Rated 3.5 out of 5 by 4 reviewers.
Rated 2 out of 5 by Cracked door at handle I had this microwave installed in '04, and for the past 2 years, I have had a cracked door. I tried touching it up and sealing it, but now, if it gets dirty, I can't clean it because it would mess up the paint touch up. This has been very annoying. I compared it to a friend of mine's microventhood, and hers is made out of metal like a stove, but this door on mine is PLASTIC! That's got to be the problem. I contacted the company and they would do nothing. I will NEVER buy their products again! 9/2/10
Rated 4 out of 5 by Same Cracked Door Except mine separated completely. It's on the lower edge and runs from the bottom to the window. Replacement part is $90 discounted. 4/17/11
Rated 4 out of 5 by You get what you pay for. I've had this microwave for 7 years and it has worked like a charm. However, I too had a crack in the door from the bottom of the handle going up toward the glass. This happened after 1 year. I believe the screw in the handle was tightened too tight from the factory causing the plastic to crack. I had a fire on my stove that melted the plastic handle and door. It will cost more to replace those parts than buying a new microwave. The microwave still works--just ugly. 10/21/11
Rated 4 out of 5 by Good purchase The only problem I have with this unit in the crack on lower door in plastic . The door never seemed to close wright from day one . Over all the unit works well recommend 10/20/13
