No, the Amana GUCA045AX30 furnace does not need to be plugged in to reset the auxiliary limit switches. The process involves disconnecting the electrical power supply before checking or repairing the auxiliary limit control, then reinstalling the blower access door, and finally reapplying power to verify proper operation.
