Nordic Cooling Unit 5562-606A for Dometic RM3662, RM3663, RM2652 & RM3652

The Nordic Cooling Unit 5562-606A is a remanufactured replacement absorption cooling unit for select Dometic RV refrigerators using the new-style flat vertical gas-valve bracket.

It is designed for specific versions of the Dometic RM3662, RM3663, RM2652, and RM3652 refrigerator families. Nordic identifies the 5562-606A as the 606A / new-style cooling-unit configuration for these models.

Models It Fits

The Nordic 5562-606A fits select:

• Dometic RM3662

• Dometic RM3663

• Dometic RM2652

• Dometic RM3652

The refrigerator must use the new-style flat vertical gas-valve bracket configuration.

How to Verify Fitment

Before ordering, inspect the existing cooling unit.

Nordic recommends first looking for the cooling-unit model number stamped or labeled on the absorber tank. For this cooling unit, look for:

606A

If the model number is not visible, identify the gas-valve mounting bracket.

The 5562-606A uses the newer flat, vertical bracket where the gas valve assembly mounts.

This visual check is important because Dometic used more than one cooling-unit configuration within these refrigerator model families.

New-Style Flat Gas-Valve Bracket

The defining fitment characteristic of the 5562-606A is the gas-valve bracket built into the cooling unit.

The correct configuration has a:

Flat, vertical gas-valve mounting bracket

If your existing cooling unit uses this style of bracket, the 5562-606A is the appropriate Nordic configuration for the listed refrigerator models.

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, and refrigerant solution responsible for producing refrigeration.

Heat from either the propane burner or electric heating element drives the absorption cycle. If the cooling unit itself fails, the refrigerator can still have functioning lights, controls, heating elements, and burner components while no longer cooling properly.

Signs of a Failed Cooling Unit

A failed or restricted cooling unit may cause:

• Refrigerator does not cool on either propane or electric

• Freezer cools 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 electric heater operate

• Internal blockage develops in the absorption system

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

Remanufactured Nordic Cooling Unit

The 5562-606A is sold as a remanufactured replacement cooling unit.

Nordic rebuilds absorption cooling units for RV refrigerators as an alternative to replacing the complete refrigerator. Current catalog listings identify 5562-606A specifically as the remanufactured 606A cooling unit for these Dometic applications.

Why Replace the Cooling Unit?

If the refrigerator cabinet, doors, controls, and other components are still in good condition, replacing the cooling unit allows the original refrigerator to stay in the RV.

That can avoid:

• Replacing the entire refrigerator

• Cabinet modifications

• Changing exterior venting

• Reworking refrigerator trim

• Changing door clearances

• Replacing still-functional refrigerator components

For older Dometic absorption refrigerators, the cooling unit is often the major component that actually needs repair.

Core Return

The original cooling-unit core is generally required to be returned to Nordic for warranty eligibility on this model.

Nordic documentation specifically identifies the 5562-606A among the cooling units requiring the exchange core to be returned.

Keep the original cooling unit and follow the included core-return instructions.

Installation Overview

Cooling-unit replacement involves transferring the refrigerator’s reusable components to the replacement cooling unit.

Typical installation includes:

1. Remove the refrigerator from the RV cabinet.

2. Disconnect the propane and electrical connections.

3. Remove the original cooling unit from the refrigerator cabinet.

4. Clean the evaporator contact surfaces.

5. Install and seal the Nordic replacement cooling unit.

6. Reinstall the heating elements and burner components.

7. Reconnect the 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 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
