Norcold 1172-340 / 628663 Display Board | N62 & N82 3-Way Fridges

Restore control panel function to your Norcold 3-way absorption refrigerator with the Norcold Optical Display Board (Part 1172-340, also sold as 628663) — the front-mounted user interface for N62 and N82 series refrigerators. Provides status lights, temperature controls, and mode selection buttons. Available at The RV Surplus.

⚠️ For 3-Way Absorption Fridges — NOT DC Compressor Models

This board is for 3-way (AC / DC / LP gas) absorption refrigerators — the N62 and N82 series. It does NOT fit DC compressor models like the N8DC or N10DC families (those use different control boards entirely).

If your fridge runs on 120V, 12V, and propane, this is the right board. If your fridge is DC-only, this is not your part.

⭐ Part Number Lineage

• Current part number: 1172-340 (this listing)
• Also sold as: 628663
• Replaces older: 619355

All three numbers refer to the same optical display board for this fridge family. If your dealer or parts list quoted any of these, this is the correct part.

⭐ Compatible Norcold Models — 3-Way Absorption

• Norcold N62 series
• Norcold N82 series

⚠️ Verify your model number before ordering. The model/serial label is on the inside of the fresh-food compartment, typically on the left sidewall.

⭐ What This Does

The optical display board is the front-mounted user interface for your Norcold 3-way refrigerator, providing:

• Status lights (power, mode, fault indicators)
• Temperature control buttons
• Mode selection (AC / DC / LP gas / Auto)
• On/off control

⚠️ Professional Installation Recommended

Installation involves opening the refrigerator control housing, disconnecting the failed board, and connecting the replacement board with correct wiring alignment. Should be performed by a qualified RV service technician unless you have prior experience with Norcold refrigerator electronics.

⚠️ Before Replacing the Board

Not every control panel issue is a bad board. Before you order:

• Check 12V DC at the fridge — low voltage reads as a dead or glitchy panel
• Inspect the ribbon cable between the display board and the main power board — reseating often restores function
• Check for fault codes on the display before anything stops working — codes narrow the fault to a specific subsystem
• Verify power at the main board — a dead display can be caused by a bad upstream power board, not the display itself
