Operating arcade machines in high-humidity environments presents unique and persistent challenges for owners and technicians. The elevated moisture levels accelerate metal corrosion on critical components such as coin mechanisms, joystick assemblies, and internal wiring contacts. This corrosion leads to malfunctioning buttons, stuck coins, and eventual electrical failures. Printed Circuit Boards (PCBs) are particularly vulnerable as moisture promotes oxidation of delicate traces and connectors, causing short circuits and permanent damage to these expensive components.

Monitor displays suffer significantly in humid conditions, with moisture infiltrating screens causing clouding, distortion, and internal condensation that obstructs gameplay visibility. The constant moisture exposure also damages cosmetic elements, promoting mold growth on cabinet artwork, warping wooden panels, and peeling decorative laminates that diminish aesthetic appeal.

Environmental control becomes paramount in these conditions. While air conditioning helps, dedicated dehumidification systems are often necessary to maintain humidity below 50% RH - the recommended threshold for arcade operations. Regular maintenance intensity increases dramatically, requiring frequent cleaning of contacts with appropriate solvents, application of protective anti-corrosion sprays, and thorough inspections for early signs of moisture damage. Electrical safety concerns escalate as moisture increases conductivity risks, potentially creating hazardous situations for both machines and players. These combined factors significantly increase operational costs through more frequent parts replacement, higher energy consumption for environmental control, and increased technician labor hours.
