I think I would still check the start capasitor in both units. This may not make a lot of sense but here is what I found last summer. My rear unit had quit cooling, most of the time, but now and then when I reset the breaker it would work. I found that the start capasitor had rusted and there was a path from one of the contacts to the AC case. This caused the voltage to the the reversing relay (Changes unit function from AC to Heat Pump) to be around 78 volts instead of the 110 needed to engage the relay. I replaced the start capasitor and cleaned up the rust now everything is working fine.

Eddie, if it happens again, remove the interior cover of the A/C unit and unplug the phone cord style connector and then reconnect. Do this with either the air on or thermostat on in A/C mode. Just another reset option.
