Product review (5 stars): Genuine product and fairly simple to replace
Relatively simple fix with help available on youtube and search engines. Not a long job even for someone not an electrician. Just make sure you take a picture of the original fittings so you can replace it easily and not worry about which wire goes where. Another chunk of money saved over a repair call/

Genuine part arrived in Whirlpool bag. If it is not genuine it is a darned good fake!

I think the people suffering from failed ones  is a result of a clog in the exhaust vent duct or at least for some of the cases. Clogging leads to heat build up and failure of the thermostat.
