Coleman Mach Compressor Relay 1460-1171 | 6633 46413
Coleman Mach Compressor Relay 1460-1171 | 6633 46413 — Product description
The Coleman 1460-1171 is the compressor relay for the Mach 6633 and 46413 rooftop air conditioners. Small part, big job. It's the switch that hands power to the compressor when your thermostat calls for cooling, and it's a common, cheap fix when the fan runs but the air won't turn cold.
The Coleman 1460-1171 is the genuine replacement compressor relay for the Mach 6633 and 46413 rooftop air conditioners. It's a small part with a big job. When your thermostat calls for cooling, this relay is what hands power to the compressor so the unit actually starts pulling heat out of the coach.
Here's where it usually comes up. Your Mach unit's fan spins fine, you can feel air moving through the vents, but nothing's coming out cold. That's the classic sign the compressor isn't getting the signal to kick on, and a tired relay is one of the first things a tech checks. It's a cheap part to rule out before you start assuming the compressor itself has died, which is a far bigger and more expensive job. Swapping this in is a common fix worth trying first.
Because it's the genuine Coleman part, it drops into the 6633 and 46413 control wiring without adapters or guesswork. The internal contacts are sized for the load the compressor actually pulls, which is exactly why owners get burned buying a generic relay that clicks a few times and fails again in a season. One thing worth doing before you order: match your model number off the data label on the AC chassis. The Mach line has a lot of siblings and the relays aren't all interchangeable, so you want to confirm you've got a 6633 or 46413 on the roof.
Install is straightforward if you're handy. Kill the shore power and pull the breaker before you open anything up, then it's a matter of pulling the shroud, finding the relay in the control box, and swapping it onto the same terminals. If you're comfortable reading a wiring diagram, you'll have it done quickly. If not, any RV tech can handle it in a few minutes. Either way, you're back to cold air without the cost of a new unit.

Frequently asked questions
Which Coleman Mach models does this relay fit?
It's the genuine replacement for the Mach 6633 and 46413 rooftop air conditioners. If you've got a different Mach model on the roof, check with us before ordering, because the relays across the line aren't all the same.
What does the compressor relay actually do?
When your thermostat calls for cooling, this relay passes power to the compressor so it starts running. Without a working relay, the compressor never kicks on and the unit just blows the room-temperature air the fan is already moving.
My AC fan runs but the air isn't cold. Is this the part?
It's one of the first things worth checking. A fan-runs-but-no-cool symptom often points to the compressor not starting, and a failed relay is a common cause. It's a cheap part to rule out before you assume the compressor itself is gone.
How do I find my Coleman Mach model number?
Check the data label on the air conditioner chassis, usually reachable once you pull the interior ceiling shroud or look at the roof unit. Confirm it reads 6633 or 46413 before you order this relay.
Is this a genuine Coleman part?
Yes. This is the genuine Coleman relay, manufacturer part number 1460-1171, not a generic substitute.
Do I need an electrician to replace it?
If you're comfortable pulling the shroud and reading a wiring diagram, it's a straightforward swap. Always kill the shore power and pull the breaker first. If you'd rather not open the control box, any RV service tech can do it quickly.
