System timed out after sensing temperature fault
Bad APCI heater/sensor assembly
Bad AC board
Power cycle the instrument and monitor APCI heater read back and set point. Set the Vaporizer to 300 °C. If the heater is not working, the actual value for the Vaporizer (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.
