      If your GE Medical Equipment displays a global alarm that continues to be lit, it is likely due to a CPU failure. To resolve this, replace the PWA with FRU 2043951-001 for warmers with a halogen lamp and transformer or replace the PWA with FRU 2062277-001 for warmers with SMPS and LED observation lamps.
