Coleman-Mach 10 45204/45254 15,000 BTU Cooling A/C Parts
These Mach 10 cooling-unit references cover 45204-8762, 45204-8792, 45254-8762 and 45254-8792. Their original parts tables match except for the shroud finish. The parts list is kept separate from the 45004/45054 heat-pump family because its refrigeration and electrical components differ.
Before choosing a service part: These older diagrams identify the original components. Match the full unit model and serial number, and confirm current replacement numbers with Coleman-Mach before ordering.
