There is no reset for this code. Check to make sure the blue wire at the power board and optical board has a tight connection. If it does, you should replace this power board 639593.

Will this replace a Main Control Board 1 P.N.638189?

4 years ago • Staff Answer

The 638189 that you're referring to is just a manufacturing stamp that goes on the Norcold 639593 board. Yes, this is the correct power board for all N7, NA7, N8, NA8, N10, and NA10 model refrigerators and it will have that 638189 physically marked on the board.

This would indicate that you likely have a ventilation issue with that unit. Check out our tech blog on articles for improving air flow behind the refrigerator.

When I power up my na8lx fridge i get a no dt code.

This is due to a connection issue or a failure in one of the two boards (most likely the rear power board). First, check for a good connection on the solid blue wire at the power board and optical board. If it's making good contact, we highly recommend replacing the power board:

NA8LXR - The freezer works perfect but fridge struggles to cool to 8c.

This is likely due to ventilation or off level operation. When you're in a hot climate, it's really important that the ventilation in the back is clear and that you have good air flow.
