Amana-Goodman 11177113 Pressure Switch

The Amana-Goodman 11177113 Pressure Switch is a critical safety component designed for high-efficiency furnace and HVAC systems. This OEM replacement part serves as a dual level pressure switch, monitoring the pressure across the heat exchanger and venting system to ensure proper combustion and flue gas extraction. Constructed with robust diaphragm materials to resist cycling fatigue, the 11177113 is engineered to detect negative pressure fluctuations that could indicate a blocked vent or a failing inducer motor. Field technicians rely on this specific furnace pressure switch for its precise set-points, which prevent the ignition sequence if airflow is inadequate. Proper installation requires verifying the trip point calibration to match the original equipment specifications. Integrating this Goodman replacement switch ensures system reliability and prevents nuisance trips during heavy heating cycles. When troubleshooting a furnace pressure switch stuck open error code, this component provides the exact electrical resistance and mechanical response required for compatible Amana-Goodman air handlers and furnaces.

• Precision Calibration: Factory-set trip points ensure the system operates within safe static pressure limits.
• Long-Term Durability: Designed to withstand constant cycling and high-temperature environments near the draft inducer.
• Direct OEM Fit: Eliminates the need for field modifications, ensuring electrical compatibility with existing wiring harnesses.
• System Safety: Effectively monitors for heat exchanger obstructions or flue restrictions to prevent unsafe run conditions.

What causes a pressure switch error on a Goodman furnace?
Errors are typically caused by a restricted flue vent, a failing inducer motor, cracked pressure tubing, or a ruptured internal diaphragm within the 11177113 switch itself.

Can I test this switch with a multimeter?
Yes, technicians can perform a continuity test while the inducer is running to verify if the switch is closing properly under the required WC (Water Column) pressure.

Is the 11177113 compatible with all Amana furnaces?
No, this is a specific dual pressure switch. You must verify your specific model and serial number against the HVAC parts list to ensure the set-points match the manufacturer's requirements.
