Coleman-Mach J-Box Assembly Complete | RV Air Conditioner Replacement Part

The J-box on a Coleman-Mach rooftop air conditioner is the electrical junction point that ties the unit's wiring together. When it cracks, corrodes, or a connection inside fails, this complete assembly replaces the whole unit rather than requiring piecemeal repair.

It's sized to match Coleman-Mach's factory J-box, so it fits into your existing AC housing without modification.

• Complete J-box assembly, not individual components, for a full replacement
• Designed for Coleman-Mach RV air conditioner and heat pump systems
• Compact housing simplifies wiring reconnection during install
• Lightweight part that's easy to handle during service

Confirm compatibility with your specific Coleman-Mach model before ordering.
