The latest addition to our line of replacements for Onan® RV Gen Set Controls is the 56-4320-00. This is a direct replacement for the Onan® 300-4320 used in Microlite Model KY, Spec. B-E.

Also offered is the 56-4923-00. An exact replacement for Onan® P/N 300-4923, this control fits Microlite Model KY, Spec. F-H.

As with all our replacement controls, these are built in the USA with top-quality materials.

New Test Equipment

For quick Onan RV Gen Set troubleshooting, the sensible solution is the new Point-MAN RV Regulator Breakout Box. The Point-MAN simply plugs in between the generator and the regulator giving you easy access to eight key circuits needed for effective troubleshooting. It provides the necessary circuit access while your multi-meter does the rest.
