NATE ICE A/C, Exam Questions &
Answers. 100% Accurate. Rated A+
A compressor does not run, although the condenser fan is operating. Reading the compressor windings,
the measured resistance between R to S is 5 ohms, R to C is open, and S to C is open. The problem is due
to: - ✔✔-internal overload being open.
A compressor with tight bearings will cause the amperage draw to: - ✔✔-rise above normal.
A correct statement about a hard start kit is that it: - ✔✔-increases starting torque.
A correct statement concerning a relay is that it: - ✔✔-consists of one or more contacts actuated by a
solenoid coil.
Across an R-22 suction line drier, how much pressure drop indicates changing the drier? - ✔✔-3 psig
After a vacuum has been pulled to 500 microns, a pressure rise in a system, followed by a leveling-off at
1500 microns, most likely indicates the: - ✔✔-presence of moisture.
After a vacuum pump has been used, a continuous pressure rise in the system most likely indicates the: -
✔✔-existence of leak.
If the fan switch on a thermostat sub-base is set to ON and the blower motor is cycling on and off, the
most probable cause is in the: - ✔✔-motor overload.
In a compressor, the internal overload senses the winding temperature and: - ✔✔-amperage in the
compressor circuit.
