Error Code tE1

Thermistor of blower housing open or shorted

Also displayed as: tE1

How to Fix

1. 1

   Enter diagnostic test mode: unit in standby, press Power then simultaneously press More Time and Less Time for 0.5 seconds.

2. 2

   If tE1 displays during diagnostics, disconnect power immediately.

3. 3

   Remove the NA6 connector from the controller.

4. 4

   Short the 6-pin NA6 connector Pin 4 (Blue Wire) and Pin 3 (Orange Wire) together with a metal jumper.

5. 5

   If the tE1/tE2 error clears after shorting, the wiring to the controller is intact — check that NA6 connector and the 6-pin connector are properly connected to the controller.

6. 6

   If error persists after shorting, reconnect connector and measure resistance between the thermistor terminals after disconnecting the thermistor harness.

7. 7

   Compare resistance to Table 1: at 50°F (10°C) expect 18.0 kΩ; at 70°F (21°C) expect 11.7 kΩ; at 80°F (27°C) expect 9.3 kΩ; at 90°F (32°C) expect 7.7 kΩ; at 100°F (38°C) expect 6.2 kΩ; at 110°F (43°C) expect 5.2 kΩ; at 120°F (49°C) expect 4.3 kΩ; at 130°F (54°C) expect 2.9 kΩ; at 140°F (60°C) expect 3.0 kΩ; at 150°F (66°C) expect 2.5 kΩ; at 160°F (71°C) expect 2.2 kΩ.

8. 8

   If resistance is outside range, replace the thermistor assembly.

9. 9

   If resistance is within range, check and re-seat the harness linking connector between thermistor and controller.

10. 10

    If all wiring checks pass and error persists, replace the main controller board.
