How often does a modern fridge defrost?

Question

Usually every day my bottom drawer style fridge's freezer temperature goes up to 15-20 degrees and then back to zero overnight. I'm wondering if this is the defrost cycle I am seeing on the built in display?

Answer 1

They defrost each day at the same time.  There is a timer that controls this taking 24 hours to cycle.  I found this link that is good.  Hope this helps.
