Size depends on the family size and typical use. For a family of 1-2 we suggest microwave capacity of 0.7 cu. ft. – 1.0 cu. ft. as the unit will allow typical use of day-to-day essentials like reheating single-serving meals and ingredient preparation. For a family size of 2-4 we suggest 1.0 cu. ft. - 1.6 cu. ft. as the typical use is for reheating dinner plates and cooking medium sized dishes for family meals. For 4+ people, we suggest 1.7 cu. ft. - 2.2+ cu. ft.as you will be able to defrost, cook and reheat large or multiple dishes at once. Learn more about our section here.

4.    What microwave is most energy efficient?
Inverter microwaves are recognized for their lower power consumption because they operate at a consistent energy level. This energy-efficient design makes them more efficient than traditional microwaves. The SHARP microwaves with  inverter technology, include the SMC1464KSC, SMC1664KSC and SMC2264KSC which reliable convenience and are an excellent choice for your cooking needs.

5.    What are the safety precautions for using a microwave? 
All countertop microwaves should be positioned at eye level or lower, at least 1 metre or 3 feet away from any combustible materials, and kept clear of any objects that obstruct air circulation or block air vents. Do not operate the unit when it is empty or use it for storage. Avoid using the oven if the door does not close properly, is bent, or if the seal, hinges, or latch are damaged. Do not tamper with the safety interlock switches or the fuse. The microwave will automatically turn off when the door is opened. Never leave a running microwave unattended and try to avoid standing directly in front of it for extended periods. All SHARP microwaves come with a Child Lock enabled to prevent accidental opening and touching of hot food and beverages. The Child Lock may be disabled if it is not required in your household.

6.    What precautions should be taken when using a countertop microwave? 
Use the microwave only for heating food or beverages, or other approved uses. Avoid using metal-edged bowls, metal plates or cups, tin foil, or metal twist ties, as these can spark, damage the unit, and cause a fire. Only use materials that are labeled as microwave safe. Always read the cooking instructions on the packaging. Puncture cooking pouches and foods with tight skins to allow steam to escape during cooking. Do not permit children to use plastic cookware without complete supervision.

7.    What are the pros of a microwave oven? 
Microwave ovens are quick, making them more energy-efficient compared to other cooking methods. Additionally, since they do not require preheating like conventional ovens, they can heat food rapidly while conserving energy by avoiding the need to warm up empty space in the appliance.

8.    What should never go in a microwave oven for safety reasons? 
The following items that should never be placed in a microwave oven for safety reasons:

  • Metal Objects: This includes aluminum foil, metal pans, and utensils, as they can cause sparks and fires.
  • Non-Microwave-Safe Plastics: Containers not labeled as microwave-safe can melt or release harmful chemicals when heated.
  • Sealed Containers: Foods in sealed jars or containers can explode due to pressure buildup.

9.    Which is better, a grill or a convection microwave? 
It comes down to your cooking style and preferences. A grill microwave is ideal if you primarily want to quickly grill and crisp food. In contrast, a convection microwave offers a broader range of options for baking, roasting, and grilling, making it a versatile alternative to a traditional oven with multiple cooking modes. We recommend the SHARP SMC1585KS 1.5 c.u. ft. 900W convection microwave.

10.    Which is better, solo or convection microwave? 
The best type of microwave depends on your cooking style and what you plan to prepare. A solo microwave is if you need a straightforward appliance for reheating and basic cooking. If you opt for a convection microwave if you are wanting versatile and the ability to bake, roast, grill along with other microwave functions. 

11.    Why do microwaves have 3 door switches? 
Microwaves typically have three door switches for safety and functionality. The first switch ensures that the microwave does not operate if the door is open, preventing accidental exposure to microwave radiation and potential injury. The second switch engages when the door is securely closed, allowing the microwave to operate. The third switch may serve as a backup or part of an interlocking system to confirm that the door is properly aligned. Together, these switches enhance the safety and reliability of microwave operation.

12.    What is the difference between an inverter and a convection microwave? 
A convection microwave combines microwave cooking with convection heating, allowing for versatile methods like baking and roasting, making it ideal for achieving a crispy texture. In contrast, an inverter microwave uses continuous low power for more precise and even cooking, particularly beneficial for defrosting and reheating delicate foods. Your choice between the two depends on whether you prioritize versatility in cooking styles or precision in temperature control.

