Comparison: Best Microwave Oven Under 4000 (Updated | Dec 8th)

Focus on cooking power (watts), interior capacity (cubic feet), and venting options if you need an over‑the‑range model. Also check for sensor cooking, child lock, and the number of preset auto‑menus, as these affect convenience and cooking results. Finally, consider the fan CFM rating for range hoods and any additional warranty or service plans.

The EM044KB19 offers a 1000‑watt output with ten power levels and a 400‑CFM two‑speed vent fan, while the newer model provides a larger 1.7 cu ft. cavity, 300 CFM vent fan, and multi‑stage cooking options. Both include auto‑cook menus, but the newer unit adds quick‑power shortcuts (1‑3 minutes) for faster meals. The newer model also features a stainless steel finish and a slightly larger footprint.

Countertop models such as the GE 2.0 cu ft. (1200 W) and 1.6 cu ft. (1150 W) units typically cost less and free up cabinet space, offering sensor cooking and child locks at a lower price point. Over‑the‑range units add venting capability, which can replace a separate range hood, but they often have a higher price and larger installation requirements. If you don’t need built‑in ventilation, a countertop microwave usually provides better bang‑for‑buck.

The Farberware 1.7 cu ft. over‑the‑range model delivers 1000 W of cooking power and a spacious interior, making it suitable for larger dishes and family meals. The BLACK+DECKER 1.7 cu ft. model also provides 1000 W but adds a 300 CFM vent fan and multi‑stage cooking, which can be handy for varied recipes. Both are strong contenders, but Farberware includes extra auto‑cook programs that may appeal to busy households.

CFM (cubic feet per minute) measures how much air the fan can move; higher numbers mean better removal of steam, smoke, and odors. For most kitchens, a fan between 300‑400 CFM is sufficient, while larger or more heavily used ranges may benefit from 400 CFM or more. The BLACK+DECKER EM044KB19’s 400 CFM fan offers stronger ventilation than the 300 CFM fans found on many competing models.

Sensor cooking adjusts time and power based on humidity, reducing the risk of over‑cooking or under‑cooking common foods. Auto‑cook menus provide one‑touch settings for specific items like popcorn, pizza, or potatoes, simplifying the process for beginners. Models with both features, such as the GE countertop microwaves and many BLACK+DECKER units, tend to deliver more consistent results with less guesswork.

Standard manufacturer warranties usually cover one year for parts and labor, but several models, like the GE over‑the‑range unit, include a two‑year extended protection plan at purchase. Extended plans can be valuable for higher‑priced or built‑in models where repair costs are higher. Review the terms carefully to see what components are covered and whether accidental damage is included.

A charcoal filter, like the one bundled with the GE 1.6 cu ft. over‑the‑range model, helps keep the kitchen air fresh when using recirculating ventilation, which can be a plus for homes without external ducting. Extended service protection adds peace of mind, especially for built‑in units that are harder to replace. If you plan to keep the microwave for several years and value low‑maintenance operation, these extras can be a worthwhile investment.
