GE Dryer E05 Error: Outlet thermistor open circuit
This guide covers GE dryer E05 error in detail to help you diagnose and resolve the issue. What Does GE Dryer Error Code E05 Mean? Error code E05 means the control board detects an open circuit on the outlet thermistor — the temperature sensor mounted on the blower housing. Unlike E03 (short circuit), an open […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. An open thermistor circuit means the control board has no exhaust temperature data. Operating the dryer risks uncontrolled heating if the circuit intermittently closes.
Can I reset the code?
Yes. A reset clears the fault flag but E05 will return immediately on the next cycle if the thermistor is open. Replace the sensor for a permanent fix.
When to stop immediately?
Stop if you notice: E05 returns on every cycle after resetting, Dryer runs with no heat whatsoever.
Symptoms You May Notice
E05 at startup; no heat produced
The dryer displays E05 and the heating element never activates. The drum tumbles, air circulates, but clothes remain cold and wet throughout the cycle.
Sensor-dry cycles do not complete
Without a working outlet thermistor, the automatic moisture-sensing logic has no temperature reference and the cycle may abort or time out without drying.
Code appears intermittently
A cracked connector or loose wire can cause E05 to appear only after vibration during a cycle, making it seem like a random fault.
Dryer runs cold even after reset
Each time power is restored and a cycle starts, E05 returns within seconds because the open-circuit condition is persistent, not transient.
Possible Causes
Open-circuit outlet thermistor
The thermistor's internal element has broken, creating infinite resistance. The control board detects no signal and faults. Replace the thermistor.
DIY PossibleLoose or disconnected wiring harness
The connector at the thermistor or at the control board may have vibrated loose, breaking the circuit. Check both ends of the thermistor wiring before ordering a new part.
DIY PossibleBroken wire in harness
A wire in the thermistor harness can fatigue and break internally while still appearing intact externally, particularly where the harness bends near the blower housing.
Requires ProfessionalSafe Checks You Can Do
-
1
Hard-reset the dryer
Unplug for 30 seconds and restore power. Start a timed dry cycle and note whether E05 appears instantly (< 30 s) or after a few minutes of running.
Instant recurrence confirms an open circuit that will not self-repair; a delayed appearance suggests a vibration-sensitive loose connector.

2
Clean the lint screen and duct
Remove the lint screen and clean it thoroughly. Inspect the exhaust duct for blockages. A clean exhaust path rules out heat-damage to the thermistor as the cause.
Always rule out airflow issues before replacing the thermistor, especially if the dryer is more than 5 years old.

3
Check the circuit breaker (electric models)
Confirm both legs of the 240 V supply are active by fully toggling the dryer breaker off and back on. A partial power loss can mimic a thermistor open-circuit fault.
If one leg of the 240 V supply is missing, only the motor will run — no heat — which looks identical to an E05 fault.
When to Call a Professional
Contact a qualified technician if:
- E05 persists after replacing the outlet thermistor
- Visible wire damage or burn marks on the blower housing harness
