Hi Gang,
I have a heat pump issue and could use some expert advice please.
I heard a loud squealing noise from outside when my heat pump started up so I knew a motor bearing was on its way out. I was hoping it would last until my next day off but, sure enough after two days I came home to a warm house.
The original motor had three wires... red, black and brown. The new had four... black, white, brown and brown/white. I left the original dual capacitor in place and added a new second capacitor for the brown and brown/white wires. I ran the black to the defrost control board same as the original black. White to the T1 terminal on the contactor where the original red had been. I hope I did that all correctly.
Buttoned it all back up and nothing but a click. I pushed the contactor down manually and the fan and compressor both come on, so at least I know the new motor works. Before I could go any further a sudden thunder storm blew in, I yanked the pull out and headed inside.
When I get back at it I know my first step will be to check for 24 volts to the coil. If I have voltage than that could only be a bad contactor, right? If I don't have any power to the coil than what will my next step be? Could there be a high pressure switch with a reset?
Is there a likely side effect from the failure of a condenser fan motor, or might this just be a coincidence?
Dang its hot in here. :D
Thanks for any info!
