What Do HVAC Contactor and Starter Parts Do?
First things first, it’s important to have a general understanding of what your system needs. In terms of heating and cooling equipment, contactors and starters are two types of electrical components that play important roles in controlling how the system’s motors, compressors, and other electrical devices operate. To put it simply, they help manage the flow of electricity. This means that they are responsible for the start-up and shut-down processes connected to various HVAC system components. So if you’ve narrowed down the problem to the system not even starting up, then your HVAC contactor might be to blame.
HVAC contactors are crucial components for HVAC systems because they’re in charge of the motor functions through the power supply. For example, if the thermostat calls for cooling, the contactor works to allow electricity to flow to the compressor, which then starts running. Once the set temperature is reached, the system will stop cooling and the contactor will de-energize, or turn off that power supply to the compressor.
Sometimes issues pop up just from the HVAC contactors. Other times the problems are related to the HVAC motor starters. These are usually made up of their own contactor and control circuit, along with an overload protection to ensure smooth acceleration with the motor’s current. That way, if there’s a mechanical issue or problem with an excessive current, the overload protection will trip and interrupt the motor’s power supply to help prevent damage to the system.
HVAC motor starters are typically used in larger applications that require industrial-powered motors, whereas HVAC contactors are found in all types of HVAC equipment. But no matter whether you’re looking for commercial-grade replacement parts or something to suit a residential heating and cooling system, you’ve come to the right place!
