Question of the day

Which action is a typical function of the high pressure switch when pressures are high?

Explanation:
High pressure protection. The high pressure switch serves as a safety control that shuts the compressor off when the refrigerant high-side pressure reaches a set limit. If conditions cause the high-side pressure to spike—such as blocked airflow across the condenser, an overcharge, or very high ambient temperatures—the switch opens the electrical circuit to the compressor (or its contactor), preventing damage from overpressure. The typical cut-off range for many systems is around 350–400 psi, though the exact value depends on the refrigerant and design. This safety function is distinct from protecting against low suction pressure (that’s the low-pressure switch) and is not used to adjust evaporator temperature. Allowing the compressor to continue running under high pressure can lead to component damage, so the automatic shutoff is the correct behavior.

    The lack of sections means you get a broad mix, which I found closer to the real test flow. It’s easy to navigate, and the MCQs build good familiarity with HVAC concepts, from combustion to refrigerant cycles.
