Product review (3 stars): Works fine so far.
Be sure to replace both of the thermostats at the same time.  Usually the operating thermostat fails and the dryer then cycles on the high-limit thermostat until it also fails.  So, if the high-limit has failed, it is pretty certain that the operating thermostat is also shot. The parts I received were NOT genuine Whirlpool, contrary to what the ad says.
