GE Dryer E003 Error Code
Exhaust thermistor open
What this error means
E003 indicates open exhaust temperature sensor circuit.
How E003 is detected
When E003 appears on a GE dryer, the control board has confirmed that water did not leave the machine within the programmed drain window. On GE GTD72EBSNWS, GE GFD85ESPNRS, 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 E003 calls are resolved without parts: reseat thermistor. 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 E003 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
- Loose plug
- Broken wire
- Open sensor
- Lint on connector
Step-by-step fixes
- 1Reseat thermistor
- 2Vacuum connector area
- 3Measure ohms at room temp
- 4Run low heat test
When to call a technician
Open sensor with good wiring needs replacement.
Affected models
- GE GTD72EBSNWS
- GE GFD85ESPNRS
- GE GTD42GASJWW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dryers to prevent E003 from lint and food debris buildup.
- Record when E003 appears in the cycle and whether it clears after a 60-second power reset on your GE dryer—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E003; GE uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E003; reversed plugs on pumps and valves cause immediate repeat faults.
