Abstract
A cut-out circuit for an air conditioner protects the air conditioning system components when subjected to low pressure conditions, without manually resetting the system after low pressure cut-out. The cut-out circuit preferably includes a relay, connectable to a voltage source through a normally closed low pressure switch to a compressor clutch, the relay operable in a closed state to output a voltage from the voltage source through the low pressure switch to the clutch, and in an open state to interrupt the voltage. The low pressure switch may open responsive to a low pressure condition interrupting voltage flow to the clutch. The circuit includes a normally open high pressure switch, connected to the relay and a voltage source, operable to close responsive to a high pressure condition, to output a voltage from a voltage source to the relay for changing the relay operating state to open.
