When inspecting the PCMS Discharge Opening, what should you look for?

• A. Dirt or moisture
• B. Moisture only
• C. Color changes
• D. Cracks

Answer: (A)

Inspecting the discharge opening is about catching signs of contamination and ingress that could affect performance or safety. Dirt or moisture around the PCMS discharge opening is the clearest indicator that outside material or water has entered the path, pointing to compromised seals, gaskets, or venting. Dirt shows particulate ingress, while moisture signals liquid intrusion, and together they reveal a breach that needs attention. Moisture alone could come from humidity and might not reveal solid contamination; color changes or cracks indicate other issues (aging, corrosion, or physical damage) but don’t directly confirm current ingress at the opening. If you notice dirt or moisture, prioritize inspecting and addressing seals and the discharge path to prevent potential malfunctions.
