Furnace Air Pressure Switch ClimaTek HVAC Control 3×3 Compact

Description

Product Overview

The ClimaTek Furnace Air Pressure Switch is engineered to deliver precise pressure regulation for residential heating systems. Built to replace Goodman part numbers B1370142 and B13701‑42, this component integrates seamlessly into existing furnace assemblies, eliminating the need for extensive modifications. Its compact 3 × 3 inch footprint, weighing just three ounces, allows it to fit into tight cabinet spaces while maintaining robust performance. Constructed from high‑grade polymer and metal contacts, the switch resists corrosion, wear, and temperature extremes, ensuring a long service life even in demanding environments. The design incorporates a calibrated diaphragm that reacts quickly to changes in combustion air pressure, sending accurate signals to the furnace control board to modulate burner operation. This results in improved fuel efficiency, reduced emissions, and a more consistent indoor temperature. The product dimensions and lightweight nature also simplify handling during installation, making it an ideal choice for both professional HVAC technicians and experienced DIY homeowners.

Usage

Designed for a wide range of residential heating applications, the ClimaTek pressure switch is suitable for single‑stage, two‑stage, and variable‑speed furnaces. It excels in environments where reliable pressure sensing is critical, such as homes located in colder climates or regions with fluctuating gas pressure. Installers can mount the switch directly onto the furnace’s pressure tap, connecting the two lead wires to the control board as indicated in the wiring diagram. The switch operates effectively across a temperature range of -20 °F to 150 °F, making it resilient to both winter chill and summer heat. Its compact size means it can be positioned in tight spaces without obstructing airflow or other components, preserving the furnace’s overall efficiency. Whether you are upgrading an aging system, performing routine maintenance, or restoring a furnace after a component failure, this pressure switch provides a reliable, plug‑and‑play solution that minimizes downtime and restores optimal operation.

FAQ

What furnace models are compatible with this pressure switch?

The switch is a direct replacement for Goodman part numbers B1370142 and B13701‑42, which are used in many single‑stage and two‑stage residential furnaces. It also fits other brands that use the same pressure tap dimensions and electrical connections, but we recommend verifying the mounting pattern before purchase.

How do I install the pressure switch safely?

Begin by turning off power to the furnace at the breaker. Locate the existing pressure tap, remove the old switch, and attach the new ClimaTek unit using the supplied mounting hardware. Connect the two lead wires to the control board according to the wiring diagram, ensuring a secure connection. After installation, restore power and run the furnace through a complete heating cycle to confirm proper operation.

Can this switch be used in high‑efficiency furnaces?

Yes. The ClimaTek pressure switch is designed to operate across a wide temperature range and can handle the pressure differentials found in high‑efficiency condensing furnaces. Its accurate sensing helps maintain the precise airflow required for optimal heat exchange and condensation management.

What warranty does the product include?

All ClimaTek pressure switches come with a one‑year limited warranty covering defects in materials and workmanship. If the switch fails within the warranty period, contact our support team for a replacement or repair, subject to proof of purchase.

Is professional installation required?

While the switch is designed for straightforward installation, we recommend that a qualified HVAC technician perform the replacement to ensure compliance with local codes and to verify proper system integration. Experienced DIY homeowners may also install the part safely by following the provided instructions and taking appropriate safety precautions.
