I took a call from Aircraft X telling me that 'No.1 TR failed to open on landing '; which I had the Captain document in the log book. I then called ZZZ MX to alert them of this issue along with the fact that the No. TR was MEL'd and RIC was the ZZZ1 base it was at prior to this first flight of the day and to make certain the MEL deactivation was correctly performed. A call came in from ZZZ informing me that the wrong ICU was inhibited. They remedied the issue and the aircraft was returned to service. This was also an issue one day before; I was not working then; and the same discovery was made and remedied. I am guessing the closeness of the ICU 1 and ICU 2 is confusing to some. Follow Manual procedures and take close look at work after doing it while comparing it to manual pics.
Maintenance Technician found incorrect maintenance accomplished on aircraft thrust reverser.
