Compatibility & Fitment

• Designed for use in residential and commercial HVAC systems, including air conditioners and heat pumps.
• Suitable for controlling single-phase motors and other high-power loads such as refrigeration equipment, compressors, and resistive heating elements.
• Direct replacement for contactors with matching specifications: 1 pole, 32 Amp or lower rating, and a 24VAC control circuit.

When to Replace

• Outdoor condenser unit fails to start when the thermostat calls for cooling.
• A loud, continuous buzzing or humming noise from the outdoor unit.
• Visible damage to the contactor, including burnt terminals, pitting on contacts, or melted casing.
• The contactor plunger is physically stuck in the engaged (pulled-in) or disengaged position.

Installation Tips

• Disconnect all electrical power at the breaker panel and service disconnect before beginning installation.
• Use a multimeter to verify that no voltage is present in the unit.
• Photograph or label all wires before disconnecting them from the original contactor to ensure correct placement on the new part.
• Confirm the new contactor's amperage rating meets or exceeds that of the original component.
• Ensure all electrical connections are tight and secure to prevent overheating and arcing.
