Samsung Oven E-17 Error Code
Main temperature sensor open circuit
What this error means
E-17 (E-21/E-27 family) is an open Oven Temperature Sensor error—the main RTD or its wiring reads over 2950 Ω, so the board cannot detect cavity temperature and disables heat.
How E-17 is detected
When E-17 appears on a Samsung oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung NE59M6850SS, Samsung NE58F9710WS, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most E-17 calls are resolved without parts: breaker off before accessing sensor wires at the rear. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If E-17 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Sensor connector loose at the main PCB
- Broken sensor wire inside cavity insulation
- RTD probe internally open after years of heat cycles
- Previous repair left the sensor unplugged
Step-by-step fixes
- 1Breaker off before accessing sensor wires at the rear
- 2Disconnect sensor and measure ohms—expect ~1080 Ω at room temp, not open
- 3Reseat the plug at the board if ohms were borderline
- 4Retry preheat after reseat if reading was intermittent
When to call a technician
Open reading with intact harness requires oven temperature sensor probe replacement from the cavity wall.
Affected models
- Samsung NE59M6850SS
- Samsung NE58F9710WS
- Samsung NE63A6511SS
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use ovens to prevent E-17 from lint and food debris buildup.
- Record when E-17 appears in the cycle and whether it clears after a 60-second power reset on your Samsung oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E-17; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E-17; reversed plugs on pumps and valves cause immediate repeat faults.
