The ZLINE MWO-OTR-30 is a stylish microwave that has one of the highest power wattages that we’ve reviewed. It’s one of the more expensive models we’ve tested too so if you’re looking for a cheaper option, take a look at our guide to the best over-the-range microwaves

ZLINE MWO-OTR-30: Features  

The ZLINE MWO-OTR-30 over-the-range microwave has a decent 1.5 cubic feet capacity. That makes it smaller than the LG LMHM2237ST, however, it’s still a good size and bigger than a lot of models we reviewed. 

This microwave does sit with the more pricey over-the-range microwaves, though, at around $600. For that price, you do get a more powerful microwave as this model has 1500 watts of power - most of the models we reviewed have around 1000 watts. 

The ZLINE MWO-OTR-30 also acts as a range hood and its fan has a CFM of 300. That’s pretty average for an over-the-range microwave, however, you can get more powerful fans if you prefer. 

In terms of cooking features, this over-the-range microwave has all the normal functions such as auto-defrost but it also has sensor cooking. This means the microwave will adjust its cooking times according to the humidity levels when you’re using it. That way, you won’t end up with overdone food. There are preset buttons too for vegetables, popcorn, snacks, melting, and more. 

Inside the ZLINE MWO-OTR-30, there’s a DiamondTech interior which is a diamond-effect reflective pattern. This works to cook your food more evenly and make sure no parts of your food are hot while the other parts are cold.

The ZLINE MWO-OTR-30 comes complete with a two-year parts warranty which we think is a little disappointing considering this is one of the more expensive models we reviewed and some cheaper microwaves offer longer warranties.

ZLINE MWO-OTR-30: Design & features 

The ZLINE MWO-OTR-30 might be one of the more expensive models we reviewed but it does look expensive too. Finished in stainless steel, the microwave looks sleek and modern and will fit in with most kitchens. It does, however, only come in the one color option so if you have, or prefer, white appliances, this may be an issue.

The controls on the ZLINE MWO-OTR-30 are smooth, one-touch controls that are positioned up the right-hand side of the model. Some other microwaves have the controls across the bottom edge which may be more favorable. An audible LCD screen completes this microwave. 

ZLINE MWO-OTR-30: User reviews  

The ZLINE MWO-OTR-30 scores an average of 4.8 out of five stars on Home Depot. Users praise the ZLINE by saying that it ‘looks fantastic’ and also mention that it’s easy to use. However, there are some criticisms too. Some users said this microwave was hard to install and a few mention that it doesn’t heat food up very quickly, despite its wattage. Many reviews do mention that this microwave creates a lot of condensation inside the door while it’s cooking.  

Should you buy the ZLINE MWO-OTR-30?  

The ZLINE MWO-OTR-30 doubles up as a range hood and an over-the-range microwave which helps to justify its price tag. Aside from that, this over-the-range microwave looks great and has easy-to-use one-touch buttons, as well as sensor cooking. Despite having 15000 watts of power though, this microwave doesn’t heat food up very quickly.
