Arrived on site and checked in with third party and manager on duty. Went into the back inventory area to check supply temperature, found that the unit that controls the vav was not operating. Went to security for roof access and proceeded to the unit that controls the VAV. Unit was in “stop” mode. Put unit to Auto and the system came online. Went back to the store and felt air from the unit but not downstream of the vav. Upon closer inspection of vav damper motor, found the shaft was binding up and not allowing the damper to open. Removed motor from shaft and reassembled. The damper is now open and cooling the back office and fitting room. Checked out with MOD, security and third party. Close-out: 1349934 Jennifer D
