In this comprehensive guide, we will delve into the signs that indicate whether your refrigerator compressor is functioning correctly or if it requires attention.
Understanding the Role of the Compressor in Your Refrigerator
The compressor is often described as the “heart” of your refrigerator. Think of it as a pump that circulates refrigerant through the system, facilitating the cooling process. Here’s a brief overview of how it works:
- Compression: The compressor takes in low-pressure refrigerant gas from the evaporator, compressing it into high-pressure gas.
- Condensation: The high-pressure gas moves to the condenser coils, where it releases heat and changes into liquid refrigerant.
- Expansion: The liquid refrigerant flows into the evaporator coils, evaporating and absorbing heat from the inside of the refrigerator.
- Cycle Continuation: This cycle continues, ensuring your refrigerator maintains the desired temperature.
Given this pivotal role, it is essential to know how to determine if the compressor is running.
