Product review (5 stars): Replacing old Whirlpool Combo
I was looking for reviews on this combo and was not finding exactly the information what I was looking for, thought this might help someone!

I purchased this PT970SRSS to replace my 18 year old Whirlpool microwave oven combo. I had multiple challenges, the height of any combo today is much shorter than what I had so I needed to build up the bottom or buy separate units that can look like a one unit which would close the 4" gap in the bottom to about 1" and I went and purchased a separate GE Microwave and Oven with the stainless steel trim kit which was a nice solution, after I pulled the old one out, I had a different problem. There was no 110V for the microwave in the cabinet. In a one unit like my old one and this one PT970SRSS, it is a one cord that connects both microwave and oven vs. separate units where the microwave runs separately on a 110v line and the oven is on 220/240v which I had. I took everything back, since I am not going to run a 110v to the cabinet and damage all kinds of tiles walls etc. Then I purchased this PT970SRSS online for 2k with 5 years warranty. I had to build a 4" increase to the bottom of the cabinet which was a lot easier than running 110v. This oven combo comes packaged very well and with very clear instructions, I have never installed a wall oven before and worked very well for me, the one challenge I had is lifting into place, my 14 year old son helped me. Remember once you remove the oven door, and racks, turntable, it is about 150lb which is not too bad.

Observations: - Very quiet operations, the microwave is very powerful and very quiet. - the oven: I thought that the fan would be noisy and was very surprised how quiet it is for such a large convection fan. Heats a little slow, but, cooks much faster than my old oven. on 400 degree. I placed two frozen pizzas on two racks and both cooked well, for about 15 mins. - I like this one better than the non-profile; the oven door's glass is really dark unless you turn the light on. Looks real nice. One thing that I thought kind of odd, it has two clocks that you have to set separately, the interesting thing the bottom clock does not ask you for AM/PM unlike the top one! design flaw?. - I had good luck with GE in the past and I am sure there will always be parts for it.

I purchased 48 months warranty on top of the the GE 1 year for the simple fact that the microwave will definitely die before the oven, which is what happened to my old one, I am sure that will use the warranty.

I am very happy with the initial quality.
