Unsurpassed Three Year Warranty!

Control Board - Replaces Onan 300-3056, 300-3687, 300-3687-01, *300-3950

* IMPORTANT: Onan part # 300-3950 is not a control board, but rather a KIT to convert the 300-3056 or the 300-3687 series boards to the newer 300-3763-01 board. The kit contains a new 300-3763-01 board, an adapter harness & instructions, etc.  It is much cheaper and simpler to simply replace the original 300-3056 or 300-3687 series boards with the Dino board shown here. However, if your genset is already upgraded with the new 300-3950 kit, you will need the PC Board for Onan 300-3763, 300-3763-01, 02, 03, 04, 300-5268-01

Do you have this symptom? When you push in the start switch, the generator starts up, but dies as soon as you leave go? You may have a defective voltage regulator instead of (or in addition to) a control board - See this troubleshooting

Note: We can supply the genuine Onan parts if you prefer.
