2.2 Drying gas heater controller cannot regulate the requested setting after a fixed amount of time. Power cycle is needed to clear condition.

Probable Causes

  • System timed out after sensing temperature fault

  • Bad drying gas heater/sensor assembly

  • Bad AC board

Suggested Actions

  • Power cycle the instrument and monitor the drying gas heater read back and set point. Set the Gas Temp to 300 °C. If the heater is not working, the actual value for the Gas Temp (in the Method > Source Section (LC/MS)) will not climb. It will remain between ambient and 150 °C. If the sensor is shorted, it may read much less than 10 °C.
