Question about Coleman Mach 15 Air Conditioner
Is your Air Conditioner run with a wall mounted thermostat or the ceiling pack controls? If it is the ceiling pack controls, then your selector switch has gone bad and needs to be replaced. This is located in the ceiling pack itself and is relatively easy to do. You can easily test it with an Ohmmeter, going through these steps:
To check the selector switch, remove wires from the terminals
and rotate the switch to the proper position and read
continuity as follows:
Terminals Switch Position
L-1-3 Lo Heat
L-1 Lo Fan
L-2 Hi Fan
L-1-4 Lo Cool
L-2-4 Hi Cool
* If you do not wish to remove the wires from each terminal,
disconnect the 9 pin plug from the a/c unit.
Hope this helps,
