Do fridges work harder with more items to cool?

Question

If there are more items in the fridge does each one cause the fridge to have a higher uptime when maintaining colder temperatures?

When you open the door more items means more surface area is exposed to warm air. More heat is absorbed by more items than fewer items. The fridge will then have to work that heat energy out again.

The difference is very little because air has low heat capacity and conductivity.

For maintaining temperature with door closed it doesn’t matter.
