Rated 4 out of 5 by from Great Features We bought this last June and we really like it. It's great at defrosting and softening.

Rated 5 out of 5 by from Spacious and powerful One of the most powerful microwaves out there and after using it a few times, you'll understand why. It works very well, almost too well, so the first few times, make sure you "under" cook things, so you can get used to how powerful this beast really is!

Rated 5 out of 5 by from Really nice microwave! This microwave was part of an appliance package and I couldn't be happier with it. So far it works great, heats fast and is pretty simple to use (as most microwaves are). It has an exhaust fan that slides out and back in located on the bottom part of the micro and just a soft push releases the tray. It's a cool feature that I didn't know I liked until I tried it. And the fan isn't super loud like some fans tend to be. It also has three different lighting levels that are very bright and lights up the stove nicely.

How do you keep the clock display on permanently? It vanishes after about 5 minutes.

Asked by: Jsann
We appreciate your interest in this microwave oven. According to the information in the owner’s manual, the display will automatically turn off after 5 minutes of idleness, depending upon the model. Otherwise, press the CUSTOM SET button, press 2 for CLOCK ON/OFF, and then press 1 for the CLOCK ON selection. If this option is not available, then this will remain as default operation.

What is the rear vent size 

Asked by: Nwood
LG Black Stainless Steel Series 2.2 cu.ft. Over-the-Range Microwave Oven, Model # LMHM2237BD does not have a rear vent. It has an Auto Vent Feature which is an automatic vent fan operation that helps to dissipate heat from your cooktop. When the microwave oven senses an increase in the temperature from the cooktop below, it will automatically turn on the vent fan to create a safer environment for you. During this operation, the scrolling test display on the oven will caution you that the surface beneath is hot by scrolling "Caution Hot Surface". The vent fan cannot be manually shut off during the Auto Vent operation, it will automatically shut off once it determines that the area beneath it has reached a safe temperature...^IFV
