They replaced the failed relay coil, and the dryw cli Door and equipment drain system was thereby reestablished, and the LCO exited.

This failed relay (a CR120A model) had been in service, in the normally.cnergized state, for approximately 23 years, it is believed that the failure is age related, and that degradation had escalated rapidly since the previous thermography inspection . To preclude further system interruptions, coil replacement of the remaining 16 normally energized CR120A relay coils is scheduled to be accomplished by st rtup from i
