Why Replace Your Interlock Switch?
A faulty or worn interlock switch can cause nuisance shutdowns, prevent furnace ignition, or — in a worst-case scenario — allow the furnace to operate with an open access panel. Replacing a failed interlock switch with a genuine OEM part restores proper safety function and ensures the system performs as designed. Always verify compatibility with your specific Armstrong furnace model before installation.
