## Discrepancy

AIRCRAFT WAS GROUNDED: PILOT REPORTS AT CRUISE, R PACK RESET SW INOP & PACK OFF CAME ON. QRH PROCEDURE FOLLOWED AND RESET, HOWEVER  LIGHTS CAME ON AGAIN - 10 MIN LATER. PACK TURNED OFF AND DESCENT FROM FL380 TO FL320 ALLOWED L PACK TO HANDLE PRESSURIZATION AND TEMPERATURE. MAINTENANCE REMOVED & REPLACED LOW LIMIT VALVE IAW AMM 21-51-11. OPS CHECK NORMAL.
