Electronic leak detectors are being discussed. Technician A checks for leaks with the engine off, the shop doors closed, and the overhead fans turned off. Technician B checks for leaks outdoors with the engine running. Who is correct?

Question

Quizplus · Accepted Answer

Technician A's method is correct because electronic leak detectors are sensitive and require a controlled environment to accurately detect leaks. Checking with the engine off, doors closed, and fans off minimizes air movement and external contaminants that could interfere with the detection process. Technician B's method is less effective because outdoor conditions and the running engine could disperse refrigerant, making leaks harder to detect.
