INTERMATIC k1121 Can the permantly closed Intermatic k1121 be diagnosed and reruned to on/off cycling?
The closed contacts would mean the relay is not energized or contacts welded closed. Given the relay is the only moving part, the chances are good the relay has failed. But probably a 50:50 chance other internal electronics. Possibly lightning strike which makes it not likely repairable.
Anything can be fixed but economics would prohibitive. So unless you looking for an electrical project... no.
Open it up and look for arcing and/or burnt components. Check relay coil for continuity. If relay coil is open, you might get lucky and merely replacing the relay will make it functional.
