- Fan Control Pressure Switch
- Step Van HVAC system
- With lead and connector
This pressure switch monitors refrigerant pressure within the air conditioning system and controls condenser fan operation based on preset pressure thresholds. When system pressure rises or falls outside normal operating ranges, the switch signals the fan circuit to engage or disengage, helping to regulate system pressure, improve cooling efficiency, and prevent compressor or condenser damage.
