Same issue. PD V1 control board is #230-4041 that is discontinued
However, you can install. PD V2 control board with very basic knowledge

Now the caveat.
The V2 uses a different connector.
If youre uncomfortable doing it yourself, take your old control board with the flat plug and the new control board to an electronic shop and have them "splice" your old plug inline between control board and new plug and your set
Imworking on the same solution this winter
Good luck!!
