I got a gate call for an overhead flap/slat position light (amber) taking a few seconds to go out before the others. I talked to the Captain and he told me the #3 Krueger flap light was slow to extinguish. I explained that I did not think there was any relief for a Krueger flap problem. I cleared the [area around the] airplane and set the flaps down. I visually inspected the flap; position sensors; targets; and a general visual to make sure there was no damage. I retracted the flaps and it took about 2-3 seconds longer for the light to go out. I called Maintenance Control and explained what I did and another Controller got on the phone and said he had the MEL ready to go. Apparently; unknown to me; the pilot called Maintenance Control and I am not sure what was discussed. Since Maintenance Control had a MEL ready; I assigned the MEL to the aircraft. The MEL was pulled up and I followed the MEL procedures. I assumed the MEL list must have changed since the MEL was being assigned for a Krueger Flap. I should have reviewed all the documents required to verify the job was done correctly; and speak directly to Maintenance Control to coordinate our understanding of the corrective action. Do not assume the procedures have changed and double check my work.
A Maintenance Technician applied the MEL called for by Maintenance Control without verifying that it was the proper reference.
