Amana-Goodman B1370150 Pressure Switch

The Amana-Goodman B1370150 Pressure Switch is a critical safety component designed for precise furnace draft inducer monitoring. Rated at -0.85" PF SPST, this genuine OEM replacement part ensures the vent motor is generating sufficient negative pressure before allowing the ignition sequence to proceed. It serves as a direct drop-in for legacy part numbers B1370149 and DB1370151, maintaining the integrity of the original system engineering. Engineered for compatibility with a wide range of Amana, Goodman, and Janitrol gas furnaces, this switch prevents hazardous operation by detecting venting obstructions or inducer failure. For HVAC contractors, utilizing this factory-direct component facilitates a reliable furnace pressure switch repair, ensuring the vacuum signal matches the manufacturer's specific set point. Its Single Pole Single Throw (SPST) configuration provides a clean electrical path, reducing nuisance codes and ensuring consistent performance in high-cycle heating applications.

• Precise Calibration: Factory-set at -0.85" WC to match specific Goodman furnace specifications.
• Broad Compatibility: Replaces older models including B1370149 and DB1370151.
• OEM Reliability: Genuine Goodman replacement part ensures exact fitment and terminal alignment.
• Safety Compliance: Critical HVAC safety switch prevents burner operation under poor venting conditions.

What causes a -0.85" pressure switch to fail?
Failure is often attributed to a ruptured internal diaphragm, moisture in the sensing lines, or a failing draft inducer motor that cannot reach the required -0.85" WC pressure rating.

Can I use a universal pressure switch instead of the B1370150?
While universal switches exist, using the specific Amana-Goodman B1370150 is recommended to ensure the set point and reset point align perfectly with the original equipment’s logic board.

How do I verify if this switch is compatible with my unit?
Check the data plate on your existing switch. If it lists -0.85" PF and matches the Goodman B1370150 part number, this is the correct technical replacement.
