For your Coleman Mach 7300 Series, I recommend checking out the Advent Air Replacement RV Air Conditioner for Coleman Setup # ACCOL150.

This air conditioner will easily replace your existing Coleman Mach air conditioner by using the included conversion brackets and wiring harness.

This Air conditioner also has a 15,000 Btu per hour rating, is compatible with ductless and ducted systems, and has thermal insulation that regulates temperature and prevents the motor from overheating.

I have a 1986 7300 rooftop air conditioner on a Fleetwood bounder P32. I need to replacement unit. You mentioned the Advent Air Replacement RV Air Conditioner for Coleman Setup # ACCOL150 to someone else but I am unable to find that unit. Is it a compatible replacement for my old unit? What do you recommend?

@Jb Hey JB, with a unit that old the best option will be to replace the whole AC system; rooftop unit, controller, distribution box and thermostat. For that I recommend the following: - Advent Air RV Air Conditioner System - Manual - 13,500 Btu - White - R32 # ADV23SR The ACCOL150 you mentioned is no longer available. It did come with an adapter for a Coleman system but honestly I hated that adapter because it rarely worked as advertised. Replacing the whole AC system will be a much better option. Its the only way we can guarantee everything will work together.

@JesseM Sorry, I meant a 1996 7300 rooftop air conditioner on a Fleetwood bounder P32. Not a 1986.
