Possible causes to examine for this symptom
These causes are preliminary assessments. The same symptom can have different causes in different circuits.
A command is present; the load may exceed available force, or mechanical binding may exist.
How to check: Record command/fault indicators and the direction that stops. A qualified technician must verify coil supply, pilot conditions and work-line pressures.
Possible solution: Repair a confirmed electrical supply fault. If a pilot, valve or mechanical obstruction is confirmed, repair according to the circuit. Do not open a line until the load is safely secured.
