Error Code tE2

Temperature sensor (thermistor) failure — shorted circuit

Also displayed as: tE2

How to Fix

1. 1

   Power off the dryer immediately.

2. 2

   Enter diagnostic mode: press Power then immediately press Temp and Time.

3. 3

   Note tE2 displayed during diagnostic confirms thermistor shorted.

4. 4

   Disconnect power and discharge capacitors.

5. 5

   Remove NA6 connector from the main PCB.

6. 6

   Measure resistance between Pin 2 (Blue) and Pin 4 (Orange) without shorting.

7. 7

   If resistance reads near 0 Ω (shorted), the thermistor or wiring harness has a short to ground or between conductors.

8. 8

   Measure resistance between Pin 2 (GN/ground pin) of NA6 and chassis ground — should be less than 1 Ω if there is a wiring short to ground.

9. 9

   Separate the harness from the thermistor assembly connector and remeasure.

10. 10

    If still shorted, replace the thermistor assembly.

11. 11

    If now open, inspect harness for wires contacting chassis or each other.

12. 12

    Repair or replace harness as needed.

13. 13

    If fault persists with a confirmed good thermistor and harness, replace the main PCB.

14. 14

    Restore power and confirm no tE2 recurrence.
