Product review (5 stars): Turn off the breaker to your oven before you remove the old one or install the new one.
I love it, just not love having to purchase one.  Again.  And again.  Need a new oven, but honestly this element is soooo much more budget-friendly than a new $1,200 oven!  This came in pretty quickly, quicker than the first one I ordered, and these are fairly easy to install.
