after self-clean cycle — oven door locked and will not open
• C-21, C-22, or C-23 code during preheating — oven stops before reaching set temperature
• Gas oven displays C-10 — burner igniter fault, no heat
• Error codes only visible as brief flashes on clock display — easy to miss

Most Likely Causes

1. 1

   SE / 5E — Touchpad Membrane Shorted or Failed

   SE (or 5E on some Samsung display formats) indicates the control board is receiving a constant pressed-button signal from the touchpad — a short in the touchpad membrane. This typically means a single button in the membrane matrix is making continuous contact, either from physical damage, moisture intrusion, or deterioration of the conductive film under the touchpad surface. On NX58H5600SS and NE63A6511SS, the SE code disables the entire control panel as a safety measure. First response: power cycle the oven by unplugging for 5 minutes (not just a breaker flip — Samsung controls require a full power-down to reset the touchpad scanning circuit). If SE clears and does not return, a transient contact triggered the code. If SE returns consistently, try compressed air along the touchpad seam to clear any debris bridging contacts. If the code persists, the touchpad membrane must be replaced. Replacement touchpad assemblies for Samsung ranges run $40–$120 depending on model.

2. 2

   C-21 / C-22 / C-23 — Oven Temperature Sensor Out of Range

   C-21 indicates the oven temperature sensor is reading above the expected range (possible short in sensor or excessive oven temperature). C-22 indicates the sensor is reading below range (open circuit or disconnected sensor). C-23 indicates a general temperature sensor circuit fault on some Samsung models. Samsung oven temperature sensors are NTC (Negative Temperature Coefficient) thermistors — resistance decreases as temperature increases. The specific resistance spec is: approximately 1,080Ω at room temperature (70°F), increasing to approximately 1,160Ω at 350°F. This upward resistance curve is opposite to the downward curve of most NTC thermistors — it is an unusual characteristic specific to the Samsung oven sensor design. Test procedure: pull the oven out and access the temperature sensor from the back (two screws, connector on back panel). Disconnect the connector. Set multimeter to resistance. At room temperature: should read 1,040–1,120Ω. OL = open (C-22); significantly below 800Ω = partial short (C-21). Common Samsung oven sensor part: DG32-00002B.

3. 3

   E-08 — Door Latch Motor Fault (Critical After Self-Clean)

   E-08 indicates the oven door latch assembly has not completed its movement within the expected time — either failed to lock during self-clean initiation or failed to unlock after self-clean completion. The door latch motor (DE94-01745A) is a small AC motor that drives a cam mechanism to physically lock and unlock the oven door. On Samsung ovens including the NX60A6711SS and NX60BB8712SS, E-08 after a self-clean cycle is very common — the latch motor or latch position switch fails after cycling at 900°F+ oven temperatures. The latch assembly is located at the top rear of the oven cavity. Diagnosis: manually attempt to feel if the latch cam is jammed or stuck in mid-position. A failed latch motor will not respond to power cycling alone — the motor must be tested or the latch mechanism freed manually (only after oven temperature drops below 200°F).

4. 4

   tE — Oven Temperature Sensor Fault (Alternative Code Format)

   On some Samsung oven models, the temperature sensor fault appears as 'tE' (temperature error) rather than C-21/C-22/C-23. The underlying cause and test procedure are identical: the oven NTC thermistor (DG32-00002B) has failed or is reading out of range. 'tE' is more commonly seen on Samsung slide-in range models (NE58H9970WS, NE63A6511SS) with the digital touch display, while C-21/C-22/C-23 appears on the knob-select models. In both cases, the thermistor resistance at room temperature should be 1,040–1,120Ω. Also check the wiring harness from the sensor to the control board — a damaged wire at the oven door hinge area or at the back panel connector is a common source of intermittent tE codes.

5. 5

   C-10 — Gas Igniter Fault (Gas Models Only)

   C-10 indicates the oven gas igniter has not reached ignition temperature within the expected time or has failed to initiate flame. On Samsung gas ranges (NX58H5600SS, NX60A6711SS, NX60BB8712SS), the oven igniter is a round flat glow-bar igniter. A slow or failed igniter is the most common gas oven heating failure. Test: with power and gas both off, access the oven igniter (remove oven bottom panel — 2–4 screws). Disconnect the igniter connector. Measure resistance across the igniter terminals: a functional Samsung gas oven igniter typically reads 40–90Ω at room temperature. An igniter reading OL has burned out and must be replaced. An igniter reading functional on the bench but slow to glow (takes more than 60 seconds to glow orange-red) has weakened and should be replaced — weak igniters keep the gas valve closed because the bimetal sensor does not reach its trip point quickly enough.

6. 6

   F1–F5 — Control Board Fault Codes

   F1 through F5 indicate internal control board faults on Samsung ovens. F1 typically points to a stuck relay or internal board fault. F2 often indicates the oven temperature exceeds the maximum safe limit (possible runaway thermostat or stuck relay keeping the element or burner on). F3 and F4 are sensor-related board faults (similar to C-21/C-22 in some model firmware revisions). F5 indicates a board communication error with a secondary component (door latch, display board, or secondary sensor). Before replacing the control board for any F1–F5 code: perform a full 5-minute unplug reset; verify the oven sensor reads correctly (1,080Ω at room temp); verify the door latch assembly completes its travel. The control board is the most expensive repair ($80–$250) and should be the last component replaced after all sensors and mechanical components have been verified.

