How to Pick the Best LG Microwave
Choosing the right LG microwave is about more than just wattage. It's about matching their innovative technology to your kitchen's workflow and your cooking style. From compact solo units to feature-packed over-the-range models, you need to weigh capacity, smart features, and installation type to find the perfect culinary sidekick.
Capacity and Size
The cubic foot capacity dictates what you can cook. A 0.9 cu. ft. model is ideal for singles or small plates, while a 2.0+ cu. ft. unit handles family-sized dishes. Critically, measure your countertop or cabinet space to ensure a proper fit, as dimensions vary significantly even within the same capacity class.
Cooking Technology
LG's Smart Inverter is a game-changer, providing precise, variable power levels instead of the crude on/off cycling of standard microwaves. This leads to evenly defrosted, reheated, and cooked food. Sensor Cooking automates time and power by detecting steam, removing guesswork for common foods.
Power and Performance
Wattage directly impacts speed. Most LG countertop models range from 900 to 1200 watts, with higher wattage boiling water and cooking faster. For primary use, aim for 1000W or above. Over-the-range models, like the 1050W option, balance power with venting duties.
Feature Set and Usability
Consider must-have conveniences. An EasyClean interior has a special coating that wipes clean effortlessly. NeoChef technology offers optimized presets. For OTR models, ExtendaVent 2.0 provides superior external venting. A PrintProof stainless steel finish resists fingerprints.
Installation Type
Decide between countertop flexibility or space-saving over-the-range installation. An OTR model like the 2.1 cu. ft. unit saves counter space and includes a built-in vent hood, but requires professional installation and specific cabinet dimensions.
LG Microwave FAQ
What is LG's Smart Inverter technology?
Unlike standard microwaves that pulse full power on and off, Smart Inverter delivers a steady stream of precise, lower power levels. This allows for gentle defrosting without cooked edges, even simmering, and more consistent reheating.
Is an over-the-range microwave a good vent hood?
LG's over-the-range models with ExtendaVent 2.0 are designed to be effective. The system vents smoke and steam outward, away from the cooktop, and often features multiple fan speeds. For professional-grade venting, a dedicated hood is better, but for most home kitchens, a high-quality OTR microwave is sufficient.
How does Sensor Cooking work?
The microwave has a built-in humidity sensor. When you select a Sensor Cook program, it detects the moisture vapor released from your food as it heats. Once the sensor determines the food is properly cooked, it automatically shuts off, preventing overcooking.
What's the benefit of the EasyClean interior?
The EasyClean interior features a special enamel coating that prevents food and grease from baking onto the microwave's walls. Spatters wipe away with significantly less effort compared to a standard stainless steel interior, making maintenance quick and simple.
Can I install an over-the-range microwave myself?
It is strongly recommended to have it professionally installed. OTR microwaves are heavy, require secure mounting into studs, need proper electrical connection, and must be aligned with your cabinetry and vent ducting. Incorrect installation can be a safety hazard.
