To provide a control device for a sewing machine, by which appropriateness of a solenoid equipped on a sewing machine can be judged.

The control device 100 for a sewing machine switches on/off of power supplied for a presser lifting solenoid 6a for actuating a presser foot 6 from a drive power source to continuously or intermittently energize the solenoid 6a. The control device 100 for a sewing machine detects a current value flowing to the solenoid 6a when the presser foot 6 is actuated and judges the current value respectively detected in continuous energizing and intermittent energizing is whether or not within a predetermined appropriate range respectively set corresponding to continuous energizing or intermittent energizing, When a current value detected in at least one of continuous energizing or intermittent energizing, the solenoid 6a is regarded as not appropriate and power supply for the solenoid 6a is stopped.
