Dutchaire 6642B 90-Degree Cooling Unit for Norcold N611

Dutchaire 6642B is a replacement absorption cooling unit for a compatible Norcold N611 RV refrigerator that uses a 90-degree heating-element arrangement. Dutchaire makes the replacement cooling unit; Norcold is the refrigerator brand it is designed to service. The electrical heating element is not included.

Cooling Unit Details

• Cooling unit part number: 6642B
• Cooling unit brand: Dutchaire
• Primary listed application: Norcold N611 with 90-degree heater arrangement
• Condition: Supplier catalogue identifies a new-build replacement cooling unit, not a remanufactured unit
• Heating element: Not included; select the proper compatible heater separately when needed

Verify the Heater Angle and Refrigerator

The Dutchaire catalog also lists selected Norcold 600-series refrigerator applications. That list is not a substitute for matching the existing boiler, heater bend, refrigerator model and relevant serial information. This 6642B 90-degree configuration is distinct from Dutchaire 6642A's 45-degree arrangement. Do not order based on the N611 family name alone.

Supply and Warranty

This is the replacement cooling unit, not a complete Norcold refrigerator. Supplier documentation lists a limited three-year warranty for newly manufactured units; verify current warranty coverage and replacement authorization with the seller. Absorption-system replacement should follow the applicable refrigeration service and safety instructions.
