I have a Coleman Mach #9330F715 in a StarCraft Launch 16RB. When we turn on air, it runs constantly, but gets cold. Only way to turn down how cold it gets is by the blue/red knob. What should we do?

Time for a spring cleanning,, especially the drainnage system, filter,, front cooling coils-and the drain line! thank you-very-much!

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the ac........plus your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $130....now you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know [email protected]

SOURCE: Coleman unit, no heat or air, only fan runs.

check for wiring & compresor

SOURCE: Recycling to soon?

sounds like the unit is low on freon. it will need to be serviced so the leak can be fixed then recharged.

SOURCE: I have a Mach III. Unit blows hot air and bogs down when cooling.

probably (90 %) the compressor's bad, depnding on the repair cost you probbly want to just get another AC unit
