What is a hard start relay?
In respect to this, how does a hard start relay work?
The start capacitor of the hard start kit is wired in parallel with a normally closed potential relay or PTC thermistor with the compressor run capacitor. Once the circuit is energized, the start capacitor alters the phase angle ( think of it as electrical leverage) between the start and the run winding.
One may also ask, what does a starter relay do? The main function of a starter relay is to work as a switch for the starter solenoid by switching on a large current stream from a smaller one generated from the ignition switch circuit. It does the same for the starter motor when it is an automotive car.
Also know, what does a hard start do?
A hard start kit is an energy-storing capacitor that helps your AC start when it's struggling to turn on. Like their name suggests, hard start kits help solve a problem called hard starting, which is when an AC struggles to turn on and then shuts off abruptly after a short while.
How do you test a hard start relay?
Disconnect the voltage source from the circuit and remove the relay from the circuit. First check the relay's coil by placing the leads of the ohmmeter across the 2 and 5 terminals of the relay. If the ohmmeter reads a high resistance (approximately 3,000 to 18,000 ohms) the coil of the relay is electrically OK.
