Outside air damper: no obstructions

Yes Work Order Closed by Building Maintenance

OAHU-2 and OAHU-4- A portion of the outside air dampers appeared to be 100% closed. These are dedicated outside air units and should be capable of bringing in100% outside air all the time while running.
AHU-3 and AHU-5 - Outside air dampers (OADs) appeared to be closed. AHU-6- OADs are open but only slightly.
There seems to be a lot of inconsistency on the position of the outside air dampers. Some are completely closed while others are more open. Today's outdoor weather conditions are ideal for the economizer mode, meaning the OADs should be open more than the minimum position up to 100%.
