Which mode did you use: regular cooking or sensor cooking?

I am using regular cooking, not sensor mode.
By the way, thanks for all your help so far. It's great to learn how to fix something new.

Hi Sean,
It took a few days to do more search. Since you already replaced the control board once, you may have gotten a bad one, but my guess is you've got a wiring problem, and the voltage is dropping out under a load.

I was wondering if a solution was ever found for this problem. I have one that's doing the same thing. I've replaced the control board twice and it has made no difference. The relay that energizes the magnatron engages and immediately switches off when I first start the microwave. If I open and close the door the relay engages and works normally when i restart the oven. If I set it for 90% power it works also works fine. Even at 100% power when the microwave cycles after the first minute the relay engages and stays energized.
This seems like it has to be a control board issue but I don't think it's at all likely that I received two bad boards. There are a number of mentions of this problem on various sites so I'm hoping that somebody has found a solution.
