I have a 10 year old AquaComfort AC1250 heat pump. I just went through the repair/replace decision, and for now I'm still trying to repair. So far the heat pump is winning.
The 24-volt transformer, which powers the control board and, through the control board, all relays and sensors has a built-in breaker that trips as soon as I power up. I have replaced the transformer and the control board. One at a time I have disconnected all relays and sensors from the control board (both wires, in case something is shorting to ground), but the breaker still trips.
I'm getting 242-244 volts from the power company, but that is within spec for them.
Does anybody have any experience with this kind of problem, probably in your "Dang, That's Weird" file?
Thanks.
