CHAPTER 1 PRODUCT BRIEF This product is a newly developed frost-free refrigerator of our company. The product's external appearance is special and decent sculpting. It is the whole box hull structure, poured foam behind, ensured foamed layer thickness equality. So the heat preservation function is more excellent It is the whole foamed door structure, designed to a thin door gasket structure that can keep cold air effect better and with...

Three, break down analysis: 一、refrigerate room isn’t cool or is cool not better Break down analysis: 1)the fan is bad or there is the stopper and its rotate speed is much low(it is much more possibility in after two kind.) 2)Refrigerator air road is not free so that breeze is much little or not.

much low(it is much more possibility in after two kind.) 2) Refrigerant lacks or leaks 3) Frost on the evaporate is thick ,or the ice is much more(see a behind reason analysis)so that refrigerator room is not cold or cold much better. 4) The compressor doesn't operate or is bad(see a behind reason analysis).
