It get Hot

I unfreeze the refrigerator about one hour.I clean using baking soda powder to put off foul odor.Tata told me to put a charcoal inside the refrigerator to avoid bad odor from stored food
After, cleaning I notice the refrigerator is very very hot in all side.I unplug it.Let it cool down for an hour.Then, I plug it again but still it is hot all day! I thought it was already defective! I told people in the house not to open the refrigerator for two days.I notice it cool down.It's summer so refrigerator should not be frequently open to avoid hot atmosphere.
