Every 15 minutes, the system enables the temperature control and reevaluates the error condition. If
the problem that caused the condition has been corrected, the system clears the D38 condition
automatically. If the problem has not been corrected, it displays the D38 condition code again.
Solutions
Check that the measurement module door is closed tightly.
Check that the sample ground/temperature sensor is installed correctly. If the
sensor is not correctly installed, remove and install it as described in Cleaning
the Sample Ground/Temperature Sensor in Section 3.
Check that the location of the system meets the specifications for ambient
operating temperatures as described in Appendix H, Installation.
Check the air filter to ensure that the air vent is not obstructed. If the air filter is
obstructed or dirty, replace the air filter as described in Replacing the Air Filter
in Section 3.
Check that the fan is operating.
Perform the Temperature/pAtm Test as described in Temperature/pAtm Test,
