Would you happen to know the part number for the wiring harness or small white adapter that plugs into the Control Circuit board for Atwood water heater. The piece burned out and I would like to replace just that piece. The circuit board is P/N 91346. Thanks

@Jason Does it look like the Replacement Circuit Board Adapter Plug for Dometic Atwood Water Heaters item # DMC47FR? If not and you can find a part number on your adapter I can try to look it up that way.

@JerredH It’s the 4 pin piece that is connected tot he wire. I had to replace the circuit board. Now would like to replace just the plastic adapter piece that connects to to board from the wiring harness. Unfortunately it’s melted so no P/N. Thanks
