Coleman 9430A3402 Cool Only RV Thermostat | Black
Coleman 9430A3402 Cool Only RV Thermostat | Black — Product description
The Coleman 9430A3402 is the cool-only wall thermostat for Coleman Mach RV air conditioners, finished in black. It runs the cooling side of your system and nothing else, so it's the simple, exact-fit replacement when your old control quits.
The Coleman 9430A3402 is the cool-only wall thermostat for Coleman Mach RV air conditioners, finished in black. If your rig still cools but the old control quit reading temperature, stopped cycling the compressor, or the buttons went dead, this is the direct replacement that gets your air back.
Cool only means exactly that. This control runs the air conditioning side and nothing else. There's no heat mode, no furnace tie-in, and no heat pump control. So if your coach has a gas furnace or a heat-pump AC you also want to run from the wall, this isn't the control for that job. But for a straight cooling setup, it's simple and it does the one thing well.
The black finish is there for a reason. A lot of newer coaches run darker interior trim, and a bright white thermostat sticks out on a dark wall. This one blends in. Functionally it's the same as the white version, just a different face color.
This is the genuine Coleman RVP replacement, so it speaks the same language as the rest of your Mach system out of the box. No adapters, no guessing at pin-outs, no fighting a universal control that half works. It drops onto the factory base and reads temperature the way the system expects.
Install is a wall swap. Kill the power at the breaker or unplug shore power first, pull the old control off its base, and match the low-voltage wires over to the new one. If you're comfortable with basic 12-volt work you can knock this out in a few minutes. If you're not sure which wire goes where, snap a photo of the old wiring before you disconnect anything. That one habit saves a lot of head-scratching.
One thing worth checking before you order: make sure your system is genuinely cool-only. If you've got heat or a heat pump and you buy this, you'll lose the ability to run those from the wall. When in doubt, give us the model number off your air conditioner and we'll confirm the right control before it ships.

Frequently asked questions
What does cool only mean on this thermostat?
It controls the air conditioning (cooling) side only. There's no heat mode, no furnace control, and no heat pump control. If you need to run heat from the wall, this isn't the right control.
Will this work with my Coleman Mach air conditioner?
It's the cool-only wall control for Coleman Mach systems. If you're not sure yours is cooling-only, send us the model number off the AC and we'll confirm the right part before it ships.
What's the difference between this and the white version?
Just the face color. This one's black to blend with darker interior trim. The function is the same.
Is this hard to install?
No. It's a wall swap. Cut the power first, pull the old control off its base, and move the low-voltage wires over. Snap a photo of the old wiring before you disconnect so you can match it exactly.
Can I use this if I have a heat pump?
No. This is cooling-only. A heat pump needs a heat-pump-capable control, and buying this would drop your ability to run heat from the wall.
Is this a genuine Coleman part?
Yes. It's the genuine Coleman RVP replacement, part number 9430A3402, and it drops onto the factory base without adapters.
