The INTERNATIONAL COMFORT PRODUCTS 1184614 is a genuine OEM high pressure switch assembly designed to protect refrigeration and cooling systems from excessive refrigerant pressure events. When system pressure exceeds a safe threshold, the switch interrupts operation to prevent compressor and component damage. Rated at 240 volts, this switch assembly is a direct-fit replacement that eliminates wiring guesswork and reduces callback risk. Licensed HVAC technicians handling refrigerant-side diagnostics and system protection controls are the primary installers of this component.
This high pressure switch assembly is suited for residential split-system cooling equipment where refrigerant circuit protection is required. Confirmed compatible models include HSA536GKA101, HSA530GKA101, and H4A324GKF101. It is well suited for service calls where the existing switch has failed open, failed closed, or has lost calibration, causing nuisance trips or undetected high pressure conditions.
Confirmed compatible with the following INTERNATIONAL COMFORT PRODUCTS models: HSA536GKA101, HSA530GKA101, and H4A324GKF101.
Installation should be performed by a licensed HVAC technician with EPA Section 608 certification, as this component interfaces with the refrigerant circuit. Disconnect and lock out all electrical power to the unit before servicing. Recover refrigerant per applicable EPA regulations before removing pressure-side components. Verify system operating pressures are within normal range after reinstallation before returning the unit to service.
