Wiring in Head Pressure Fan control?

That'll work. Most people would put L2 on 23 though for simplicity. That black wire from 23 to the condenser fan motor would go to "motor 2" on the controller instead of 23.

Cheers!

I like those controllers. Very durable and work exactly as the box says. I would too suspect the old one just died of age or maybe a bit of moisture got inside. It happens.

Don't forget to set your adjustment pots to the same position as the old control. It's partially important for sleeve bearing motors. Ball bearings are more tolerant.

Good luck!

Cheers!
