    Can we have something better than the user manual?
    I have just had a new kitchen installed and Westinghouse oven and microwave, which look fantastic. I have no problem with the main oven, which I had in my home before I moved and liked it so much, I purchased another for my new kitchen. However I have no clue how to use the microwave, other than to just use it as a microwave. It has all these fancy functions and no real explanation as how to make the best use of them. What I really need is some type of Westinghouse microwave oven cook/recipe book to explain the best way to use all these functions. The user manual just doesn't cover much and is hard to understand.

    Great size and features
    Had 2 of these ovens installed and they are fantastic. Great size, loads of functions, super easy to use and love that they can be used for steam assist cooking. Best oven I have had so far.

    Questions & answers

    I need to buy a new microwave but urgently want to buy an intergrated one and use it as a stand alone one till my kitchen is renovated can I do this? Cazza · 2019-04-06
    Good morning, Thank you for this question, being integrated these models require a shelf that will lift the microwave up so that the door will be able to open, if you notice in the images provided you would have to lift the item up so when the door was opened it does not damage the bottom of the door or your benchtop, these are not designed as a freestanding product they are designed for built purpose only, maybe purchase the item and store it till your ready so it's ready when your kitchen goes in. But if you need something just to to do you for now maybe a small freestanding model until your kitchen ready to go in there are models available around $132.00 which will reheat and defrost. i hope this information will assist you when shopping here with us at Appliances online.

    Can regular flat pullout trays be bought separately? It seems to have the supports up the inside walls to slide them onto at two different levels? Or does it only come with the round grill trays seen in the video? Thanks in advance. mrjudsonjames · 2017-11-07
    Yes, I agree with you, however, this item is only made with the turntable accessories as per the video. There is no option for any slideout shelves from the supplier. colin.jones, Appliances Online
    Does this have a turntable like conventional microwave? bruceyeah · 2017-04-10
    Hi there, Thank you for your enquiry, Westinghouse has advised this particular unit definitely does come equipped with a turntable. Please see page 12 of the User Manual (Specifications tab) for further information regarding the turntable.
