How Does a Refrigerator Work?

How a Refrigerator Works

Most people don’t think about how a refrigerator works until it stops cooling. Knowing the basics can help you spot problems early. Here’s a simple breakdown from Nifty Nashville Appliance Repair.

Key Parts of a Refrigerator

Compressor

  • Acts as the motor and pump
  • Circulates refrigerant through the system

Condenser

  • Located on the back of the fridge
  • Releases heat into the surrounding air

Evaporator

  • Inside the fridge
  • Absorbs heat to cool the interior

Expansion Device

  • Reduces pressure on refrigerant
  • Helps it change back into a liquid

Thermostat

  • Monitors temperature
  • Signals the compressor to turn on when needed

How Refrigeration Works

  1. The thermostat detects a temperature rise and signals the compressor.
  2. The compressor pressurizes the refrigerant and turns it into a hot gas.
  3. The hot gas flows through the condenser coils, cools, and turns into a liquid.
  4. The liquid moves to the evaporator inside the fridge.
  5. It absorbs heat, cools the air, and turns back into a gas.
  6. The gas returns to the compressor, and the cycle starts over.

This process keeps your food at a safe, cold temperature.
