What does this selector switch replace and fit?

This selector switch is built to match the Coleman-Mach 6759-3251 control used in many RV air conditioner and heat pump models. It fits the same panel cutout and wiring pattern as the factory switch so you can replace a worn or damaged control without rewiring. Check your unit's model number and panel dimensions before ordering to confirm compatibility.

If unsure, consult an RV technician to avoid electrical hazards or damage to the HVAC system.

Will this switch improve performance or longevity?

The selector switch itself does not alter HVAC performance but restores control functionality so you can select modes such as cool, heat, fan, or off. Replacing a faulty switch prevents stray wiring or intermittent contacts that can lead to erratic operation. For improved longevity, pair replacement with a visual inspection of nearby wiring and controls.
