Gas Heat ESCO Practice Exam

If the technician were to conclude that A is the correct answer, they would be incorrect. A low speed wire reading 0 ohms in a 120 VAC furnace motor indicates that there is a short circuit in the winding. This means that there is an unintended connection between two points of the circuit, causing the wire to have extremely low resistance. Choosing option B would also be incorrect, as the issue is not with the speed setting but with the internal wiring of the motor. Option D can also be eliminated as the wires are not disconnected, but rather shorted. Therefore, the only correct conclusion that a technician can make is that the winding is shorted and needs to be repaired or replaced.
