GE Appliances dryer E3 to E6: thermistor error

E3 to E6 means: Thermistor (temperature sensor) error, inlet or outlet.

Short answer. One of the two temperature sensors (inlet on the heater housing, outlet on the blower housing) is reading open or short. Loose wiring is common; the thermistor itself is cheap. On some models E6 is instead an airflow restriction.

How to fix E3 to E6

  1. Unplug for 30 seconds and restart.
  2. Clean the lint filter and check the vent is not blocked (an overheated dryer can trip these).
  3. Unplug, open the panel, and check the thermistor plugs and harness for loose or corroded contacts.
  4. Meter the thermistor (about 10k ohms at room temperature); replace if open.

When to stop and call a repairer

Unplug before opening the cabinet.

What it costs

Parts: Thermistor $10 to $25.

Service: A home visit from an appliance technician runs $120 to $250 for diagnosis plus the part. Boards are the expensive part; sensors and switches are cheap.

Worth repairing? Yes.

How to check the error log

On newer GE dryers (GTD/GFD 2016 on), with the dryer off, press and hold the Signal and Temp buttons for 5 seconds to enter service mode; the last stored error shows. On SmartHQ models the app lists stored codes. Unplugging for 5 minutes resets the board.

Clear the log after a repair so you can tell whether the fault has really gone.
