Coleman-Mach Bluetooth Ceiling Assembly App Control Prep

Use the Coleman-Mach Bluetooth ceiling assemblies page to capture assembly, app, control, and pairing details before support.

Owner-safe checklist

Record the Coleman-Mach ceiling assembly model, app name, pairing state, thermostat or control behavior, RV model, and when the symptom appears.
Save screenshots of the app message, photos of the control panel, model paperwork, and any compatibility notes.
Turn the HVAC system off for electrical smell, abnormal heat, repeated unsafe behavior, or water intrusion.
Use Coleman-Mach support or qualified RV HVAC service for installed power, ceiling assembly internals, compatibility, parts, warranty, or repair decisions.
