Coleman-Mach Thermostat Controlled Ceiling Assembly Prep

Use the Coleman-Mach thermostat-controlled ceiling assembly page to identify control package and model details before support.

Owner-safe checklist

Record the ceiling assembly type, thermostat model if known, air-conditioner model, control symptoms, mode setting, and any label visible from inside the coach.
Save photos of the thermostat, ceiling assembly face, controls, filters from normal access, and product page used for comparison.
Use only normal thermostat and filter-access steps before support.
Use Coleman-Mach support or qualified RV HVAC service for installed power, ceiling assembly access, parts, warranty, or replacement decisions.
