What to do if one or more valves fail to open (trip) on Woodward Control Unit?
- KKristen LittleAug 5, 2025
If one or more valves fail to open (trip) on the Woodward Control Unit, several issues could be the cause. First, check for valve seizure or excessive oil contamination. Perform a proof test at the recommended interval and replace and filter the oil, flushing clean oil through the valve. Second, ensure all speed sensors and the logic solver are functioning correctly, and that all wiring connections are correct. Third, verify that the hydraulic fluid meets the recommended filtration and ISO cleanliness levels.
