For homeowners who want a dependable, well-rounded microwave that looks great and performs flawlessly day after day, this is the sweet spot. It matches the GE’s versatility while exceeding it in durability and finish.
Choosing the Right Over-the-Range Convection Microwave
Understanding Convection Microwave Features
Over-the-range (OTR) convection microwaves combine the convenience of a microwave with the versatility of a convection oven. Choosing the right one requires considering several features. Here’s a breakdown to help you make the best decision for your kitchen:
1. Ventilation Power (CFM)
The Cubic Feet per Minute (CFM) rating indicates the microwave’s ventilation strength. This is crucial for removing smoke, steam, and cooking odors. Higher CFM ratings (like the 300 CFM found in many models) are better for frequent, heavy cooking, especially if you do a lot of frying or stir-frying. Lower CFM models may suffice for lighter cooking, but may struggle to effectively clear strong smells. Consider your cooking style – if you regularly cook foods that produce a lot of smoke or odor, prioritize a higher CFM.
2. Convection Capabilities
The core benefit of a convection microwave is its ability to bake and brown food like a traditional oven. Look for models with multiple convection settings and a convection rack (included with most options). The presence of a convection rack is essential for achieving even browning and crisping. Some models offer specific convection cooking modes for different types of food (like pizza or cookies), adding another layer of convenience. The ability to adjust temperature settings within the convection mode is also a beneficial feature.
3. Interior Design & Materials
The interior construction significantly impacts cooking performance. Many models feature a stainless steel interior, like the “DiamondTech Interior” found in some ZLINE models. Stainless steel helps distribute microwaves evenly, minimizing cold spots and ensuring more consistent cooking. A glass turntable further enhances even heating by rotating the food. The material also impacts ease of cleaning – stainless steel is generally more durable and easier to wipe down than plastic interiors.
4. Installation & Ducting Options
OTR microwaves can be installed with either vented (ducted) or non-vented (recirculating) configurations. Vented models require ductwork to exhaust air outside, offering superior ventilation. Non-vented models recirculate air through a charcoal filter (often sold separately), which is less effective but easier to install if ducting isn’t possible. Ensure the model you choose supports your desired installation type and consider the cost of any necessary accessories like charcoal filters.
Other Important Features:
- One-Touch Cooking: Pre-programmed settings for popular foods simplify operation.
- Cooktop Lighting: Integrated lights illuminate the cooking surface.
- Finish: Stainless steel, black stainless steel, and other finishes offer aesthetic choices.
- Warranty: A longer warranty period provides peace of mind.
- Size/Capacity: Consider the internal capacity (typically measured in cubic feet) to ensure it meets your cooking needs.
- Air Fry Functionality: Some models, like the GE Profile, include dedicated air fry settings.
- RV Specific Features: For RV use, features like vibration resistance are crucial (Furrion).
