Our 20 yo Whirlpool oven has finally died. We just ordered a Jenn Air double wall oven and I'm trying to decide if the installation is a do it yourself project or if I should pay the $269 for installation. I am fairly competent with basic electrical work (wired my basement refinishing project myself), but don't have any special tools. From what I've been able to read, it's a pretty basic connection process. Do I need any special tools, like a crimper of some sort to make the connections? I haven't taken the old oven out yet to look at the existing connections. It's on a 60A circuit, so I don't have to replace any wire. Any advice would be appreciated.
