Convection Microwave Buying Guide
Size and Capacity
Convection microwaves range from 0.9 to 2.2 cu. ft. Larger models (1.5+ cu. ft.) fit whole chickens and large casseroles but take up more counter space. For most households, 1.0-1.5 cu. ft. is ideal. Measure your counter depth and ensure at least 3 inches of clearance on all sides for ventilation.
Wattage and Cooking Performance
Microwave wattage affects reheating speed: 900W is adequate, 1000-1200W is better for quick cooking. Convection wattage (1000-1500W) determines browning and baking. Sensor cooking adjusts time based on humidity, which helps avoid overcooking. Inverter technology (Panasonic) provides steady power for gentle defrosting and simmering without hot spots.
Key Features and Build Quality
Look for a removable turntable for easy cleaning, a child lock for safety, and preprogrammed settings for common foods like popcorn, pizza, and baked goods. Stainless steel interiors are more durable and easier to clean than painted ones. Check user reviews for complaints about noise, button sticking, or uneven heating. Avoid models with many reports of early failure.
Safety Notes
- Always use microwave-safe containers. Metal and aluminum foil can cause arcing.
- Keep the microwave clean to prevent food fires. Wipe spills immediately.
- Do not operate when empty; it can damage the magnetron.
- Ensure proper ventilation: leave at least 3 inches of space around the unit.
What to Avoid
- Daewoo KOR-6L0B: small capacity, uneven heating, and many reports of failure within a year.
- Commercial Chef CMO-1001S: low wattage and poor convection performance.
- Avanti MCOB-0900S: flimsy door latch and noisy operation.
- Galanz GLOMKA17SDR: inconsistent sensor cooking and short power cord.
FAQ
Can I use metal pans in a convection microwave?
Yes, but only in convection mode. Never use metal in microwave mode. Check the manual for specific guidance.
How does convection microwave cooking differ from regular microwave?
Convection adds a heating element and fan to circulate hot air, allowing browning, baking, and roasting. It cooks food more evenly and with better texture.
Do convection microwaves need special cookware?
For microwave mode, use microwave-safe glass or ceramic. For convection mode, metal pans are okay, but avoid plastic. Always use oven mitts as the cookware gets hot.
Final Verdict
The Toshiba EC042A5C-SS is the best all-around convection microwave with reliable even heating and sensor cooking. For those who want gentler, more precise cooking, the Panasonic NN-CD87KS is a top alternative.
