Narrative:

An evening call was received for an aircraft from maintenance control; flight crew reported '2-left arming levers get stuck when arming'. I was assigned to the gate call and I went to the aircraft. When I arrived at the aircraft there was nobody onboard so I referred to the logbook to see the exact discrepancy reported which was '2-left arming levers get stuck when arming' I approached the L-2 door and started to inspect the door mechanisms. I opened the door and noticed that the arming levers where indeed getting stuck; both while opening and closing; arming and disarming the L-2 door. I inspected the mechanisms inside the door lining and found no visible indication of what could've been causing the door handles to be getting stuck. I also visibly checked the girt bar engagement to the floor and all was operating normally. After closing the door one more time I 'armed' the door; then 'disarmed' the door with the handles being rough to disarm. While lifting the main handle to open the door I saw the escape slide starting to deploy and I let go of the door and the slide deployed completely. After the slide deployed I verified again; the position of the disarming levers and they were in the 'disarmed' position. Door might of been misrigged or worn down; causing handles to be getting stuck and mechanism within the door not disengaging properly. Evening.
