How will an extremely dirty air filter affect the amp draw of a PSC centrifugal blower motor?
 
  A) The fan motor current is not affected by the air filter.
  B) It will cause the motor current to increase because it is working harder to move the air through the system.
  C) The motor will begin to draw negative amps due to the magnetic-thermal motor winding reaction to the increased temperature caused by reduced airflow.
  D) It will cause the motor current to decrease because the fan will be moving less air.

Question 2

With the system operating, a technician gets a reading of 20 volts between the L1 and T1 terminals at the contacts of the contactor. This tells the technician that:
 
  A) The contacts are defective because they have a measurable voltage drop.
  B) The compressor is defective.
  C) The contactor is operating correctly.
  D) The transformer is defective because the voltage should be 24 volts.
