In your HVAC system, the "contactors" are the components 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, or air conditioning condenser 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.
The contactor sends a voltage into either the heat pump compressor, or air conditioning condenser to inform the system how to operate, and what kind of temperature should be output. In short, they control your power supply and where the energy travels to which component. Here at Furnace Part Source, we have a range of contactors to choose from, to help you improve your home heating and cooling experience.
HVAC contactors are responsible for 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.
Contactors come in a range of different shapes and sizes, depending on your needs. We recommend the Carrier 13B0003N01 Compressor Contactor for when you need a smaller part in your system.
Contactors have three parts: contacts, coils, 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.
In the case of 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 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.
