Coleman-Mach Electric Heat Strip Mode Service Prep

Use the Coleman-Mach electric heat strips page to capture accessory, heat-mode, model, and service-prep details before support.

Owner-safe checklist

Record the Coleman-Mach model, heat-strip accessory if known, heat mode, thermostat setting, airflow behavior, and whether cooling modes still work.
Save photos of the thermostat or control, model paperwork, accessory paperwork, and service notes from normal owner access.
Turn the HVAC system off for electrical smell, abnormal heat, repeated shutoff, or unsafe power behavior.
Use Coleman-Mach support or qualified RV HVAC service for installed power, heat-strip accessory, compatibility, parts, warranty, or repair decisions.
