Question about Panasonic CS-A12C Air Conditioner
Sounds like your contactor has welded shut. Everytime your condensing unit turns on, you'll have a an arc of electricity across the contactor. Over time, the arcing causes to contactor to become covered in cardon. When it gets to a certain resistance across the coil, it will weld shut and the comressor and outdoor fan will run forever until the bad contactor gets replaced. If you know what a contactor is, it's a simple fix and the price is about $20 bucks. If your unsure about replacing it yourself, by all means can an HVAC contractor to replace it. 240 volts is not something you want to mess with unless you know what you are doing
