Product review (2 stars): NOT a good idea
I purchased this on Oct 29th 2012 and installed it the day before Thanksgiving 2012. (Everything breaks around my house just before the holidays) Less than 2 years later on Oct 14th 2014. I came home to the unit humming like it was on. I opened the door and put a cup of water in it and closed the door. Sure enough, it heated the water! No button pressing necessary!!!  From what i understand, the control board has failed as one of the relays or a Triac has shorted out in the on position. To me this is a huge safety hazard to have your micro turn on by itself!!The control board is $190 plus shipping and tax. That is doing it myself. add another 180 to have it done. 1 trip to diagnose and 1 trip to replace part. I paid 219 delivered for the micro brand new !!!.  I contacted Frigidaire via their website, they have not replied in over 8 days. Why should they? it has a 1 year warranty and that is fine by them. I did not purchase the 2 year home warranty, I wish i had. But with my luck it would have simply waited a couple days after that and failed. The fact that Frigidaire does not even bother to respond has me more upset than necessary.  If it was a counter top unit, i would not complain so much. But these things are all unique and require time to install properly.  My old Kenmow lasted 7 years, replacing that was a no brainer. .  When it worked it worked, that's why i give 2 stars
