ASE A7 Practice Test

ASE defines heating and air conditioning as an individual service area. This area includes all components and systems both mechanical and electronic that are related to a vehicle’s heating and air conditioning system.

Tests.com's ASE A1 Practice Test was written by Dr. John Kershaw, an ASE test prep expert: ASE test question developer; ASE Certified Master Technician; ASE Master Truck Technician; and Auto Industry Technical Instructor.  Dr. Kershaw was among the first to receive ASE certification in 1972.

AC System Service, Diagnosis and Repair

1. This question has the word EXCEPT. For this question, look for the choice that could NOT fit the described situation. Read the entire question carefully before choosing your answer. All of the following statements are correct regarding an air conditioning performance test, EXCEPT:
2. During an air conditioning performance test, the technician notices that the compressor outlet is hot. Technician A says this is a normal condition. Technician B says the air conditioning system is overcharged. Who is right?
3. Technician A says when the condenser airflow is restricted the pressure is high in both high and low lines. Technician B says an indication of low refrigerant is when both the high and low sides show low pressure. Who is right?
4. Which of the problems listed below will cause the manifold gauge readings shown in the illustration?
 

Refrigeration System Diagnosis and Repair - Compressor and Clutch

5. This question has the word EXCEPT. For this question, look for the choice that could NOT fit the described situation. Read the entire question carefully before choosing your answer. All of the following tasks are performed when replacing an AC compressor, EXCEPT:
6. A compressor clutch will not engage. Power and ground at the clutch coil are good. Which of the following is the MOST likely cause?
7. On a manual air conditioning system without automatic control, the compressor clutch does not operate. Technician A says there is a failed compressor thermal protector. Technician B says there is an incorrectly adjusted temperature door. Who is right?
CDA Practice Test
8. Using a DMM (digital multimeter), a technician measures 12 volts at the clutch coil, but it will not engage. Technician A says a bad clutch coil could be the cause. Technician B says a bad clutch coil ground could be the cause. Who is right?

Refrigeration System - Evaporator, Condenser and Related Components

9. This question has the word EXCEPT. For this question, look for the choice that could NOT fit the described situation. Read the entire question carefully before choosing your answer. All of the following issues regarding a receiver/dryer are correct, EXCEPT:
10. This question has the word EXCEPT. For this question, look for the choice that could NOT cause the described situation. Read the entire question carefully before choosing your answer. All of the following are true regarding the expansion valve, EXCEPT:
11. Technician A says all air conditioning connections use a gasket or O-ring to seal the system. Technician B says when replacing O-rings you lubricate the O-ring with the correct refrigerant oil to prevent nicks and ease installation. Who is right?
12. A concern of intermittent AC cooling is being diagnosed. The gauge set shows intermittently high and low side pressure gauge readings and the high side intermittently drops to 100 psi. Which of the following is the MOST likely cause?

Heating and Engine Cooling Systems Diagnosis and Repair

13. Technician A says a defective thermostat can cause the engine to operate at too cold of a temperature. Technician B says if the thermostat is stuck closed it can make a pinging or banging sound. Who is right?
14. Two technicians are describing heater diagnosis. Technician A says one heater hose is hot to the touch and the other hose is cold when the heater core is functioning okay. Technician B says the upper radiator hose should be at engine operating temperature, which is very hot to the touch. Who is right?
15. What high-side and low-side pressure gauge readings would a technician find if the condenser fan were inoperative?
16. Which of the following conditions is the MOST likely cause of a vehicle overheating?

Operating Systems and Related Controls Diagnosis and Repair

17. Technician A says a misadjusted temperature door could cause a poor heat complaint. Technician B says a defective resistor trio can cause a no high blower condition. Who is right?
18. Technician A says a radiator should always be inspected for leaks before installing a rebuilt engine. Technician B says overheating during slow in-town driving can be caused by an electric cooling fan fault. Who is right?
19. The heater blows out only cold air at operating temperature. Technician A says a stuck closed thermostat could be the cause. Technician B says the cooling system could be low on coolant. Who is right?
20. If a cooling system operates at too cool an operating temperature, the engine will do which of the following?
