Two broke within 3 years - Unreliable and Expensive
T. Brewer, Amazon
12 June 2013
Summary: I bought a new home with one of these pre-installed. It lasted 15-months, then stopped working with a loud "pop". I replaced it with a new one and it too stopped working with a "pop" after 14-months. Perhaps I'm naive to think a microwave this expensive should last two to three years, but I'm done with Whirlpool. Hello, Panasonic.
Summary: Although the description says 1100 watts, mine states it is 1200 watts inside the door. Also, my model is the stainless steel and metal casing (not sure where the all-plastic junk is at that people are talking about, unless there is a lower-end model with same mt4155sps5 model#) Heats great/fast, love the "Jet Start" button... happy so far!
Summary: The microwav was what I expected. Except there were dings & dents on the microwave and, specifically, the stainless trim was of poor quality. I believe this was reboxed by the seller and then sold again as it looked as if it had been a previous return. Either Whirlpool or EvVive, or both, need to improve their quality control. However, it was easy to return and I was told today I will receive my full refund.
Summary: I bought this unit based on good reviews here and on Consumer Reports. I was very disappointed. I am sending it back, despite having to eat the shipping costs. I should have suspected things weren't going to go well when I found a cigarette butt tucked into the plastic bag containing the manual. But I went ahead and installed the unit in my cabinet, using the recommended trim kit. The oven and the trim kit were both stainless steel, but did not match each other.
Summary: As you know, re-modeling a kitchen can be very costly. Having spent mega-bucks on a total renovation, we looked to save money where we could; the appliances. We were not willing to sacrifice function, looks, or affordability. The Whirlpool MT4155 microwave meets our demands. At 1.5 cu. ft. capacity, I can cook in large casserole dishes. The 9"x13" glass pans fit in there comfortably, also. This is a powerful unit and performs quite well.
