my power adapter was overheating . for the last 3 day . now the power won’t come one at all . went to a apple store they tell me it will coast $ 299 to repair . can the power supply be change or repair ? can’t the 3tb drive be salvage for something ? Update serial C86L6FXRF9H5 WHERE CAN BUY A NEW POWER SUPPLY ?
Given how easy this system is assembled there is no direct guide to replace the power supply. Here’s the the IFIXIT teardown: AirPort Extreme A1521 which is the exact same unit as the A1470 hardware wise. As to the power supply you’ll see in in Step 13. But before you go there I suspect your real problem is the fan unit seen in Step 12 and the buildup of dust. I would start there clean the dust out if you haven’t already and carefully test out the fan making sure its working. Here’s the Power Supply part: eBay: ME918 Power Supply
