The Dometic fan motor wire harness (Part# 4450013255) is the critical connector that delivers power and control signals to your RV's roof vent or furnace fan motor. If your fan motor won't turn on, cycles erratically, or shows electrical connection issues, a damaged or corroded harness is often the culprit. This OEM replacement harness restores reliable operation to keep your RV's ventilation and heating systems running smoothly.

• Direct OEM replacement for Dometic fan motor assemblies
• Factory-sealed connectors resist moisture and corrosion
