## Discrepancy

CREW REPORTED THAT DOOR SEAL CAUTION LIGHT DOES NOT COME ON WHEN SEAL DEFLATED.  FOUND DOOR SEAL PRESSURE SWITCH STUCK OPEN.  SUSPECT CAUSE IS CORROSION/CONTAMINATION, AND/OR POSITION OF SWITCH.  SUBMITTER SUGGESTS A MORE RESISTENT SWITCH OR A BETTER POSITION TO MINIMIZE CONTAMINATION.
