A properly-connected capacitor shouldn't have current flow in a DC circuit, so it should not warm up.
All this time, the voltage and current controls seemed to be working – although it seemed to want to stay in current limit quite a lot – maybe the load, which is a motor, needs a capacitor. Rather than don my safety

A motor capacitor is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor). Motor capacitors are used with single-phase electric motors that are in turn use

Free QuoteThe use of a capacitor with a different capacitance can increase motor vibration, heat generation, power consumption, torque variation, and unstable operation. If the capacitance is too high, motor torque will increase, but overheating and excessive vibration may occur. If capacitance is too low, torque will drop.
Capacitor motor with a speed limiting governor device. Start capacitors lag the voltage to the rotor windings creating a phase shift between field windings and rotor windings. Without the start capacitor, the north and south magnetic fields will line up and the motor hums and will only start spinning when phsically turned, creating a phase shift.
A start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 75% of the full speed, and is then taken out of the circuit, often by a centrifugal switch that releases at that speed.
The dedicated capacitor creates a 90 electrical phase shift from the auxiliary (capacitor) phase to the main phase. Using the wrong capacitor can shift this away from the 90 degrees, and the resulting inefficiency can cause the motor to overheat with inconsistent torque or speed performance.
A difference in the capacitance in the capacitor will affect both rated speed and rated torque as the operating point shifts away from its maximum efficiency. If you use 2 of the same exact motors with vastly different capacitors, you will produce vastly different results. Once maximum efficiency is lost, heat generation increases for the motor.
A motor capacitor is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field.
