Description
The Armstrong Furnace R102699-01 is an OEM replacement pressure switch engineered specifically for compatible Armstrong Furnace heating systems. Set at a precise 0.60″ water column (w.c.) setpoint, this pressure switch monitors the negative pressure generated by the inducer motor to verify safe combustion venting conditions before allowing the furnace to proceed through its ignition sequence.
How It Works
The pressure switch is a critical safety component in modern induced-draft and condensing furnaces. It senses the differential pressure created by the draft inducer blower. If the inducer fails to establish the correct airflow — due to a blocked flue, failed motor, or other venting issue — the pressure switch remains open, preventing ignition and protecting against unsafe operation.
