If you keep opening the fridge door to find your food has frozen, then it’s probably set too cold. This can be an easy fix as you just need to adjust the temperature. There should be a dial or touch controls that’ll help you sort this, but if you’re not sure how check the product manual. Just remember it can take time for the temperature to change, so give the fridge 24 hours to adjust.
If that doesn’t solve the issue, you can pop a thermometer in, leave it overnight and see what temperature your fridge is running at.
