Over-temperature Condition (Control Board Thermistor Fault, Adv. Code 3)

What does 19 mean?

This fault indicates a problem with the control board temperature sensor (thermistor) or its connection. The drive cannot accurately monitor the control board temperature, which could lead to undetected overheating and damage to critical control components. This compromises the drive's ability to protect itself.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If connections are good and the thermistor tests faulty, it may require replacement. Consult the factory for replacement parts.

2. 4

   If the issue persists after checking connections or replacing the sensor, consult the factory for further diagnosis of the control board.
