Understanding How Norcold Refrigerators Work
Before jumping into troubleshooting, it’s essential to understand how Norcold refrigerators operate. Many Norcold models utilize a process called absorption cooling, which is different from the traditional compressor cooling found in most household refrigerators.
The Absorption Cooling Cycle
In absorption refrigerators, a mixture of ammonia and water undergoes a cycle to create refrigeration. Here’s how it works:
- Heating: A heat source—usually propane gas, but it can also be electric—heats a solution of ammonia and water.
- Evaporation: As the solution heats, ammonia evaporates and travels through a condenser, cooling the interior of the refrigerator.
- Condensation and Absorption: Ammonia then condenses and returns to the mix with water, allowing the cycle to restart.
This cycle relies on a variety of factors to function appropriately, which means several issues can arise, leading to a refrigerator that does not cool effectively.
