Don't EVER buy an appliance from LOWES and other

[Tink]

Sorry to hear of the royal screw you are getting thus far. If "all the lights are on, but nobody's home", it may be the wire on the safety lockout has disconnected, as that is what happened to mine years ago (older model). The switch is in the door, and my numerous slamming the door shut dislodged it from the switch. All the tech did was pull the front skin, exposing the switch, found the disconnected wire, "tightened" the spade terminal on the end of the wire, re connect and put the cover back on.
I know you are still under warranty, so you may not want to investigate, but if push comes to shove...
