Samsung Oven SE Error Code: What It Means and How to Fix It

Last updated: October 5, 2026 · Codes covered: SE, C-d0 · Sources

Verify in your manual: Samsung's US range error page doesn't list SE by name; the meaning comes from Samsung owner's manuals, and newer models show C-d0.

An SE code on a Samsung range or wall oven means the control thinks one of the touch keys is shorted or stuck down. Sometimes it's just moisture, grease, or something resting on the panel, and a clean and a reset will clear it. If the code keeps coming back, the keypad (touch panel), its cable, or the control board usually needs replacing.

On some displays, SE looks like 5E. It's the same code. Newer Samsung ranges show the same problem as C-d0.

What the SE code means

Samsung's owner's manual for the NX58F5500SS/NX58F5300SS gas ranges lists SE as a "Shorted Key." Newer manuals, such as the one for the NE63A6511SS electric range, use C-d0 and say "there is a short in the control key." Either way, the electronic control is seeing a button signal that doesn't stop. A key looks permanently pressed, or there's a short in the keypad or its wiring.

AppliancePartsPros, a parts retailer, describes SE (or 5E) the same way: a shorted key on the control panel keypad. They name three causes: a shorted keypad, a problem with the wiring connection, or a bad main control board.

What you'll notice: the oven controls may stop responding, or a cooking function may stop.

Look-alike codes that mean something different:

• C-d1 on newer Samsung ranges means the door lock is misaligned. It's not a key problem.
• C-F2 means communication between the main board and the touch panel was interrupted. It's related, but it's not a stuck key.

Samsung's US range error code page doesn't list SE by name. It's covered by Samsung's steps for "all other error codes" (below). Codes and panels vary by model, so check the "Information codes" section of your owner's manual.

Likely causes (most common first)

1. A temporary electronics glitch that a reset clears. That's why Samsung's first steps are a restart and a power reset.
2. Something on the panel, like a pot handle, utensil, or sticky spatter holding a key down. AppliancePartsPros lists debris keeping a button pressed as something to check.
3. Moisture or steam on the control panel, from boil-overs, steam, or a wet cleaning cloth.
4. A worn or damaged keypad, for example a bubbled, cracked, or peeling membrane, or a key that feels stuck.
5. A loose, damaged, or corroded keypad cable between the touch panel and the control board.
6. A faulty control board. This is less common, and usually only the culprit once the keypad and cable check out.

How to fix it, step by step

Try the range again after each step.

1. Clear the panel. Move pots, utensils, towels, and anything else off or away from the control area.
2. Dry and clean the keys. Let the range cool. Wipe the control panel with a soft, barely damp cloth, then dry it thoroughly. Don't spray cleaner directly onto the panel, because liquid can seep under the keys. If steam or a spill just hit it, give it time to dry out before you try again.
3. Press OFF/CLEAR (or the Power button) and restart. Samsung's manuals say to press OFF/CLEAR and then restart the oven. Samsung's support page says to turn the range off and back on with the Power button.
4. Reset the power. If SE comes back, turn off the circuit breaker for the range, wait at least 30 seconds, then turn it back on. Samsung gives this step in both its manuals and its support page. On a gas range, the breaker or plug only powers the electronics and igniters, so you don't need to touch the gas.
5. Check each key. Look for a key that looks dented, swollen, or stuck. Press each key once. A key that doesn't spring back, or that triggers without a press, points to a bad keypad.
6. Watch for patterns. Does SE appear only when the cooktop is on, or after cleaning? That suggests moisture or heat getting into the panel, which is useful information for the technician.
7. Call for service if it keeps coming back. At this point the keypad (touch control), its cable, or the control board needs to be checked and replaced. See "Test the part" for safe checks you can do, or request Samsung service.

Test the part

The part behind SE is the keypad (touch control) and its cable, and sometimes the main control board. Here are safe, unplugged checks.

1. Unplug the range or switch off its breaker. Wait at least 30 seconds. For gas ranges, cutting the power is enough for these checks; you don't need to touch the gas. But don't pull a gas range out far enough to strain the gas connector.
2. Check the panel surface. With the power off, look across the keys in good light. Bubbling, cracks, a lifted edge, or moisture under the glass or film are signs of a failing keypad.
3. Check the cable connection (only if you're comfortable removing panels). On many Samsung ranges, the keypad cable plugs into the main board behind the control panel or rear cover. AppliancePartsPros shows this on models starting with FCQ321HTU, which have the connector labeled CN05. Layouts vary, so check your model's documents.
   • Photograph the connectors before touching them.
   • Make sure the keypad cable is fully seated. Look for corrosion, burn marks, cracks, or creases in the ribbon.
4. Optional keypad continuity check. If your model's wiring diagram identifies the key circuits, set your meter to continuity or the lowest ohms setting.
   • With the key not pressed, the circuit should be open (OL).
   • Press the key: it should show continuity, then go back to OL when you let go.
   • A circuit that shows continuity with no key pressed is a shorted key, which means a new keypad.
   • Don't guess pin numbers. If there's no diagram, skip this test.
5. Reassemble before restoring power. Replace every panel and screw first.

Stop and call a pro if you can't identify the connector or the key circuits, the keypad and cable look fine but SE returns, or the range is under warranty. Control board checks need power on, and those aren't DIY tests.

Safety notes

When to call a pro

Request Samsung service or call a qualified appliance technician if:

• SE (or C-d0) returns after cleaning, drying, and a 30-second breaker reset.
• A key is visibly damaged or the panel is cracked.
• You see burn marks, melted connectors, or corrosion behind the panel.
• The range is still under warranty. Check your coverage before opening it.

Samsung's US manuals list 1-800-SAMSUNG (1-800-726-7864) for service, and you can request service through samsung.com/us/support.
