The Norcold 639593 is the OEM rear lower power/control board used throughout the Norcold Polar N7, N8, and N10 refrigerator families. It serves as one of the refrigerator's primary electronic control components, communicating with the upper display/eyebrow board and controlling refrigerator operation.

Norcold 639593 Fits N7, N8 and N10 Polar Refrigerators

One of the best things about the 639593 Norcold power board is that fitment is relatively simple.

The 639593 is used on the following Norcold Polar refrigerator families:

• N7

• NA7

• N8

• NA8

• N10

• NA10

This includes common models such as:

• N7V

If your Norcold refrigerator model begins with N7, NA7, N8, NA8, N10 or NA10, the 639593 is the rear power board used for this refrigerator family.

Your refrigerator model number can normally be found on the identification label located inside the fresh-food compartment.

Norcold 639593 vs. 638189 – They’re the Same Board

This is probably the biggest source of confusion surrounding this part.

You remove the refrigerator access panel, look at your existing board and see:

638189

Then you search for a replacement and keep finding:

639593

So which one do you need?

Norcold 639593 is the replacement part number you order.

The number 638189 may appear on the existing power board or its cover, while 639593 is the Norcold service/replacement part number. The 639593 is identified as replacing the legacy 638189 board.

So if you're standing behind your refrigerator staring at a board marked 638189, don't panic.

639593 is the replacement you're looking for.

What Does the Norcold 639593 Power Board Do?

The 639593 is often called several different things:

• Norcold power board

• Norcold control board

• Norcold circuit board

• Norcold lower control board

• Norcold rear power board

• Norcold main power board

They are generally referring to the same component in this application.

The board is located at the rear of the refrigerator and acts as a central electronic control point for refrigerator operation. It communicates with the upper control/display board and manages signals used to operate the refrigerator's systems.

When this board fails, the refrigerator can exhibit electrical or operational problems that can easily be mistaken for failures elsewhere in the refrigerator.

Signs Your Norcold 639593 Power Board May Be Bad

A failed power board can cause several different symptoms depending on how the board has failed.

Possible symptoms include:

• Refrigerator will not power on

• Refrigerator appears completely dead

• Intermittent refrigerator operation

• Refrigerator controls behaving unpredictably

• Refrigerator failing to operate correctly on one or more available power sources

• Communication problems between the rear board and upper control/display

• Visible damage or burned components on the circuit board

• Refrigerator receiving proper incoming power but failing to operate normally

A refrigerator that isn't working does not automatically mean the power board is bad. Incoming 12-volt DC power, fuses, wiring, grounds and other refrigerator components should still be checked before replacing electronic components.

But once testing leads back to the rear control board, 639593 is the OEM replacement board for the Norcold Polar families listed above.

Have a Norcold Board Marked 638189?

This deserves repeating because we get this question constantly.

If you pull the access panel off your refrigerator and find:

P/N 638189

you may have trouble finding a new part listed under that number.

Search for:

Norcold 639593

The 639593 is the current replacement/service part associated with the 638189 board used in these Polar refrigerators.

You do not need to find an old-stock board carrying 638189 simply because that's the number you see on your existing refrigerator.
