Amana-Goodman B1370157 Pressure Switch

When you're troubleshooting a furnace that refuses to ignite, diagnosing a faulty Amana-Goodman B1370157 Pressure Switch is step one. This genuine OEM Single-Pole Single-Throw (SPST) switch is calibrated to a precise -0.38" WC (Water Column) pressure rating, ensuring your inducer motor creates the necessary vacuum for safe combustion. Built with a durable 1/4" barb connection, this component serves as a critical safety limit, monitoring negative air pressure and only allowing the ignition signal to pass when the system reaches its defined operational range. Whether you are servicing a Goodman, Amana, or Janitrol furnace, this component integrates seamlessly with the existing control board and inducer assembly to maintain system integrity. Every furnace air pressure switch is factory-tested to verify its set point, providing contractors with a reliable drop-in replacement that eliminates the guesswork of universal "one-size-fits-all" alternatives. Maintain peak performance in GSMS and GSM model series by utilizing this exact-spec HVAC induction set point switch.

Key Benefits:

• OEM Precision: Calibrated specifically to -0.38" WC for accurate negative pressure sensing in Amana and Goodman systems.
• Durable Construction: Features a high-quality SPST internal contact and a standard 1/4" barb for quick, secure vacuum line attachment.
• Safety Compliance: Prevents furnace ignition if venting is obstructed or the inducer fan fails to reach proper RPM.
• Broad Compatibility: Engineered as a direct replacement for various Goodman and Amana furnace models, ensuring exact fitment.
• Factory Verified: Each unit is shipped factory-direct and undergoes rigorous testing to confirm the pressure threshold before dispatch.

Common Questions:

What are the symptoms of a failing Amana-Goodman B1370157?
Common signs include the furnace inducer motor running without the igniter glowing, or a specific pressure switch lockout code appearing on the control board LED.

Can I use a switch with a different "WC rating?
No. Using a switch with a different water column rating can lead to unsafe operation or frequent nuisance trips. Always match the -0.38" WC specification for this circuit.

Is this switch compatible with Janitrol units?
Yes, as Goodman and Amana manufactured many Janitrol branded furnaces, this B1370157 is a standard replacement for many of those older models.
