Samsung NX58H5600SS Gas Range Problems & Error Codes — Overview
The Samsung NX58H5600SS is a 30-inch freestanding gas range with a five-burner cooktop and a convection oven. This model uses Samsung information codes displayed on the control panel to indicate faults or abnormal conditions. Many codes clear with a simple power reset (flip the breaker for 60 seconds), but some point to specific hardware problems like sensor failures, partition issues, or a stuck keypad. Demo mode is a frequent cause of no-heat complaints because the oven and cooktop will not heat when this showroom setting is active.
Common hardware failures include the oven temperature sensor, main control board, and membrane keypad assembly. Samsung documents codes like -dE- and -dC- for partition switch faults and SE for a shorted key. Temperature sensor problems show up as abnormal oven behavior or sensor-related codes when resistance drifts out of the normal 1 kΩ range at room temperature. Loose harness connections at the control board or sensor also cause intermittent faults. Always verify the sensor and wiring before replacing the main board.
Most Common Problems on This Model
- Oven and cooktop will not heat but display is on Demo mode is enabled and must be turned off through the control panel settings menu to restore heating function.
- Oven temperature too high, too low, or erratic baking Oven temperature sensor has drifted or failed and should read about 1 kΩ at room temperature when tested with a multimeter.
- Information code appears on display and oven stops Many codes clear with a control reset by turning off the circuit breaker for 60 seconds and then restoring power.
- -dE- or -dC- partition error code displayed Partition is not installed correctly or something is pressing the partition switch, requiring mechanical adjustment or switch replacement.
- SE shorted key error code on display Membrane keypad has a stuck or shorted button and the keypad control assembly needs replacement.
- Intermittent codes or oven shuts off randomly Loose wiring harness or poor connector contact at the control board or sensor requires inspection and reseating of all connectors.
- Codes persist after sensor and wiring test good Main control board has failed and requires replacement after verifying sensor resistance and all harness connections.
Parts That Commonly Fail
| Part | Notes |
|---|---|
| Oven temperature sensor | Amazon | Should measure approximately 1 kΩ at room temperature. Open or out-of-range readings indicate failure. |
| Main control board (oven electronic control) | Amazon | Replace only after sensor and wiring verify good. Controls oven heating and displays information codes. |
| Membrane keypad / control panel assembly | Amazon | Fails with stuck or shorted keys, triggering SE error code. Includes touchpad and overlay. |
| Partition switch (Flex Duo models) | Amazon | Triggers -dE- or -dC- codes when switch is faulty or partition is not seated properly. |

When to Call a Pro
Call a pro for any repair that involves gas line work, such as replacing gas valves, disconnecting the range from the gas supply, or diagnosing burner ignition problems. Licensed gas fitters are required by code in most areas for those tasks. Also call a technician if you are not comfortable working with 240V power, testing components with a multimeter, or replacing the main control board. If codes persist after a reset and you cannot verify sensor resistance or harness integrity, a qualified appliance tech can diagnose the control system safely and correctly. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
