Dryer shows E1 and may not start or may stop shortly after starting.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open or shorted thermistor, Disconnected thermistor harness, Faulty main PCB sensor input

Safety first: Unplug dryer and shut off gas if applicable.

Steps:

Locate thermistor: Typically on the exhaust duct near the blower housing.
Check connection: Ensure the thermistor connector is firmly attached and wires are intact.
Test/replace: Measure resistance and compare to spec; replace if out of range or physically damaged.
Board check: If a new thermistor and good wiring still produce E1, the control board may be faulty.
