There is no one-size-fits-all answer to this question, as the necessary skills and tools required to install a microwave oven may vary depending on the model and brand. However, in most cases, installing a microwave oven is a relatively easy process that can be accomplished by most homeowners with basic DIY skills. Before installing a microwave oven, it's important to consult the owner's manual and ensure that you have all of the necessary tools and parts. Many microwave ovens come with installation kits that include everything you need, including screws, brackets, and seals. If your model doesn't include an installation kit, or if you're missing a few key pieces, then you'll likely need to purchase them separately.

It depends on the microwave. Most microwaves come with installation instructions, and most people are able to install them without too much trouble. However, if you're not comfortable installing the microwave yourself, you can always call a professional to do it for you.
