Suburban Furnace Core Module Service Prep

Use the Suburban furnace core replacement module page to capture model and service details before support.

Owner-safe checklist

• Record the furnace model, coach model, cabin-heat symptom, thermostat setting, shutdown behavior, fuel status, and any visible label details.
• Save photos of the thermostat, visible grille, exterior access door from a safe location, label if visible, and product page used for comparison.
• Shut the furnace down for fuel odor, exhaust concern, soot, abnormal heat, repeated shutdown, or unsafe operation.
• Use Suburban support or qualified RV furnace service for fuel system, venting, installed power, module fit, parts, warranty, or repair decisions.
