Description
Product Summary
The Honeywell L404F1383 is a pressure switch from Honeywell, described by the manufacturer as: mercury free pressuretrol 10-150 PSI close on rise Air/Steam auto reset. It replaces L404B1346 L404B1551.
A pressure switch proves that air, water or refrigerant pressure is where it should be before allowing the equipment to run. On furnaces it proves the inducer's draft; on boilers and steam systems it controls or limits the operating pressure. Replace a switch that does not close with the correct pressure applied, or that opens and closes erratically. Check hoses, ports and venting first.
