Error Code tE1

Thermistor fault — blower housing thermistor open or shorted

Also displayed as: tE1

How to Fix

1. 1

   Turn power off and discharge capacitors by contacting metal plug of power cord with ground.

2. 2

   Remove connector NA6 from the controller.

3. 3

   Short Pin 2 (Blue Wire) and Pin 5 (Orange Wire) on the NA6 connector to the controller.

4. 4

   If the error clears, check that the control connector and 6-pin harness are properly connected; replace controller if defective.

5. 5

   If error does not clear, measure resistance between thermistor assembly connector terminals after separating harness.

6. 6

   Compare measured resistance against Table 1: at 50°F (10°C) expect 18.0kΩ, 70°F (27°C) = 9.3kΩ, 100°F (38°C) = 6.2kΩ, 120°F (49°C) = 4.3kΩ, 140°F (60°C) = 3.0kΩ.

7. 7

   If resistance is out of range, replace the thermistor assembly.

8. 8

   If resistance is in range, inspect and repair harness-linking connector.

9. 9

   tE1 error is displayed during the drying cycle or in test mode.
