(Heat Pump Models)
The loss of charge protector senses the pressure in the liquid line and will open its contacts on a drop in pressure. The low pressure control will automatically reset itself with a rise in pressure.
The low pressure control is designed to cut-out (open) at approximately 7 PSIG. It will automatically cut-in (close) at approximately 25 PSIG.
Test for continuity using a VOM and if not as above, replace the control.
