OEM Carrier LP Gas Pressure Switch HK02LB008 for Model TCACCYCRLPELEV006A00

This is the factory OEM LP (liquid propane) gas pressure switch for the Carrier TCACCYCRLPELEV006A00. The gas pressure switch monitors incoming LP gas supply pressure and proves safe operating pressure before allowing ignition to proceed. When supply pressure falls below or exceeds the factory set-point, the switch opens the control circuit and sends the system into a no-heat lockout condition. Common symptoms of failure include a furnace that attempts ignition but immediately locks out, an error code indicating pressure fault, or a unit that runs the inducer motor but never advances to the ignition stage. Note: OEM part HK02LB008 has been discontinued by Carrier; direct OEM successor is HK02MB008. Stock of HK02LB008 remains available — order today while supplies last.

Photograph all wiring connections and hose port routing before removal. The switch is typically secured with one screw and connected via a 1/4" hose barb to the burner manifold.

Compatibility: Designed for Carrier model TCACCYCRLPELEV006A00 LP gas heating equipment. Always verify your unit's data plate fuel type (LP vs. natural gas) and existing switch set-point before ordering — LP and natural gas pressure switches are not interchangeable.
