Heater Contactor 22 Replacement

The Dayton DAP0022 is a heater contactor built for HVAC systems in recreational vehicles. It serves as a direct replacement when the original switching component fails or shows wear. Installers and RV owners use it to restore reliable heating control without modifying the existing wiring.

Upgrades From Failed OEM Contactors

This part replaces a contactor that no longer pulls in cleanly or that chatters under load. The jump is worth it when the furnace cycles erratically or the coil overheats. It matches the factory mounting and terminal layout so the swap stays straightforward.

Compatible With Grainger 6E811 And 6E812

The contactor fits systems specified for Grainger part numbers 6E811 and 6E812. It handles the standard coil voltages and contact ratings those references imply. It is not suited for applications that demand higher amperage or a different pole configuration.
