Final answer:
Both statements provided by Technician A and Technician B are incorrect regarding the windings of a compressor. A reading of less than 10 ohms to ground indicates a potential short, and the start winding typically has a higher resistance than the run winding. The correct option is D.
Step-by-step explanation:
Technician A vs. Technician B Statements
Technician "A" claims that a reading of 10 ohms or less from the common terminal to ground suggests the motor is okay.
This statement is incorrect, as such a low resistance value could indicate a short to the ground, which is a malfunction. Normally, the resistance to ground should be very high, typically over a few megohms, indicating no short.
Technician "B" states that the resistance of the start winding should always be less than the resistance of the run winding.
This statement is incorrect. In many cases, the start winding will have higher resistance because it is made of thinner wire or more turns to create higher impedance at startup, helping the motor to develop more torque. After the start, a centrifugal switch or electronic relay disconnects the start winding.
Therefore, the correct answer to which statement is correct is D. Neither statement.
