Amana-Goodman CONT3P040024VS Contactor

The Amana-Goodman CONT3P040024VS is a purpose-built 3-pole HVAC contactor engineered for heavy-duty switching in commercial and residential condensing units. Designed to manage high-amperage loads, this 40 amp 24V contactor features durable silver cadmium oxide contacts to prevent welding and pitting under high-cycle conditions. It is a direct OEM replacement contactor for Goodman, Amana, and Janitrol systems, ensuring precise footprint matching for faster field installation. The 24V coil voltage is optimized for standard low-voltage control circuits, providing reliable pull-in and drop-out performance even during transient voltage fluctuations. As a three-pole definite purpose contactor, it facilitates the simultaneous switching of all three phases, making it essential for three-phase compressor and fan motor applications. Utilizing this Goodman certified part maintains the mechanical integrity of the electrical cabinet and ensures the inductive load remains within manufacturer specifications for long-term system reliability.

• Industrial Build: Rated for 40 full load amps (FLA) to handle high-torque compressor startups without contact degradation.
• OEM Compatibility: Exact drop-in replacement for Amana and Goodman HVAC parts, reducing the need for field modifications.
• Enhanced Durability: Dust-shielded design protects the magnetic coil and mechanical linkage from debris common in outdoor environments.
• Secure Terminals: Equipped with heavy-duty lug connectors and spade terminals for high-integrity electrical pathways.

Common Questions

Can this 3-pole contactor replace a 1-pole or 2-pole model?
Technically, a 3-pole contactor can switch fewer phases, but it is best practice to match the CONT3P040024VS to the original system design to ensure proper crankcase heater operation and safety limit integration.

How do I verify if the 24V coil is failing?
Check for continuity across the coil terminals (A1-A2). If the coil shows an open circuit or if there is audible "chatter" despite receiving 24VAC from the transformer, the contactor requires replacement.

What causes the contacts to pit on a 40 amp contactor?
Frequent cycling caused by low refrigerant pressure or thermostat issues increases arcing. Using a high-amperage HVAC contactor like this model helps mitigate heat buildup during these events.
