Purchased this wall oven, love the look, upper oven working great. Lower oven temperature is off by 50 degrees.  I am waiting for the part to have it fixed.  I was told it could be 4 months before the part comes in to get it fixed. Not really happy, brand new and already have problems. I understand quality control does not always get it right, but having to wait to get a brand new appliance fixed, is not acceptable.
