Lennox 10F76 Pressure Switch
When you're troubleshooting a furnace that won't initiate the ignition sequence, the Lennox 10F76 Pressure Switch is often the first logical checkpoint. This genuine OEM component is a 0.50" WC pressure switch designed specifically for Lennox, Armstrong, and Ducane gas furnaces. Engineered for precision, it features a single pole single throw (SPST) configuration and utilizes a dual 1/4" barb connection for seamless integration with existing vacuum tubing. This part, also identified by part number 101432-05, is technically identical to IS20102-3172, ensuring a drop-in replacement that eliminates the need for field modifications or bracket adjustments.
For service technicians, this furnace air pressure switch is critical for verifying proper inducer motor draft before allowing the gas valve to energize. Its purple dot identification helps prevent misapplication in the field, and the rugged diaphragm construction is built to withstand the high-cycle demands of modern high-efficiency heating systems. Whether you are performing an emergency furnace repair or a preventative system tune-up, using a Lennox replacement part ensures the safety and operational integrity of the combustion air proving circuit.
Key Benefits:- Direct OEM Compatibility: Verified replacement for Lennox 10F76, 101432-05, and Honeywell IS20102-3172.
- Precise Calibration: Factory-set at 0.50" Water Column to ensure exact safety compliance during the ignition cycle.
- Durable Construction: Features dual 1/4" barb connections and standard electrical terminals for a secure, professional fit.
- Safety Compliance: Crucial HVAC safety switch that prevents hazardous operation if the flue or intake is obstructed.
- Is the Lennox 10F76 the same as the IS20102-3172? Yes, these are identical components with the same 0.50" WC trip point and physical footprint.
- What does a purple dot on the switch signify? The purple dot is a factory color-coding used by Lennox to quickly identify the specific pressure rating (0.50" WC) for this model.
- Can I use this on Armstrong or Ducane units? Yes, since Lennox is the parent brand, this switch is a standard furnace repair part for many Armstrong and Ducane gas furnace models.
