The background: recently purchased house with a duel-fuel (gas range, electric oven) stove. Did some renovation work including brand new main (100amp) and secondary (60amp) electrical panels. Electric oven has not worked since we moved in (ie after reno work). Previous owners swear that it worked until the day they moved out and I trust them implicitly, 100%. They actually moved up the street and I see them every day, and I've come to know them, and so I really believe them. So..

Repair guy was here and measured voltage coming out of socket in the wall that oven is plugged into. (It's a jenn-air by the way.) He was able to get 110 on either side, but no reading whatsoever when spanning the two trying to get a 240v reading. Is it possible that the problem is at the circuit panel? Is that where an outlet is made to be 240? Given that that's what's changed since oven stopped working, that's what my money's on, but as is probably obvious, I know next to nothing about electrical stuff. Thanks in advance.
