Samsung NX58K9500WG/AA-00 gas slide-in range Parts

If your Samsung NX58K9500WG gas slide-in range has surface burners that work but the oven will not heat, the most common cause is a failed oven ignition system (especially a weak igniter). Less commonly, the bake burner, gas valve, temperature sensor, or control board circuit is preventing the oven from lighting.

Quick checks we recommend first

• Confirm the oven is set to Bake (not Delay Start, Sabbath, or Keep Warm) and the temperature is above 200°F.
• Listen for a click and watch for an orange glow from the igniter after starting Bake.
• If the igniter glows but the burner never lights within about 30 to 90 seconds, the igniter is typically too weak.
• If there is no glow and no clicking, check power to the range (the oven ignition needs electricity even though it is gas).
• If the oven lights sometimes but temperature swings widely, the sensor can be a factor.

For model-specific operating steps and settings, follow the NX58K9500WG owner's manual.

Most likely causes (and what you will notice)

What you observe	Most likely issue	Common fix
No igniter glow	Igniter circuit problem, wiring, control issue	Inspect connections; test components
Igniter glows, no flame	Weak igniter	Replace igniter
Flame starts then goes out	Gas valve or flame sensing/ignition issue	Diagnose valve and ignition
Oven heats but is inaccurate	Temperature sensor out of range	Replace sensor

Parts that commonly solve “stove works, oven won’t heat”

• Samsung range bake igniter DG94-01012A (most common for no-heat)
• Samsung range oven burner igniter DG94-00520A (ignition issues depending on configuration)
• Samsung range bake burner DG62-00066A (burner won’t carry flame or is damaged)
• Wall oven gas valve DG94-00449A (valve not opening for bake)
• Samsung range oven temperature sensor DG32-00002B (temperature problems or intermittent heating)

Why it matters

When the cooktop works, it proves you have gas supply, but the oven still needs a strong igniter and proper control signals to open the oven gas valve. A weak igniter is the top reason the oven never lights even though everything else seems normal.

For the Samsung NX58K9500WG gas slide-in range, the most reliable reset is a hard power reset: turn the range off, switch the circuit breaker off for 1 to 5 minutes, then restore power and set the clock. This clears many control glitches and error beeps.

Reset options (what to try first)

• Hard reset (recommended): breaker OFF 1 to 5 minutes, then ON.
• Cancel/Stop reset: press CANCEL/OFF once to stop a cycle and clear the display.
• Control Lock check: press and hold the Lock or Control Lock key (often 3 seconds) to toggle it off.
• Clock reset: after power returns, set the clock; some functions will not run until time is set.
• Wi-Fi/app features: if your range has smart features, power cycling the range can also reinitialize connectivity.

Step-by-step: hard reset (breaker reset)

1. Turn all surface burners and the oven OFF.
2. Flip the range circuit breaker OFF.
3. Wait 1 to 5 minutes.
4. Flip the breaker ON.
5. Set the clock and try BAKE again.

If the oven still will not heat after a reset

A reset fixes control logic issues, but it will not fix a failed heating component. Use this quick check list:

• Confirm the display responds and you can start a bake cycle.
• Listen for the oven ignition sequence (clicking, then burner ignition).
• If the oven will not ignite or takes a long time to light, inspect the igniter circuit.
• If temperature is inaccurate, the sensor circuit is a common cause.

Symptom after reset	Most common area to check	Example part for this model
Oven will not ignite	Bake igniter / ignition circuit	Samsung range bake igniter DG94-01012A
Oven temperature is off	Oven temperature sensor	Samsung range oven temperature sensor DG32-00002B
Display works but oven acts erratic	Control / wiring connections	Check wiring and connectors per NX58K9500WG manual

Why it matters

Resetting restores normal operation after a power surge, stuck key input, or control lock activation. If the problem returns quickly, focusing on the igniter, sensor, or wiring prevents repeated no-heat failures and inconsistent baking.

On a Samsung gas slide-in range like model NX58K9500WG, a “bad thermostat” symptom is usually the oven temperature being consistently too hot or too cool compared to the set point. The quickest check is comparing the oven’s set temperature to an accurate oven thermometer reading after a full preheat and stabilize period; then decide whether calibration or a sensor/ignition repair makes more sense.

Quick test: verify actual oven temperature

1. Place an oven-safe thermometer in the center of the middle rack.
2. Set Bake to 350°F.
3. Let the oven preheat, then allow 20 to 30 minutes for the temperature to stabilize.
4. Record the thermometer reading.
5. Repeat at two more set points (for example 300°F and 400°F) to see if the error is consistent.

What results mean (simple guide)

What you see	Most likely cause	What to do next
Off by 10 to 25°F but consistent	Normal variation or calibration issue	Check calibration steps in the NX58K9500WG owner's manual
Off by 30°F+ at multiple temps	Temperature sensing problem	Consider replacing the oven temperature sensor Samsung range oven temperature sensor DG32-00002B
Temperature swings wildly, long preheat, weak heat	Ignition or burner issue (common on gas ovens)	Inspect igniter and burner; consider Samsung range bake igniter DG94-01012A or burner service

Other signs the “thermostat” function is failing

• Food consistently undercooks or overcooks at the same setting.
• Preheat takes much longer than normal.
• Oven struggles to recover temperature after opening the door.
• You smell unburned gas briefly or the burner lights late (igniter-related).
• Error codes or beeping tied to temperature control (often sensor or control board related).

Safety and accuracy tips

• Use a known-good oven thermometer; cheap or damaged thermometers can be off.
• Keep the thermometer away from the oven walls and door glass.
• Avoid opening the door during the stabilize period.
• If you suspect a gas ignition problem, stop using the oven and have it serviced.

Why it matters

Accurate temperature control protects baking results and prevents overheating. On many Samsung ranges, the temperature sensor and the bake ignition system do the real “thermostat” work, so testing helps you replace the right part the first time.
