Where in the freezer is frost formed?
Reason
If the door is not tightly closed or cool air leaks in summer when humidity level is high,
frost will form. Frost occurs due to encounter of hot air (outside) and cold air (inside)
when door is opened and closed.
It occurs more frequently in summer or monsoon season when the humidity level is higher.
The phenomenon will eventually disappear when the weather gets cooler.
How to fix
Check food arrangement and shelf assembly to see if the door can be closed firmly.
Clean frost with dry cloth.
