Armstrong Furnace R102613-01 Pressure Switch

The Armstrong Furnace R102613-01 Pressure Switch is a critical OEM safety component engineered for 2-stage 80% and 90% gas furnaces. As a dual-rated switch, it monitors negative pressure at two distinct set points, .45" and .80" WC, ensuring the inducer motor is moving sufficient combustion air before allow the ignition sequence to proceed. This genuine Armstrong Air replacement part is built with a high-sensitivity diaphragm and rugged housing to withstand the thermal cycling and humidity common in modern condensing and non-condensing systems. Failure of this switch often results in a furnace lockout or an error code indicating a pressure switch stuck open. By maintaining precise calibration for high-fire and low-fire cycles, this 02613-01 replacement switch restores optimal combustion efficiency and prevents dangerous exhaust buildup. Compatible with various Lennox, Ducane, and Concord models, it is designed for direct wire-to-wire installation to minimize downtime on the job site.

• Dual-Stage Calibration: Pre-set to .45" and .80" WC for accurate staging of the inducer motor and combustion blower.
• High-Performance Safety: Prevents furnace operation if the flue is obstructed or the inducer fails, protecting the heat exchanger.
• OEM Compatibility: Exact replacement for 102613-01, 45697-001, and R45697-001, ensuring perfect fitment without modifications.
• Industrial Build Quality: Features reinforced ports and gold-plated contacts to resist corrosion and mechanical fatigue.

• Can I use a single-stage switch to replace this 2-stage model? No. This 2-stage pressure switch is required for multi-stage furnaces to accurately sense the specific vacuum levels needed for both high and low heat cycles.
• What causes this switch to trip? Beyond a faulty switch, common issues include a clogged collector box port, moisture in the sensing tubing, or a restricted chimney/vent pipe.
• Is this compatible with Ducane units? Yes, this part is an official OEM replacement for various brands under the Lennox International umbrella, including Armstrong Air, Ducane, and Concord.
