Quizplus · Accepted Answer

The thermostat being closed indicates that the desired temperature has not been reached yet, which means the compressor needs to continue running. Therefore, the timer motor should be permitted to operate only when the compressor is in operation and the thermostat is closed. The other choices are unrelated to the operation of the compressor run timer.
