How to Install Norcold Cooling Units

By admin Mar 20, 2023

If your Norcold refrigerator isn’t cooling properly and smelling like ammonia, it may have a failing cooling unit. Fortunately, replacing a Norcold or Dometic RV fridge cooling unit can be less expensive than replacing the entire refrigerator.

Before installing the new unit into the refrigerator, run a layer of evaporator sealing tape around the outer edge of the evaporator foam pack and slats. Also, apply a thick layer of Thermo-Mastic to all of the tubes in the cooling unit.


The installation of Norcold Cooling Units is a fairly simple process. All that is required is a screwdriver and some basic knowledge of the refrigerator.

When the rear mounting screws are removed, the cooling unit is typically jiggled and lifted from the evaporator foam pack pocket (see the image on page 68). This can sometimes be difficult, particularly with Dometic cooling units where the frame member blocks the evaporator sealing tape.

If the evaporator sealant is not applied properly, there may be air and moisture in the fridge box that could cause corrosion or cooling problems.

To make sure that the thermal mastic gets a good transfer to the refrigerator box, set the cooling unit in the fridge box and dry-fit it. Then trim the foam block if needed to get an optimum fit. Apply a bead of transfer mastic to the foam block and to the freezer tubes. Then fasten the cooling unit to the refrigerator.

Second, take a look at the boiler tube to make sure it’s properly insulated and positioned. If it’s not, the unit will overheat and fail.
