This dryer is an exact replacement for the same model that I have owned for years, but thought had died when it would not turn on, even after pressing the reset button. What I failed to do was read both the printed directons (long ago misplaced) and the engraved instruction (see photo) that are molded onto the front of the saftey plug. After following the instructions that came with the new dryer, my old dryer came back to life. What did I do wrong? 1. I failed to UNPLUG the drier and be sure it was cool BEFORE replugging it in. 2. When I plugged the dryer again, I failed to press the Test button, BEFORE pressing the Reset buton. Failing to do so the reset button wouldn't work. Correctly pressing the yellow reset button first, caused the blue reset buton to click fully out and operate. Although I personally don't usually take the time do this, the instructions molded onto the saftey plug advise you to press the yellow test button EVERY time you plug it in. When you do this, you should hear the blue reset button click outward. Now press the reset button and the dryer should work. On the other hand, should you press the test button and see, while doing so, an LED, located just above the test button, momentarily flash, your dryer has developed an electrical fault. A cause for this might be pulling the cord out too far, beyond the red line on the cord and putting traction on the internal end of the cord. (This did happen to me.) If so, retract the cord to the red line and press test again. Hopefully it no longer will flash when you push test again. If it doesnt flash, it safe to then press reset and use the dryer. However, if the LED still flashes, there is a more permanent electrical problem. Then DO NOT press reset and attempt to use the dryer again. (My older Conair dryer, which I am now keeping for a back up, doesn't have this LED test light on the plug.) BTW, if you follow the instructions EXACTLY, you shouldn't have any problems with the recoiling of the power cord, even after years of service. Do NOT press the recoil button and expect the cord to quickly wind itself back into the drier. It won't. You must press the red retract button and hold it down, while you hold the cord and feed it SLOWLY into the drier. This means you have one hand holding the drier and the button, while your other hand is holding and feeding in the cord. It works almost every time. If it doesn't, and you have done all this, it could be that the cord was not pulled out sufficiently to created the tension needed on the spring that does the recoiling. . (There is a red mark on the cord to show how far to extend the cord .) If it doesn't work on a first try, just pull the cord out again, and repeat, being sure to feed the cord slowly back in. There have been complaints that this feature didn't work or failed to work after a while. I am guessing people were just pressing on the buttom and letting the cord attempt to fly quickly into the drier. It will, but only partially. Perhaps, this damages the mechanism over time. My new drier's cord recoil strength is just as good as my old drier. While I haven't had the new one years, I can't imagine it won't hold up as well. The only difference I can see between the new and old drier, besides the LED on the saftey plug, is the place of manufacturing. The new one is made in Cambodia, while the old one was made in China.
