Panasonic normally uses the CU prefix for outdoor units, so expect this board to sit in the outdoor unit's control box. As with any air conditioner board, it pays to have the fault diagnosed from the error codes before ordering. Have the full model number from the unit's rating label on hand when you check the part.\u003c\/p\u003e\n\u003ch2\u003ePanasonic air conditioner control board faults\u003c\/h2\u003e\n\u003cp\u003eThe electronic control board is the brain of the unit it sits in. It reads the temperature sensors, talks to the other half of the system over the communication wiring, and switches the motors, valves and compressor drive as needed. A failing board can show up as a unit that won't start, an error code that keeps returning after a reset, a fan or compressor running when it shouldn't, or a system that drops out at random. Heat, moisture, insects and voltage spikes from storms are the usual culprits, and scorch marks on the board are a giveaway.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Panasonic part CWA73C5842\u003c\/li\u003e\n\u003cli\u003eElectronic control board (PCB)\u003c\/li\u003e\n\u003cli\u003eListed for model CU-100PE1R5\u003c\/li\u003e\n\u003cli\u003eLicensed electrician or technician to fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eReplacing the control PCB\u003c\/h2\u003e\n\u003cp\u003eTurn the system off and isolate it at the switchboard and the outdoor isolator.
