Referring to a refrigerator as "he" or "she" is not a common practice in everyday language. In English, inanimate objects like refrigerators are typically referred to using the pronoun "it." This is because grammatically, objects do not have a gender, and there's no inherent gender associated with most inanimate things.
People may sometimes give human-like qualities or names to their belongings, including their refrigerators, as a form of affection or personification. For example, someone might playfully say, "He's been keeping our food nice and cold all summer," or "She's been with us for years and never let us down." However, this usage is more about personalizing the object and doesn't imply that the refrigerator actually has a gender.
Ultimately, it's a matter of individual preference and style whether someone chooses to use gendered pronouns for their refrigerator or any other inanimate object, but it's not a common or standard practice in the English language.
