My son and I watched several videos online using a multi meter to test the dryer and found out the heating element was cracked. We also found too much lint blocking air flow near the lint trap when we took the dryer door off. We bought extra fuses just in case, as well as the element. It was a bit tricky to unscrew because the screw was partially under the metal housing, but we got it in, and the dryer works very well- I think cleaning out all the lint is really important too.
