THIS FLC COULD NOT CTL THE RWY LIGHTS BY KEYING THE MIKE SO THE RWY LIGHTS REMAINED ON STEP 1. AFTER LNDG THE OPS PERSONNEL CONTACTED AN FSS SPECIALIST WHO CAME TO THE ARPT AND PUT THE RWY LIGHTS IN THE RADIO CTL MODE. AFTER THIS THE FLC WAS ABLE TO CTL THE RWY LIGHT INTENSITY.

Narrative

AT PM00 LCL BARROW FSS SHUTS DOWN FOR THE NIGHT AND REMOTES THEIR FREQS TO FAIRBANKS FSS. IN ADDITION; RWY LIGHTING IS SWITCHED FROM FSS CTL TO PLT CTLED. AT 10 NM FROM BARROW AT PM35 LCL WE ATTEMPTED TO TURN UP THE RWY AND APCH LIGHTS TO STEP 5 BY KEYING THE MIKE 7 TIMES. THE APCH LIGHTS ILLUMINATED BRIGHTLY; BUT THE RWY LIGHTS REMAINED ON STEP 1 (DIM). SUBSEQUENT TRIES AT STEPPING UP THE RWY LIGHTS WERE UNSUCCESSFUL. WE DETERMINED THE LIGHTS WERE ADEQUATE FOR A SAFE LNDG AND DID SO UNEVENTFULLY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE FLC WAS FLYING A B737-200 COMBI WHEN THEY ENCOUNTERED A PROB WITH THE RWY LIGHTS AT BARROW; ALASKA. THE APCH LIGHTS WOULD INCREASE IN INTENSITY; BUT THE RWY LIGHTS WOULD NOT. THE FLC LANDED WITH THE RWY LIGHTS AT STEP 1 AND INFORMED THEIR OPS PERSONNEL OF THE PROB. THE OPS PERSONNEL WERE ABLE TO LOCATE AN FSS EMPLOYEE AND HE CAME TO THE ARPT AND 'FLIPPED A SWITCH' AND THE FLC THEN HAD CTL OVER THE RWY LIGHTS AS WELL AS THE APCH LIGHTS.
