Best 1.5 Microwave Buying Guide

Wattage and Cooking Performance

Wattage determines how quickly and evenly your microwave heats food. For a 1.5 cu ft model, aim for at least 1000 watts. Higher wattage (1100, 1200W) means faster cooking and better results with dense or frozen items.

Models with inverter technology, like the LG Smart Inverter, deliver consistent low-power for delicate tasks like melting chocolate without scorching.

Capacity and Footprint

A 1.5 cu ft interior is large enough for a 9×13 baking dish or a dinner plate, yet the external dimensions vary. Measure your counter space and check the depth before buying.

Some models, like the Toshiba 4-in-1, pack extra features (air fryer, convection) into a similar footprint, making them versatile space-savers.

Sensor Cooking and Presets

Sensor cooking automatically adjusts time and power based on steam emitted, preventing overcooked or dried-out food. This is a game-changer for reheating leftovers and cooking frozen vegetables.

Many top-rated models, including the Avanti and Toshiba 1.2 cu ft (also available in 1.5), include smart sensors. Pre-programmed presets for popcorn, pizza, and beverages add convenience.

Ease of Use and Cleaning

Look for a push-button door release, a mute option for end-of-cycle beeps, and a child safety lock if you have little ones. A removable glass turntable makes cleaning simple. Stainless steel interiors resist stains and odors.

For RV or compact kitchens, consider the Furrion RV microwave, which is designed for mobile living.

Additional Cooking Modes (Convection, Air Fry, Grill)

If you want to replace multiple appliances, a microwave with convection or air fry capability can roast, bake, and crisp. The Toshiba 4-in-1 Combo and Café Convection Microwave offer these functions, though they cost more.

For a dedicated oven-style microwave, the Sharp over-the-range model saves counter space while providing ventilation.

Durability and Warranty

Check the build quality and warranty length. Brands like GE, Toshiba, and LG typically offer one-year parts and labor. Some premium models, such as the Café series, come with a longer warranty.

Verified buyer feedback often highlights longevity issues, so we prioritize models with consistently positive reviews over multiple years.

Frequently Asked Questions

What size microwave is 1.5 cu ft?

A 1.5 cubic foot microwave typically has an interior large enough to fit a 9×13 baking dish or a large dinner plate. External dimensions vary, but most are around 20, 22 inches wide, 12, 14 inches tall, and 16, 18 inches deep. Always measure your counter space before purchasing.

Is 1000 watts enough for a 1.5 cu ft microwave?

Yes, 1000 watts is the baseline for this size. It provides even heating and reasonable cooking times. For faster results, consider 1100W or 1200W models, but 1000W is sufficient for most reheating and defrosting tasks.

Can I install a 1.5 cu ft microwave over the range?

Some 1.5 cu ft microwaves are designed as over-the-range models, like the Sharp R1214TY. These require proper ventilation and mounting hardware. Most countertop models are not built for installation above a stove, so check the product specifications if you need an OTR unit.

What is the difference between a microwave and a convection microwave?

A standard microwave uses electromagnetic waves to heat food. A convection microwave adds a fan and heating element to circulate hot air, allowing you to bake, roast, and crisp.

Convection models like the Café Matte White are more versatile but cost more and may have a larger footprint.

How do I clean a microwave interior?

For stainless steel interiors, wipe with a damp cloth and mild detergent. For stubborn food residue, heat a bowl of water with lemon juice for a few minutes to loosen grime. Always unplug the microwave before deep cleaning.

Many models have a removable turntable that is dishwasher safe.

Are 1.5 cu ft microwaves energy efficient?

Most modern microwaves are relatively energy efficient compared to conventional ovens. Look for models with an ECO mode that reduces standby power consumption. The LG Smart Inverter and Toshiba both offer energy-saving features.
