Armstrong Furnace R102613-02 Pressure Switch

The Armstrong Furnace R102613-02 Pressure Switch is a critical safety component designed for 2-stage high-efficiency gas furnaces. This dual-actuator pressure switch monitors the combustion blower's vacuum levels, ensuring proper venting before allowing the ignition sequence to proceed. Calibrated for 1.00" WC and 0.45" WC set points, this OEM replacement prevents operation during flue obstructions or inducer motor failure. Built to withstand high-temperature environments, the R102613-02 furnace switch features durable internal diaphragms and 3/16-inch spade terminals for secure electrical connections. When diagnosing furnace pressure switch stuck open codes or secondary heat exchanger drainage issues, verify that your Armstrong inducer vacuum levels match these specific tolerances. This HVAC pressure switch is essential for maintaining the pressure safety circuit in high-efficiency Allied Air and Armstrong Air heating systems, providing precise sensing for low-fire and high-fire operation cycles.

• Dual-Stage Calibration: Pre-set to 1.00 PF and 0.45 PF for accurate 2-stage combustion monitoring.
• OEM Compatibility: Exact replacement for Allied Air and Armstrong parts, ensuring correct fitment without bracket modification.
• Safety Compliance: Prevents gas valve activation if the venting system is compromised or the inducer fails.
• Industrial Build: Engineered for resilience against the heat cycles of 90% AFUE furnaces.

What are the symptoms of a failing R102613-02 pressure switch?
Common indicators include the inducer motor running continuously without ignition, or the furnace control board flashing a pressure switch lockout code. Technicians should use a manometer to verify the static pressure before replacing the 1.00/0.45 switch.

Does this switch replace single-stage pressure switches?
No, this is a 2-stage pressure switch designed specifically for dual-stage heating systems. It cannot be bypassed or substituted with single-setting switches without compromising the furnace safety circuit.

Can moisture cause this switch to fail?
Yes, in high-efficiency furnaces, condensate backup in the pressure tubing can reach the diaphragm, leading to premature failure. Always clear the collector box ports when installing a new Armstrong R102613-02.
