ASE A/C Exam 100% ACCURATE AND UPDATED!

An EATC air conditioning system has low fan speed operation during high demand situations, like in direct sunlight. Technician A says this is because something is covering the sun load sensor's photo diode. Technician B says a sun load sensor is a variable resistor and can be tested with an ohmmeter. Who is correct? - ANSWERBoth A and B A gurgling sound is heard coming from inside the dashboard of a vehicle. Technician A says this is air trapped in the heater core. Technician B says this noise can be caused by a blown head gasket. Who is correct? - ANSWERBoth A and B A manifold gauge indicates a system has low discharge pressure. The MOST likely cause of this condition is: - ANSWERA damaged compressor reed valve. The compressor is rapidly cycling on and off on a CCOT (cycling clutch orifice tube) air conditioning system. Technician A says this condition can be caused by a low refrigerant charge. Technician B says this could be caused by a faulty clutch cycling switch. Who is correct? - ANSWERBoth A and B Technician A says while performing a retrofit from R-12 refrigerant to R134a refrigerant, the refrigerant must be recovered into a dedicated cylinder, they cannot be mixed. Technician B says R-12 refrigerant functions at higher pressures than R-134a refrigerant does. Who is correct? - ANSWERTech A
