It's the circuit board in the outdoor control box that runs the outdoor side of the system and exchanges signals with the indoor unit. The A at the end of the model number matters, as revisions of a model can use different boards. Read the model off the outdoor unit's rating label and compare it before ordering.\u003c\/p\u003e\n\u003ch2\u003eSigns of a faulty Panasonic outdoor PCB\u003c\/h2\u003e\n\u003cp\u003eSitting outside through summer heat and winter rain, the outdoor board controls the compressor, outdoor fan and other loads based on its sensor readings and commands from the indoor unit. When it fails the system may blow cold air in heating or warm air in cooling, show communication or outdoor errors on the controller, trip the breaker, or refuse to start the compressor. A visible scorch mark, a bulging capacitor, a burnt smell or signs of an ant nest inside the box all point to board damage. A technician should check the sensors and wiring too, since faults there produce similar codes.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Panasonic part CWA73C8181\u003c\/li\u003e\n\u003cli\u003eOutdoor unit printed circuit board\u003c\/li\u003e\n\u003cli\u003eListed for the U-125PE1R5A outdoor unit\u003c\/li\u003e\n\u003cli\u003eHard-wired equipment, licensed fitting required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitting the outdoor board\u003c\/h2\u003e\n\u003cp\u003eWork on outdoor boards should be done by a licensed electrician or air conditioning technician. Isolate the supply, then wait for the capacitors to discharge and test for zero volts. Photograph the plugs and terminal wiring, transfer everything to the new board in the same orientation, and seal the control box against insects afterwards. Clear the error history and run the system in both cooling and heating.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eWill this board fit a U-125PE1R5 without the A?\u003c\/h3\u003e\u003cp\u003eNot necessarily.
