Drop-In Replacement for Coleman Mach Air AC

Updated 06/18/2020 | Published 06/16/2020

Question:

my 2003 itasca motorhome has two ducted coleman mach rooftop units. the front unit model: 8633B876 sn: 110217085 has failed. ive wandered the airxcel website looking for a DIRECT replacement unit, without much success. id like that replacement to use the same 14.25x14.25 roof opening, the existing thermostat and interior grill if possible. i cant even manage to find specs regarding height of the units on the airxcel web site. lots of talk about profile but no specifics on actual height. mu current unit is, roughly, 14 high. can you recommend a drop-in replacement for my failed unit? you carry many brands and i would appreciate your recommendation, even if its not a coleman built, as long as its a direct drop-in replacement. thanks much for your help.

We do have replacements for a Coleman Mach Air AC, so long as your current thermostat and relay box are working, and so long as it is not a 6000 Series or 7000 Series, which based on my research your 8633B876 unit is not, though you will want to verify that.

There are 13,500 Btu or 15,000 Btu units and either Black or White in color:

- Black: Advent Air Replacement RV Air Conditioner for Coleman Setup - 15,000 Btu # ACCOL150B or 13,500 Btu # ACCOL135B

- White: Advent Air Replacement RV Air Conditioner for Coleman Setup - 15,000 Btu # ACCOL150 or 13,500 Btu # ACCOL135
