During tests to discover why a refrigeration compressor is running continuously, it is determined that the refrigerated space temperature is slightly above normal without ever reaching the desired minimum temperature. Suction and discharge pressures are normal for the corresponding box temperature. In this situation, what should you suspect?

Question

Accepted Answer

Option D: leaking door gaskets. When a compressor runs continuously with normal pressures but box temperatures remain elevated, external heat infiltration is typically the culprit. Leaking door gaskets allow warm ambient air to continuously enter the refrigerated space.
