Replacement Onan Control Board
An exact replacement for Onan P/N 300-4320, the 56-4320 control fits Microlite Model KY Spec. B-E and is built in the USA with top-quality materials. More than just a replacement part, this new control has been re-designed and improved to eliminate known problems with the AC voltage sensing circuit that were frequent with the original control. The module is environmentally sealed by encapsulation in an automotive-grade urethane, is 100% repairable, and features our standard two-year warranty.
