Watch a few youtube vids on how to install this product.  One video for example has you dismantling the entire dryer, drum and all  to get to the heating section. I was fortunately familiar with that since I had already replaced my rollers before, and realized I did NOT have to do that on my unit. Rather, another video gave me the clue that I could access everything simply after removing the front panel and reaching through the bottom right. It still took some disassembly . but was way easier than removing the top and entire drum. lol.
