GE Dryer E03 Error: Outlet thermistor shorted
This guide covers GE dryer E03 error in detail to help you diagnose and resolve the issue. What Does GE Dryer Error Code E03 Mean? Error code E03 indicates that the outlet thermistor — mounted on the blower housing at the rear of the dryer drum — has shorted and is returning an out-of-range temperature […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. With E03 active, the dryer cannot regulate exhaust temperature. Continuing to run risks damaging the motor and creating a fire hazard from trapped heat.
Can I reset the code?
Yes. A hard reset (unplug 30 s) clears the code temporarily. If E03 returns on the very next cycle, the outlet thermistor itself has failed and must be replaced.
When to stop immediately?
Stop if you notice: Exhaust duct is fully clear yet E03 returns on every cycle, Burning or melting smell from behind the dryer.
Symptoms You May Notice
E03 on display; dryer tumbles without heat
The drum motor runs normally and the display shows the cycle countdown, but the heating element remains off, leaving laundry cool and damp at cycle end.
Dryer shuts down mid-cycle
The dryer may run for a few minutes before E03 appears and the cycle halts, particularly if the fault develops only after the thermistor warms up.
Automatic cycles run indefinitely
Sensor-dry cycles use outlet temperature to decide when clothes are dry. A shorted sensor reporting false high temps can cause the cycle to terminate prematurely or run until the timer expires.
Error resets but immediately returns
Unplugging clears the fault flag, but E03 reappears within the first 60 seconds of the next cycle because the thermistor short is permanent, not transient.
Possible Causes
Defective outlet thermistor
The thermistor on the blower housing has internally shorted and must be replaced. It is the most common cause of E03 on GFD and GTD models.
DIY PossibleRestricted exhaust duct causing overheating
A heavily blocked duct traps hot air at the outlet sensor, which can eventually damage the thermistor and produce intermittent E03 faults.
DIY PossibleBroken wiring harness connector
The connector plug between the thermistor and the wiring harness can crack or corrode, creating a short-circuit path that mimics a failed sensor.
DIY PossibleSafe Checks You Can Do
-
1
Clean the exhaust duct system
Disconnect the flexible duct from the back of the dryer and from the exterior wall cap. Use a dryer duct cleaning brush or vacuum to remove lint accumulation throughout the full duct length.
GE recommends cleaning the exhaust duct at least once per year. A blocked duct is the leading cause of thermistor damage on GTD and GFD dryers.

2
Reset the dryer
After clearing the duct, unplug the dryer for 30 seconds, then restart with a timed dry cycle. Watch to see if E03 appears immediately or after a few minutes.
Immediate reappearance points to a physically failed thermistor; delayed appearance after several minutes suggests an airflow problem is causing heat buildup.

Check exterior vent flap
Go outside and confirm the exterior wall vent flap opens freely when the dryer is running and is not obstructed by a screen, lint, or bird nesting material.
A blocked exterior vent is a fire hazard and the single most common cause of recurring thermistor errors on all GE dryer models.
When to Call a Professional
Contact a qualified technician if:
- E03 persists after duct cleaning and thermistor replacement
- Outlet thermistor measures near-zero ohms with dryer unplugged
