Nordyne 1018505R Replacement Normally Open Pressure Switch
The Nordyne 1018505R is a direct replacement normally open (NO) pressure switch engineered to restore proper draft-proving and safety interlock function in compatible Nordyne heating equipment. With a 0.20″ W.C. set point, this switch monitors combustion air pressure and ensures the inducer blower is operating correctly before allowing burner ignition — protecting both the equipment and the occupants it serves.
Key Features
