Description
Nordic Cooling Unit 6592 for Dometic NDR1292, NDR1492, RM7732 & RM1282
The Nordic Cooling Unit 6592 is a replacement absorption cooling unit designed for select large Dometic RV refrigerators. It is built specifically for the Dometic NDR1292, NDR1492, RM7732, and RM1282 refrigerator families and provides an alternative to replacing the entire refrigerator when the original cooling unit has failed.
Nordic’s own application chart lists 6592 for all four of these Dometic models.
Models It Fits
The Nordic 6592 fits:
-
Dometic NDR1292
-
Dometic NDR1492
-
Dometic RM7732
-
Dometic RM1282
Nordic identifies these four models under the same 6592 cooling-unit application.
New-Build Replacement Cooling Unit
Current listings identify the Nordic 6592 as a new-build cooling unit rather than a remanufactured factory core. It is manufactured with replacement steel tubing and new insulation components for the boiler and foam-pack areas.
That distinction is important for customers comparing cooling-unit replacement options.
What the Cooling Unit Does
The cooling unit is the sealed absorption system mounted to the rear of the refrigerator.
It contains the boiler, absorber tubing, condenser, evaporator, and refrigerant solution responsible for creating refrigeration without a conventional compressor.
If the sealed cooling unit fails, the refrigerator may still have working controls, heaters, and gas components but no longer cool properly.
Signs of a Failed Cooling Unit
A failed or failing cooling unit may cause:
-
Refrigerator does not cool on either propane or electric
-
Freezer becomes only slightly cool while the fresh-food compartment stays warm
-
Yellow residue or ammonia odor around the rear cooling unit
-
Boiler area becomes hot but cooling does not occur
-
Cooling performance gradually deteriorates
-
Refrigerator works poorly even after heaters, burner, thermistor, and controls have been verified
-
Internal blockage in the absorption system
A no-cooling condition should be diagnosed before replacing the cooling unit, because failed heating elements, burner problems, control-board issues, thermistors, or poor ventilation can produce similar symptoms.
Built for Large Legacy Dometic Refrigerators
The NDR1292, NDR1492, RM7732, and RM1282 are large absorption refrigerators commonly found in older Class A motorhomes and fifth wheels.
Because these refrigerator sizes and cabinet openings can be difficult to replace with a modern unit, installing a replacement cooling unit can allow the original refrigerator cabinet, doors, trim, and controls to remain in service.
Climate-Controlled Charging & Calibration
Nordic states that its cooling units are charged in a controlled environment and that computerized calibration equipment is used to measure the chemical density of the absorption solution.
This is intended to provide consistent cooling performance and correct charge balance.
New Components
Current Nordic 6592 listings specify:
-
New steel tubing
-
New foam pack
-
New paint
-
New boiler-box insulation
-
Newly charged absorption solution
Estimated Install Time
Cooling-unit replacement is a substantial refrigerator repair and commonly requires several hours.
Typical installation involves:
-
Removing the refrigerator from the RV cabinet.
-
Disconnecting propane and electrical connections.
-
Removing the original cooling unit from the refrigerator cabinet.
-
Cleaning and preparing the evaporator-contact surfaces.
-
Installing and sealing the replacement cooling unit.
-
Reinstalling heaters, burner components, insulation, and wiring.
-
Reinstalling the refrigerator in the RV.
-
Leak-testing the propane system.
-
Testing refrigerator operation.
Professional installation is recommended if you are not experienced with RV absorption refrigerators and LP gas appliances.
Installation Notes
Proper installation is critical to cooling performance.
The evaporator sections of the replacement cooling unit must make solid contact with the refrigerator cabinet, and the foam pack and insulation must be properly sealed.
Poor thermal contact or incorrect installation can result in weak cooling even when the replacement cooling unit itself is operating correctly.
The refrigerator must also remain properly ventilated and reasonably level during operation.
Before Ordering
Verify the complete refrigerator model number on the data plate.
The Nordic 6592 is designed specifically for:
NDR1292 / NDR1492 / RM7732 / RM1282
Do not select a cooling unit based only on refrigerator size or appearance.
