It has been miserably cold , and raining as well . It was so cold in the kitchen that we had the novel experience of opening the frig door and having warm air come out . When we have our evening glass of champagne the glasses are colder than the liquid , so you get half an inch in the bottom of the glass and the rest is froth .

Question: What is the reason that warm air comes out of the refrigerator ?
Answer: The temperature near the refrigerator is VERY hot .The manual reversing vacuum valve is on in the refrigerator .None of the above choices .It is actually at or below freezing in the room where the refrigerator is .