Quick DIY Checks

1. 1Full power reset — do this before anything else: Samsung oven control boards require a full 5-minute power removal to fully reset — a breaker flip alone sometimes does not discharge the board capacitors completely. Pull the oven's power cord from the wall (or turn off the dedicated circuit breaker and leave it off for 5 minutes). For gas ranges, do not close the gas valve unless instructed — gas valve position does not affect the electrical reset. After 5 minutes, restore power. Watch the display carefully during the boot sequence — Samsung ovens with SE codes sometimes display the code only during the first 2–3 seconds of startup before the panel locks up. If the error code does not return after the reset, monitor through one full bake cycle before concluding it was a transient fault.
2. 2Test oven temperature sensor (DG32-00002B) — C-21, C-22, C-23, tE codes: disconnect the oven from power. Pull the range away from the wall. On the back of the oven, locate the temperature sensor probe — it protrudes into the oven cavity from the back wall, with the sensor connector and wiring harness accessible from the rear. Remove the two mounting screws holding the sensor to the back panel. Disconnect the two-wire connector. Set multimeter to resistance (Ω) mode. Probe both sensor leads. At room temperature (68–72°F): Samsung oven sensor should read 1,040–1,120Ω. Below 800Ω or OL = failed sensor, replace DG32-00002B. Note: this Samsung oven sensor has an unusual upward resistance curve — resistance increases from approximately 1,080Ω at room temp to approximately 1,160Ω at 350°F. This is opposite to most NTC thermistors, which decrease with temperature. Confirm the new sensor reads 1,040–1,120Ω before installation.
3. 3E-08 door latch diagnosis and manual release procedure: E-08 after self-clean is the most critical Samsung oven code because the door is physically locked. Do NOT force the door open — the latch cam is under mechanical load and forcing it can break the latch housing or the door hinge. First, confirm the oven temperature is below 200°F — touch the oven door glass (warm but not scorching hot). If the oven is still hot from the self-clean cycle, wait until it cools completely. Once cool: power cycle the oven (5-minute unplug). On restart, the control board may command the latch motor to retract, which sometimes resolves the code after cooling. If E-08 persists and the door remains locked after two power cycles, locate the manual latch release — on most Samsung ovens (NX60A6711SS, NX60BB8712SS), there is a manual override slot at the top rear of the door frame accessible through the oven vent area. Use a long flat-blade screwdriver to manually retract the latch cam. After manual release, test latch motor DE94-01745A: disconnect the connector and measure motor coil resistance — should read approximately 100–400Ω. OL = failed motor, replace.

1. 4SE / 5E touchpad cleaning and diagnosis: confirm the code by watching it during the 5-minute power cycle boot. If SE appears within 3 seconds of power-up, the touchpad is actively shorted. Try compressed air: direct a can of compressed air along the gap between the touchpad overlay and the control panel frame — short bursts to clear any debris, crumbs, or moisture that may be bridging a contact. Do not use liquid cleaner directly on the touchpad seam. If compressed air does not clear the code, unplug the oven and disconnect the ribbon cable connecting the touchpad membrane to the control board (accessible from behind the control panel — remove the back screws of the console housing). With the ribbon disconnected, power the oven and observe: if SE no longer appears, the touchpad membrane itself is shorted and must be replaced. If SE still appears with the touchpad disconnected, the control board's scanning circuit is damaged and the board must be replaced.
2. 5C-10 gas igniter test (NX58H5600SS, NX60A6711SS, NX60BB8712SS): turn off the oven and close the gas supply valve. Disconnect the oven from power. Remove the oven bottom panel inside the cavity (2–4 Phillips screws — the panel lifts straight up and out). The oven igniter is the round flat element below the burner tube. Inspect visually — a burned or cracked element body is obvious. Disconnect the igniter connector from the harness. Set multimeter to resistance: functional Samsung gas oven igniter reads 40–90Ω. OL = burned out, replace. After installing a new igniter, restore gas and power. Watch the igniter during a bake cycle through the oven window — it should glow orange-red within 15–30 seconds of the heat call. Restore gas supply valve. Use soapy water at the igniter gas fitting connection to confirm no gas leak.
3. 6Locate and decode Samsung error codes on the display — clock display flash vs. main display: on newer Samsung slide-in ranges (NE58H9970WS, NE63A6511SS), error codes appear on the main oven display. On some older Samsung freestanding models, error codes flash briefly on the clock time display — you may miss them if not watching the panel at the moment of fault. To capture codes on clock-display models: initiate a bake cycle, watch the clock display for any sequence of flashing characters during the first 2–3 minutes of operation. Also check whether the code appears on the cooktop display (if equipped with a separate cooktop display section) — some Samsung dual-fuel models display oven faults on the cooktop status area, not the main oven panel.
4. 7Control board F1–F5 isolation before replacement: before replacing the control board (DG94-series, $80–$250 depending on model), isolate all external causes of F1–F5. Perform the 5-minute unplug reset. Verify the oven temperature sensor reads 1,040–1,120Ω (C-21/C-22 codes sharing the F3/F4 code space). Verify the door latch assembly operates freely (no E-08 present simultaneously). Verify the touchpad is not shorted (no SE present simultaneously). F2 specifically: if the oven shows F2 during or after baking, check whether the oven is overheating. Monitor actual oven temperature with an independent oven thermometer during a bake cycle — if the oven significantly overshoots the set temperature (e.g., set to 350°F but actually reaching 450°F+), a relay on the control board is stuck closed, keeping the element or burner on continuously. A stuck relay on the control board is not repairable without component-level rework; the board must be replaced.
