Product review (5 stars): Thermostat
Good product.  Easy to install and was used in an electric dryer.  I did learn later than you can take your old one and bounce it on concret about three times and it will reset it self and can be used again.  Apparently, when the unit triggers it is due to over heating.  Once you drop it the action drops back into place allowing you to use the old part.  Something to remember in the future.
