Both the primary switching MOSFET and secondary Schottky diodes require isolated aluminum heatsinks. Under a full 264W load, active cooling (a 12V or 24V chassis fan) is highly recommended.
The output pin of connects to the Gate of Q1 through a small resistor (typically 10 to 47 Ohms) to limit ringing. When the gate goes high, Q1 allows current to flow from the negative terminal of the 24V motor/load down to the system ground. 5.

Check for 24V across the coil pins when activated. If voltage is present but there is no click, the coil is burnt out. If there is no voltage, trace back to the driving transistor or the flyback diode, which may have shorted out.
