Question 76Refrigeration & AC - QMED

The correct answer is D) leaking door gaskets. Explanation: The symptoms described - slightly above normal refrigerated space temperature without reaching the desired minimum, and normal suction and discharge pressures - indicate that the refrigeration system is operating properly but there is an issue with the refrigerated space itself. Leaking door gaskets would allow warm air to enter the refrigerated space, preventing it from reaching the desired temperature, while not impacting the refrigeration system pressures. The other options, such as high cooling water temperature or a shortage of refrigerant, would likely result in abnormal system pressures, which is not the case here.
