After my Kirby's fan melted from using a small nozzle (which can inflate balloons), I called Kirby to find out how much the repair would cost. After being quoted a ridiculous amount, I did a little research on YouTube and decided to solve the problem myself. I received the fan in the mail, disassembled the vacuum cleaner following the steps in the video and replaced the worn parts with parts from the kit. It's been almost a year and the vacuum cleaner is still working with no loss of performance!
