Safety & CodesQuestion 109 of 110
A high-pressure safety switch on refrigeration equipment protects the system by doing what?
a.Adding refrigerant
b.Interrupting the compressor circuit if discharge pressure becomes dangerously high
c.Draining condensate
d.Boosting the fan speed
Explanation
A high-pressure switch opens the control circuit and stops the compressor when head pressure rises to an unsafe level, such as from a failed condenser fan or blocked airflow. This prevents component rupture and damage. It should be diagnosed and reset only after the underlying cause is corrected.
