Nordic Cooling Unit 5582-806A for Dometic RM2852, RM2862, RM3852, RM3862, RM3863, RM4872, RM4873 & NDR1062

The Nordic Cooling Unit 5582-806A is a remanufactured replacement absorption cooling unit for select Dometic RV refrigerators using the newer 806A cooling-unit configuration.

The 5582-806A is specifically designed for refrigerators equipped with the new-style flat, vertical gas-valve mounting bracket. Because Dometic used both older and newer cooling-unit configurations within many of these refrigerator model families, the existing cooling unit should be checked before ordering.

Models It Fits

The Nordic 5582-806A fits the newer 806A versions of:

• Dometic DM2852RBX

• Dometic NDR1062

• Dometic RM2852

• Dometic RM2862

• Dometic RM3852

• Dometic RM3862

• Dometic RM3863

• Dometic RM4872

• Dometic RM4873

Nordic’s current application chart identifies these models under the 5582-806A cooling unit.

How to Verify Fitment

Before ordering, inspect the original cooling unit.

The easiest ways to identify the correct configuration are:

• Look on the absorber tank for cooling-unit model number 806A

• Inspect the gas-valve mounting bracket

The 5582-806A uses the new-style flat, vertical bracket where the gas-valve assembly mounts.

If the existing cooling unit has this flat vertical bracket, the 5582-806A is the correct Nordic configuration for the listed refrigerator models.

New-Style 806A Configuration

The defining feature of the 5582-806A is its new-style gas-valve bracket.

Nordic distinguishes these cooling units as follows:

806A = New Style = Flat Vertical Gas-Valve Bracket

That makes a quick visual inspection of the existing cooling unit one of the easiest ways to confirm fitment before ordering.

What the Cooling Unit Does

The cooling unit is the sealed absorption system mounted to the rear of the refrigerator.

It contains the:

• Boiler

• Condenser

• Absorber tubing

• Evaporator

• Internal refrigerant solution

Heat from either the LP gas burner or electric heating element drives the absorption cycle and produces refrigeration.

If the cooling unit itself fails, the refrigerator may still have working lights, controls, burner components, and heating elements while no longer cooling properly.

Signs of a Failed Cooling Unit

A failed or restricted cooling unit may cause:

• Refrigerator does not cool on propane or electric

• Freezer gets cold but fresh-food compartment remains warm

• Cooling performance gradually becomes weaker

• Boiler area becomes hot but little cooling occurs

• Yellow residue appears around the cooling unit

• Ammonia odor is present

• Refrigerator stops cooling even though the burner and AC heating element work

• Internal blockage develops in the absorption system

Before replacing the cooling unit, verify that the problem is not caused by the thermistor, heating element, burner, control board, ventilation, or another service component.

Remanufactured Replacement Cooling Unit

The Nordic 5582-806A is a remanufactured replacement cooling unit designed to restore the sealed refrigeration system while allowing the original refrigerator cabinet, doors, controls, and trim to remain in service.

Current Nordic catalog listings describe the 5582-806A as a remanufactured 806A cooling unit for these Dometic refrigerator applications.

Why Replace the Cooling Unit?

If the refrigerator cabinet and controls are still in good condition, replacing the cooling unit can be an effective alternative to replacing the entire refrigerator.

Keeping the original refrigerator can avoid:

• Cabinet modifications

• Changing exterior venting

• New refrigerator trim

• Door-clearance problems

• Electrical modifications

• Replacing still-functional refrigerator components

For many older Dometic absorption refrigerators, the cooling unit is the primary component that actually needs replacement.

Core Return

Nordic remanufactured cooling units typically require the original cooling unit to be returned as a core.

Keep the original cooling unit until the replacement has been installed and follow the included core-return instructions.

Installation Overview

Cooling-unit replacement is a straightforward remove-and-replace repair.

Typical installation includes:

1. Remove the refrigerator from the RV cabinet.

2. Disconnect propane and electrical connections.

3. Remove the original cooling unit.

4. Clean the evaporator-contact surfaces.

5. Install and seal the Nordic replacement cooling unit.

6. Reinstall the AC heating elements and burner components.

7. Reconnect wiring and propane.

8. Reinstall the refrigerator.

9. Leak-test the propane connection.

10. Turn the refrigerator on and verify cooling operation.

Installation Notes

Good thermal contact between the replacement cooling unit and refrigerator cabinet is important for proper performance.

Make sure:

• Evaporator surfaces are seated firmly

• Foam and insulation are properly sealed

• Heating elements are fully inserted

• Burner components are correctly positioned

• Upper and lower refrigerator vents are unobstructed

• The refrigerator is operated reasonably level
