Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Clock/ timer cannot be seen from the side

Goldminer 5/21/2018

Had the 1813 4 years and it laid an egg. This is the only one that fit in the 1813 space. It is very noisy when in use. Makes terrific grinding noise. It is only 1000 watt so does not perform as well as old one. The light 1813 had 2 is so dim that you need to turn off room light to see whats cooking. The cook area is considerably smaller so things we used to cook in will no longer fit. Its bad

GreenGirl 4/29/2018

We bought the stainless steel one and it is pretty easy to clean like it says. It is also pretty quiet. It cooks the food nicely. It could use another light on the inside though there is only one on one side and the interior is dim. I also wish the outer light that is above the stove was brighter it is near the front though which is better than most.

First want you to know I already own an LG washer and dryer so I am usually very happy with LG products and my microwave is no exception The favorite feature about this microwave is the sensor button which cooks things without me having to know how much time is needed. Love that feature. Plus this is the first over the stove microwave Ive ever owned and I am so happy with the purchase. It has freed up a whole other counter space in my kitchen.
