I wanted to title this: Outside unit running, but thermostat is off but I'm 99% sure its the contactor unless someone here says otherwise.
Thus my real question: which contactor should I buy? I typed in the part no. on Amazon but I'm experiencing death by choices. No where on my current contactor can I find the words 1 pole or the amperage. The variety of contactor choices I have are making me nervous. Heres the pic of my current one
One last question, does manufacturer matter? Do I buy Siemens only?
Everything works fine by the way the fan just runs non-stop. Just fyi I've replaced the capacitor and a fuse on the control board this week.
