Description
Coleman-Mach 9430-754 is a cool-only multi-zone control box designed for the Coleman-Mach 9420A330 touchscreen thermostat. This exact part number is listed in Airxcel's 2025 thermostat and control catalog. It is a control component, not merely a generic rooftop air-conditioner repair part.
Part specifications
- Manufacturer: Coleman-Mach / Airxcel
- Part number: 9430-754
- Component type: Digital touchscreen-platform zone control box
- Control function: Cooling only
- Thermostat application: 9420A330 multi-zone wall touchscreen (sold separately)
Compatibility guidance
The 9420A330 touchscreen uses its own system of control boxes: 9430-754 for cooling only, 9430-758 for cool/heat ready and 9630-758 for heat-pump/heat-ready operation. These are not equivalent to the similarly numbered legacy 9-series 9430A751, 9430A755 or 9630A751 products.
Check the existing thermostat and original control-box label, rooftop model and wiring harness. The control box must be selected for the installed cooling/heating configuration. The wall thermostat and rooftop air conditioner are not included. Follow the relevant manufacturer service instructions.
