Coleman Mach 6759-3251 Selector Switch, 6-Position
Coleman Mach 6759-3251 Selector Switch, 6-Position — Product description
This is the replacement 6-position selector switch for Coleman Mach ceiling assemblies on the 67, 8330, and 7330 models. One 2-speed knob runs your fan and swaps between low heat and cooling, so when the old switch gets gritty or a position quits, you drop this in and get full control back at the ceiling.
The selector switch is the knob you reach for every time you want heat, cool, or just some air moving through the rig. On Coleman Mach ceiling assemblies for the 67, 8330, and 7330 models, it's a 2-speed, 6-position rotary control, and after enough seasons of turning it, the contacts wear out or a position stops responding. This is the direct replacement, Coleman part 6759-3251, so you get all six positions back without swapping the whole ceiling assembly.
Here's what the six positions cover: Off, Low Heat, Low Fan, High Fan, Low Cool, and High Cool. One knob runs the fan speed and the mode. Turn it to Low Fan or High Fan when you just want circulation, drop it to Low Heat to take the chill off a cool morning, or roll it over to Low Cool and High Cool when the afternoon sun turns the coach into an oven. It's a simple mechanical control, and that's the point. Nothing to pair, nothing to program.
You'll want this switch when the old one feels gritty, sticks between detents, or a position quits working while the others still click. Those are classic signs of worn contacts inside the selector. Because it's the factory part number, it drops into the same spot in the ceiling-assembly control box and lands on the same terminals, so the wiring you already have carries straight over.
A few install notes from experience. Kill the power first, both the 120V AC to the air conditioner and the 12V DC at the thermostat side, before you open the control box. Label your wires or snap a quick photo as you pull them, since the terminals matter for getting heat and cool on the right positions. And take a second to confirm this is the analog selector-switch setup your unit uses. The 67, 8330, and 7330 ceiling assemblies with a manual 6-position knob are what this part serves.
It's a small part that makes a big difference in day-to-day comfort. When the switch is worn, the whole unit feels unreliable even when the compressor and fan motor are fine. Replace the switch and you're back to solid, predictable control at the ceiling.

Frequently asked questions
Which Coleman Mach units does this switch fit?
It's the replacement selector switch for Coleman Mach ceiling assemblies on the 67, 8330, and 7330 models that use a manual 6-position knob. Check that your unit has the analog rotary selector before ordering.
What are the six positions?
Off, Low Heat, Low Fan, High Fan, Low Cool, and High Cool. One knob handles both fan speed and mode.
Does this control heat as well as cool?
Yes. It has a Low Heat position for shoulder-season mornings, plus low and high fan and low and high cooling.
Is this the same as the factory switch?
It is. This is Coleman part number 6759-3251, the direct replacement for the original ceiling-assembly selector switch, so it lands on the same terminals as the one you're removing.
How do I know my old switch needs replacing?
Common signs are a gritty or sticky feel, a knob that hangs between positions, or one position that quits working while the others still click. Those point to worn contacts inside the selector.
Do I need to cut power before installing it?
Yes. Shut off both the 120V AC feeding the air conditioner and the 12V DC at the thermostat side before you open the control box. Label or photograph the wires as you remove them so heat and cool land on the correct positions.
