Being a handy EE type, I'm comfortable replacing contactor (and capacitor) in my compressor. Unfortunately, my compressor has developed a habit of going through contactors pretty quickly. Last summer, I replaced it and had to do so again during the same summer. That one just died yesterday. In a peculiar way where it was stuck CLOSED. But now it won't make the connection.
Googling around, sounds like a solid-state contactor might be the solution. But I'm having trouble locating one that has a 24vac input. And not sure that would solve the problem. There's also an expensive mechanical one like this, that sounds like it might solve the problem: https://www.supplyhouse.com/White-Rodgers-49M11-843-SureSwitch-Multi-Volt-Switch-Relay
But I'm wondering if there's something fundamental wrong with the compressor (25 years old) that's causing this.
Thoughts ?
