When your Coleman Mach rooftop air conditioner is blowing weak or not moving air at all, the blower motor is the first place to look. This OEM-specification 2-speed replacement motor is engineered to restore full heating and cooling airflow in Mach 1 PS, Mach 3 PS, and 48xxx series units -- no modifications, no adapters, no guesswork.
The 1468-3489 blower motor is a genuine Coleman Mach replacement part designed for the specific fan deck and wiring configuration found in the Mach 1 PS, Mach 3 PS, and 48xxx rooftop air conditioner series. These units are among the most common factory-installed AC systems on travel trailers and fifth wheels, and worn or failed blower motors are one of the leading causes of reduced cooling performance on aging units.
This motor drives the evaporator and condenser blower assemblies at two distinct speeds -- low for quiet circulation and high for maximum cooling or heating output. Both speed taps are present on the motor, matching the OEM wiring harness connector layout found in compatible units.
Separate low and high speed taps match OEM wiring. Both thermostat speed settings function after installation.
Matches the original mounting bracket and shaft configuration in Mach 1 PS, Mach 3 PS, and 48xxx series air conditioners.
Worn motors cause reduced BTU delivery and warm spots. A new motor brings the blower back to rated CFM output.
Sourced from the Coleman Mach parts program. Part number 1468-3489, vendor code CMN1468-3489, UPC 755790408856.
This motor is designed for use in the following Coleman Mach rooftop unit families:
If you are unsure whether this motor fits your specific unit, locate the model number label on the rooftop shroud or on the inside of the ceiling assembly and cross-reference it against the 48xxx series range or confirm your unit is a Mach 1 PS or Mach 3 PS.
Replacing the blower motor in a Coleman Mach unit typically requires removing the inside ceiling assembly (air distribution box) to access the fan deck. Disconnect shore power or battery before beginning any work. The motor mounts to the fan deck bracket using the original hardware. Reconnect the wiring harness to the matching speed taps -- polarity and connector position follow the same layout as the original motor. Reinstall the blower wheel on the motor shaft before reassembly.
Note: The blower wheel (squirrel cage) is NOT included with this motor. Reuse your existing wheel if it is undamaged, or order the appropriate Coleman Mach replacement wheel separately.
