The electric oven/cooktop that I bought with my house has worked really well (about a year and a half, plus however long previous owners had it), but last week my wife mentioned that the oven won't heat anymore. We played around with it a little bit, and found that while the panel will state that it's heating to a particular temperature (whatever that may be), the element itself doesn't heat up.

This morning I whipped out some tools and started to play around, and here are the measurements that I got..

Element - 16.1ohm
Temperature gauge - ~1.1k ohm
Power in - 244.1v AC (121.9 and 122.5 measured on both legs)

Everything looks within spec, so while I was behind it keeping an eye on things I plugged it back in and had her turn on the oven.. and it worked. Relays clicked on, power on the element jumped to ~240v, and heat started to pour out of the oven! So she canceled it, we waited a minute, and now nothing again. I don't believe it's a power issue, or even a power cycling issue; our power was out the day after we noticed (completely unrelated) and it didn't work after that either.

At this point, I'm leaning towards a new controller board, but the new part is around $300, so I'm hesitant to go drop the cash without asking around a little bit.

Thanks for any advice/suggestions!
