Which of the following component failures will cause an increase in refrigerant pressures?
A. Faulty evaporator fan motor
B. Refrigerant leak
C. Faulty condenser fan motor
D. Faulty liquid line solenoid
Answer (2)
The faulty condenser fan motor is responsible for increased refrigerant pressures due to its role in heat dissipation. When it fails, heat is not adequately removed from the refrigerant, leading to higher pressures. Therefore, the correct answer is C: Faulty condenser fan motor.
;
A faulty condenser fan motor will cause an increase in refrigerant pressures due to reduced heat dissipation. The other components either do not impact pressure or result in a decrease. Understanding the roles of these components helps in diagnosing HVAC issues effectively. ;
