All has been fine since the last day I posted. I ran the micro wave off another outlet for dinner and had no issues, so after the things I read here and online, I concluded the issue was the original installation by the person who wired that outlet or possibly the receptacle.

I replaced the receptacle and the plug and all has been fine.The first couple of days I even would go up and feel the plug for any heat but there is none.

thanks again!!

PS. I do keep an eye on it, just not as often as after installation

Thanks for the update, I have checked ours also, so far no indication for problems. Guess the installer was having a bad day.
