Understanding How Your Norcold Refrigerator Works
Before diving into troubleshooting, it’s essential to understand how your Norcold RV refrigerator operates. Norcold refrigerators typically use one of two technologies: absorption cooling or compressor cooling.
Absorption Cooling
Absorption refrigerators work by using a heat source to evaporate ammonia. The system then relies on a complex interaction of refrigerant gases and heat exchangers to create a cooling effect. Here are its main components:
- Heat Source: Propane or electric heating elements provide the required energy to evaporate ammonia.
- Evaporator: This component’s job is to absorb heat from the refrigerator’s interior, producing the cooling effect.
- Condenser: As the ammonia gas flows through this part, it loses heat and condenses back into a liquid.
Compressor Cooling
Compressor refrigerators operate similarly to home refrigerators but on a smaller scale. They use a compressor to circulate refrigerant and achieve cooling. They generally cool faster and are more efficient than absorption units.
Understanding these mechanisms will help you diagnose the problem more effectively.
