Amana-Goodman B1370772SP Relay

The Amana-Goodman B1370772SP Relay is a critical OEM time delay cycle protector engineered for Amana and Goodman HVAC systems. This 180-second delay relay is designed to prevent short-cycling, protecting the compressor from premature failure due to rapid power interruptions or thermostat fluctuations. As a direct HVAC replacement part for legacy models B1370772, C6415502, and 7033, this component ensures exact electrical specifications and terminal positioning for field installation. By maintaining a precise three-minute delay window, the B1370772SP allows system pressures to equalize before the compressor restarts, reducing high-amperage locked-rotor-amp (LRA) events. Technicians typically utilize this Goodman time delay relay in residential and light commercial condensing units and heat pump applications where reliable sequence timing is mandatory for operational stability.

Key Benefits for Contractors

• Direct OEM Matching: Replaces B1370772, C6415502, and 7033 without the need for mounting modifications or terminal re-pinning.
• Compressor Protection: The 180-second cycle protector prevents damage from short cycling, ensuring the system remains off long enough for refrigerant pressures to balance.
• Universal Compatibility: Works across a wide range of Amana and Goodman HVAC systems, making it a standard stock item for service trucks.
• Optimized Sequencing: Improves HVAC system sequencing by providing consistent, factory-calibrated timing that meets original equipment specifications.

Common Questions

What is the purpose of a 180-second delay on this relay?
The delay ensures that if the system loses power or the thermostat cycles quickly, the compressor does not attempt to start against high head pressure, which protects the motor windings and capacitor.

Can I use the B1370772SP to replace the older B1370772 model?
Yes, the B1370772SP is the direct OEM replacement for the B1370772 and is built to the same form and function standards.

Is this relay compatible with non-Amana/Goodman brands?
While designed specifically for Goodman and Amana HVAC systems, the technical specs may allow for cross-application; however, it is recommended to stick to the manufacturer's specified part numbers for safety and performance.
