the next time it`s windy go outside and push the opener[s] against the frame, if the humming stops then it`s just an adjustment problem. the locks [cams] that engage the opener into the keeps can be adjusted by use of an allen key. adjusting the cams pulls the opener tighter against the rubber seal. i`m summising that this is creating the humming sound but also check the silicone sealing around the frame itself
