I bought this just a little over a year ago. Used it on holidays. Had to use this morning as our oven messed up last night. Plugged this in and the power wont stay on. So aggravated as I paid quite a bit for it to only use it 3 times...Any suggestions on what it could be? The clock still displays but it won't do anything else.  I would've gave 5 stars before this morning as it worked perfectly before
