7. a broken compressor reed valve
#1. Prior to recovery, an unknown refrigerant is identified. The technician should:
the correct answer is recover it and treat it as contaminated
#2. A compressor clutch will not engage. During testing, the technician finds there is 14.2V and a good ground at the clutch coil connector. Which of these could be the cause?
the correct answer is an incorrect air gap
#3. Technician A says that evacuating an A/C system will remove air and moisture from the system. Technician B says that evacuating an A/C system will remove dirt particles from the system. Who is right?
the correct answer is A only
#4. To charge an A/C system while it is running, the refrigerant should be added to:
the correct answer is the low side only
#5. With the A/C system operating at an ambient (outside) temperature of 85° F, the low pressure gauge reads 5 psi and the high pressure gauge reads 105 psi. What do these readings indicate?
the correct answer is low refrigerant level
#6. The technician measures 14.2 volts at the A/C clutch coil, but the A/C clutch will not engage. Technician A says that a failed clutch coil could be the cause. Technician B says that a failed clutch coil ground could be the cause. Who is right?
the correct answer is both A and B
#7. The high side pressure in an A/C system is above specs. Any of these could be the cause EXCEPT:
the correct answer is a broken compressor reed valve
