Poor air circulation in your unit can be caused by the motor not reaching full speed, a loose fan blade, the device under test (DUT) is too large, or the DUT is obstructing the airflow.
Check out these possible causes and solutions:
|The motor is attempting to run on low voltage.||
|The shaft is dragging on insulation in the test chamber wall.||
|The fan blade is hitting.||
|The area is too small for the application or DUT is too large or is improperly inserted.||
