Error Code tE1

Outlet thermistor open or shorted (blower housing thermistor #1)

Also displayed as: tE1

How to Fix

1. 1

   Turn off the dryer.

2. 2

   Enter diagnostic test mode (press POWER while pressing MORE TIME and LESS TIME simultaneously) to confirm tE1 is displayed.

3. 3

   Unplug the dryer and discharge voltage (contact metal plug of power cord with ground).

4. 4

   Disconnect the NA6 connector (6-pin) from the main PCB.

5. 5

   Measure resistance between NA6-1 (YL) and NA6-4 (BL).

6. 6

   Compare reading to thermistor resistance table: at 50°F=18.0 kΩ, 60°F=14.2 kΩ, 70°F=9.3 kΩ, 80°F=11.7 kΩ, 90°F=7.7 kΩ, 100°F=6.2 kΩ, 110°F=5.2 kΩ, 120°F=4.3 kΩ, 130°F=2.9 kΩ, 140°F=3.0 kΩ, 150°F=2.5 kΩ, 160°F=2.2 kΩ.

7. 7

   If PCB connector resistance matches chart but error persists: replace the main PCB.

8. 8

   If PCB connector resistance does not match: separate harness from thermistor assembly connector and measure resistance directly at thermistor terminals.

9. 9

   If thermistor resistance is out of range: replace the thermistor.

10. 10

    If thermistor resistance is in range: inspect and reseat harness-linking connector between thermistor and main PCB.
