The LG LMHM2237ST is one of the best over-the-range microwaves around. It is also one of the largest capacity microwaves that we’re reviewed so is ideal for family homes or for those that use their microwave to cook food in larger dishes or trays. 

It is priced around the $500 mark though, so it’s noticeably more expensive than some of the other models we’ve reviewed. To find out if we think it’s worth the money, just keep reading. 

LG LMHM2237ST: Features  

The LG LMHM2237ST over-the-range microwave is one of the priciest models in our round up, but for the money, you’re getting some excellent features. First up, the capacity. This microwave is the biggest we reviewed, offering a generous 2.2 cubic feet capacity inside the microwave. 

In terms of power, the LG LMHM2237ST has 1000 watts which is pretty standard and the same power can be found in the cheaper Samsung ME16K3000AS but where this over-the-range microwave differs from others is its fan speed. The LG LMHM2237ST has a fan speed of 400 cubic feet per minute (CFM), whereas most of the others we reviewed offer 300 CFM. The fan also benefits from four different power levels and has been designed to tackle any smoke and odor removal. 

The LG LMHM2237ST features an ExtendaVent 2.0 which is ventilation that’s powerful enough to get rid of cooking fumes and odors from the cooktop below it. This ventilation system has been designed to work quietly so that it’s not too irritating. 

There are 10 different power levels that are operated with touch controls but the real advantage with the LG LMHM2237ST is the Sensor Cook functionality. Sensor Cook technology works by detecting the level of humidity coming off your food. Once the right level of humidity is detected, this microwave will automatically turn off so that your food isn’t overcooked or dried out. Likewise, if your food needs longer before it’s cooked, the LG adjusts accordingly.

For added convenience, there are three settings on the built-in cooktop lighting and there is also an optional energy-saving mode which turns off the display when you’re not using the microwave. This energy-saving mode is quite standard, though, and cheaper models do offer this as well. The sound and turntable can be switched off on this model if that’s your preference. 

The LG LMHM2237ST comes with a one-year warranty on parts and labor, and a 10-year warranty on the magnetron.

LG LMHM2237ST: Design & finish  

The LG LMHM2237ST over-the-range microwave is finished in stainless steel or you can choose a black stainless steel finish instead but it does cost more. Other microwaves including the GE JVM3160RFSS offer a better choice of color and finish options. 

This LG microwave has its controls along the bottom of the microwave rather than up the side. This makes reading and operating the controls a little easier, although the clock is pretty small and can be tricky to read. 

LG LMHM2237ST: User reviews  

The LG LMHM2237ST scored an average of 4.4 out of five stars on Home Depot. Users rated the microwave highly for its roomy interior. Many positive reviews also claim that the microwave is easy to install and the extended panel for ventilation is a real plus. Reviews also highlight features including the ability to turn the sound and the turntable off, how quietly this over-the-range operates, and features such as the softer butter button. 

There were some criticisms too. Some reviews comment on how small the clock is and that it’s hard to read, even when you’re fairly near to the microwave. Another review mentions that the door handle is ‘plasticky and feels cheap’ considering the price that you pay. 

Should you buy the LG LMHM2237ST? 

The LG LMHM2237ST over-the-range microwave is one of the most expensive we reviewed but it also has the most features and the Sensor Cook mode is a real plus. This microwave is stylish and has a powerful fan. There aren’t many color choices though, so if stainless steel or black stainless steel don’t fit in with your kitchen, that might be a problem.
