In your HVAC system, the “contactors” are the components or power, that control the flow of electricity from one part of your furnace to another. The contactor sends a voltage into either the heat pump compressor, air conditioning condenser, or condenser fan to inform the system how to operate, and what kind of temperature should be output.

Here at Furnace Part Source, we have a range of contactors to choose from, to help you improve your home heating and cooling experience. Our goal is to ensure that you have one that matches your system’s energy requirements and mitigates potential machine failure.

Multiple Purpose Contactors

Contactors come in a range of different shapes and sizes, depending on your needs. Each one has at least one coil and several contacts.

Air Conditioner Contactors

For air conditioning systems with 115 volts, try out the Carrier HN53CB115 3POLE 25AMP. If you require 120 volts and 200 amps, we can recommend the Copeland 912-3200-01.

Contactors can fail electrically due to issues like being shorted, grounded, or open. Mechanical failure in contactors can occur when pests or debris interfere with the mechanism, preventing proper operation. To check for electrical failure in a contactor, taking a resistance reading between the coil’s terminals is crucial. Contactors have three parts: contacts, coils, motors, and mechanical linkages. A failure in one of these fields may necessitate replacement. Causes can include systems aging over time or overheating, wearing out the components when they have to work beyond their normal means.

Troubleshooting Electrical Failure

In the case of wires and the contact, they need to make contact so as to connect the current. If they get burned or pitted, then they can’t make a connection and the voltage drops dramatically. It’s easy to see if there are burns on the contact; a visual inspection will confirm or deny it. Voltage checks can also help in this regard, to see if there are sudden or unusual changes.

Contactors can also get stuck in an “up” or “down” position; the former cuts off electricity to the rest of the circuits in the system, and the latter provides it. Both are not desirable options; if you have no means to provide electricity, then it means your system can’t function while being unable to turn off the current can waste energy.

Compressor Contactor

In an air conditioner system, the compressor contactor serves as a switch that carries more amperage, controlling power not only to the compressor but also to the fan motors. This highlights the critical role of capacitors in storing enough voltage to power both the compressor and fan motors, emphasizing the potential danger of mishandling these electrical components. A double pole has two contacts within the component, while a single pole simply has one contact. A three-phase commercial unit has three contacts and contactors per electrical component, and as a result, has more amperage than the other two options.

Carrier Contactor

Carrier as a brand always looks forward. They design their replacements for versatility so that they can fit into multiple series. You can even insert some of their components into devices from other brands. We recommend the Carrier 13B0003N01 Compressor Contactor for when you need a smaller part in your system.

HVAC Contactor Replacements

HVAC Contactors are responsible for the insulation and making sure that your system works exactly as it should when you choose a temperature on your thermostat. While the thermostat itself calls for either the heating or cooling process, the contactors are the magnetic components that call for action from the right parts of your heating or cooling system.

Generally, these Contactors come in a single, double, or triple pole. This, along with the voltage and FLA rating, will determine which device is a suitable replacement. FLA refers to full load amps and the maximum current from an inductive load that the capacitor can relay across the contactors.
