Product review (5 stars): Great product
Exact fit for my Whirlpool.  Very easy do it yourself replacement.  Comes with the heater element and housing back-plate.  All you have to do is connect the old thermostat which is easily done.  No special tools required.  Have read of some units experiencing a short life.  This one is still functioning properly.  Would suggest that you ensure the lint ducting is clear in the dryer and exhaust tube prior to restarting operations.  Also as with any high temperature usage items, do not touch the heater element with your hands while completing the replacement.  I suspect the transfer of body oil that happens may be a cause for some of the short life problems.
