Owner-safe checklist

• Record the SW12D model, item number, control setting, water temperature symptom, recent weather, and any owner-facing indicator.
• Save photos of the exterior label, control switch, and visible product information from normal owner access.
• Shut the water heater down for odor, leak, overheating, freeze concern, or repeated fault behavior, then contact Suburban support or qualified RV service.
