Fridge Temperature Optimizer

Check whether your fridge temperature is set ideally for longer food life and lower power use.

The recommended fridge temperature is between 4 and 7 °C (39-45 °F). Colder settings waste energy; warmer settings risk food spoiling faster.

Pro tips

  • The freezer compartment should be set to -18 °C (0 °F).
  • A thermometer inside the fridge is more accurate than the dial scale.

Frequently Asked Questions

What temperature should a fridge be set to?

4-5°C in the main compartment is recommended – colder wastes electricity, warmer shortens how long food stays fresh.

Why is my fridge too warm?

Common causes are a leaky door seal, overly tight packing that blocks air circulation, or standing too close to a heat source.

How much electricity does a lower fridge temperature cost?

Every degree colder increases power consumption by roughly 5-8% – the recommended 4-5°C is a good balance between freshness and energy cost.

Where in a fridge is it coldest?

Usually in the lower area near the back wall – that's where sensitive food like meat and fish should go; the door is the warmest zone.
