GE dryer displays E5 and will not start or stops mid-cycle.

Safety first: Unplug the dryer or turn off the breaker. Gas dryers: shut off gas supply.

Inspect exhaust thermistor and airflow:

• Pull the dryer away from the wall and disconnect the vent hose.
• Check the vent hose and wall duct for heavy lint buildup or crushed sections; clean or replace as needed.
• Remove the rear panel to access the exhaust duct and thermistor (near the blower outlet).
• Disconnect the thermistor and test resistance at room temperature; compare to GE specifications. Replace if open, shorted, or out of range.
• Inspect wiring from thermistor to control board for damage or loose connections.
• Clean lint from the blower housing and internal ducts.
• Reassemble, reconnect vent (ensuring it is not kinked), restore power, and test.

If E5 returns: The main control board temperature circuit may be defective and should be replaced by a professional.
