Product review (5 stars): Reliable part...buy it.  Save yourself some money.
Watched a YouTube video and did a little trouble shooting and fixed my dryer with this timer.  Cost was around $60 with shipping.  Dryer works great...going strong.  Took all of 15 minutes to install.

Just FYI,  there is a trouble shooting chart / schematic in the back of your dryer, behind the top panel, where the timer is located.  It's taped down.  That's what the video said, and that's where I found mine, and used it to trouble shoot my dryer timer.  It was bad.  All you need is a cheap volt / ohm meter, or an even cheaper continuity checker and a 1/4 inch nut driver to remove the back panel.  Took out two or three screws and unplugged two connectors to remove the timer...reversed the process for installation...and bingo...there you go.  Tested the timer by selecting a dryer setting, and once satisfied that it worked,  replaced the back panel.

Highly recommended.
