    Not Siemens brand, nor Wking Protech

    Posted by DIY Homeowner on 4th Jul 2023 16:06

    The OEM unit was a Siemens brand contactor. The one shipped was a Zettler Controls brand. Since I'm not in the trade, I don't know if that's better or worse. (The Description says "Upgraded Contractor.)

    The Siemens failed on a lightly used 10 year-old 1 ton only because a black widow spider had infiltrated the relay on the compressor itself, causing the compressor to "glitch" when operating, which burned out the contacts on the main contractor.

    The price for this unit was right. (Last year my local AC Repair shop charged $250 for a capacitor last year. Since I didn't want to be "fooled twice," I Do-It-Myself now.) I give this unit 3 stars simply because I don't know if it will stand the test of time.
