The Norcold brand is America’s leading manufacturer of RV refrigerators. These units are known for performance and reliability.
If your Norcold or Dometic RV refrigerator is not cooling, there is a good chance you have an issue with your cooling unit. If your fridge isn’t cooling, there are several things you can check for to determine whether the cooling unit needs replacing.
Thermo-Mastic
Thermal mastic is a heat conducting material that conducts heat four times better than a purely mechanical connection. It has been designed to improve heat transfer between touching surfaces in the refrigeration industry.
It is a one-component, non-drying mastic/sealant that promotes the heat transfer between adjacent metallic surfaces. It can be used for a variety of purposes in domestic refrigeration.
Typical uses include promoting the heat transfer between the evaporator coil and temperature sensor, heat sink or defrost thermostat. It can also be used in ice maker molds to seal the mold heater thermostat to the ice maker mold and improve the efficiency of the ice maker operation.
Thermo-Mastic is a low cost thermal mastic that is compatible with polyurethane foam insulation in refrigeration systems. It is a chlorinated paraffin, filler and wetting agent formulation.
Foam Sealant
Insulating foam sealant, also known as expanding foam, is a quick and easy way to air-seal gaps and cracks. This creates a tight building envelope, which improves energy efficiency and reduces utility bills.
Foam sealant is a polyurethane (PU) foam that cures by making contact with moisture. Its cure rate varies according to product-specific formulation, temperature, humidity and the amount of foam being sprayed.
In addition to helping control moisture, insulating foam sealant can make a home more comfortable by stopping drafts and minimizing air-borne sound transmission from gaps and cracks around doors, windows, attics and floor boards. Additionally, insulated foam sealant can help to prevent mold and mildew growth.
When replacing a norcold rv refrigerators cooling unit, it is important to install the cooling unit into a refrigerator box with an airtight fit. This can be done by dry-fitting the foam block and adjusting it as needed, keeping the freezer tubes level with the refrigerator compartment floor.
Foil Tape
Foil tape is made from aluminum, copper, or lead foil on an adhesive backing. It is used for a wide range of applications, including sealing and insulating ductwork in HVAC systems.
Compared to duct tape, foil tape has better adhesion and thermal stability and can be applied in extreme temperature conditions. It also holds up well to moisture and chemicals.
It is also fire-resistant, which is a great feature for any tape that you will use in the outdoors. ECHOtape’s all-weather aluminum foil tape is coated with a superior performance flame-retardant acrylic adhesive, which works equally well in extreme hot and cold weather conditions.
This pressure sensitive foil tape is designed to create air-tight seals in ductwork and ventilation systems. It is specifically designed to meet the most stringent HVAC industry standards for durability and adherence.
Spray Foam
Spray foam is a great insulation choice for homeowners looking to improve their home’s comfort, energy efficiency and safety. This type of insulation creates an air-tight seal that helps prevent temperature fluctuations in a building and promotes a more consistent climate.
Another huge perk of this type of insulation is that it also protects against moisture and rot. This can make a difference between having a dry, healthy and comfortable home or a house that could be at risk for mold, mildew and rot.
This is why it’s so important to make sure that you get a professional to install this type of insulation in your home. The result is a more efficient, healthy, stronger and happier home!