13.    What type of microwave is best? 
The best type of microwave depends on your specific needs, cooking preferences and budget. Countertop microwaves are ideal for routine use, as they are easy to set up and come in many sizes and power levels, making them suitable for small kitchens. Built-in microwaves, such as SHARP’s microwave drawer line-up saves counter space and provide a sleek, integrated look, often featuring advanced capabilities and convenient placement. Over-the-range microwaves serve a dual purpose by acting as a range hood, which is beneficial if you have limited counter space. For those who enjoy cooking a variety of meals, convection microwaves combine microwave and convection cooking for baking and browning. Inverter microwaves offer more precise cooking and defrosting by providing a steady stream of power, making them perfect for delicate tasks.

14.    What is a standard microwave size? 
A standard microwave size typically ranges from 0.7 cu. ft. – 1.6 cu. ft. in capacity. Most countertop models fall within this range, with 1.1 - 1.4 cubic feet being the most common. These sizes are suitable for everyday cooking tasks, such as reheating leftovers and cooking simple meals. However, dimensions can vary, so it is important to consider the specific model when planning for space.

15.    Are stainless steel interior microwaves better? 
Yes, they are durable, resistant to corrosion, staining and easier to clear than plastic interiors, which ultimately keeps the microwaves looking brand new. The SHARP SMC1585KS 1.5 c.u. ft. 900W convection microwave comes with a stainless steel interior.

16.    What capacity is a family size microwave?
A family-size microwave typically ranges from about 1.1 cu. ft. – 2.2 cu. ft. in capacity. This size is suitable for cooking larger meals, fitting larger dishes, and accommodating multiple servings, making it ideal for families. The SHARP family sized microwaves include the SMC1162KSC, SMC1464KSC, SMC1585KS, SMC1664KSC and SMC2264KSC.

17.    What does an Inverter do on a microwave?
An inverter in a microwave allows for more consistent and precise cooking by providing a steady stream of power instead of the typical on-and-off cycling of traditional microwaves. This technology maintains a constant temperature, which helps evenly cook or defrost food without hot spots or overcooking. It is particularly useful for delicate tasks like defrosting meats or reheating leftovers, ensuring they are heated evenly throughout.

18.    What is the child lock on a microwave?
The door is “locked’ and cannot be opened. This lock prevents burns, access and avoids accidentally operation by a child or anyone unfamiliar with the unit.

19.    Can I disable the child lock on a microwave?
You can disable the child lock on SHARP countertop microwaves. For instructions on how to disable, refer to your unit’s owner’s manual.

20.    Does a Countertop Microwave need a special outlet?
No, small countertops have lower wattage than built-in units and can be plugged into a standard outlet on a shared circuit. 

21.    Can a Countertop Microwave replace a built-in microwave?
Short answer, yes! If you are looking to add more counter space without requiring a complete kitchen remodel, using a countertop microwave as a built-in is great option. The quickest and safest option is to mount your countertop microwave on a shelf or existing built-in cabinet. Adding an additional trim kit will give you the finishing touch. When making the switch, please take into consideration, size, ventilation, electrical outlet, aesthetic considerations, and safety. 

22.    What happens if you put a Countertop Microwave in an enclosed cabinet?
This type of installation can become a fire hazard for your kitchen. A countertop microwave is designed exclusively for a kitchen countertop, as the vents are built into the back of the microwave own. If you install into an enclosed cabinet, these vents will be blocked and unable to release steam from the microwave oven. The only way to use a microwave in an enclosed cabinet is with a compatible trim kit. 

23.    What is a trim kit?
A microwave trim kit is designed to provide a built-in look while also providing the air flow necessary for proper operation of the unit. This frame attaches and encases the microwave cabinet cut-out. Trim kits are specific to the model and the size of your cabinet, so make sure the trim kit you purchase fits your model and cabinet dimensions. 

24.    What accessories are available for Microwaves?
Great question! We have trim kits available, a 27” RK94S27F and 30” RK94S30F which are compatible for our SMC1585KS Carousel® Countertop Convection + Microwave Oven. They are sold separately and do not come with the microwaves. The key difference between the two is the trim frame and we recommended to only use the trim kit designed for the specific microwave model so that the trim kit fits the microwave and provides the proper air flow that is required.

25.    How do you clean a microwave?
Cleaning your microwave will help the longevity of the appliance. We recommended to fill a microwave-safe bowl with 1 cup of water and combine with 1 tablespoon of vinegar, 1 tablespoon of lemon juice or 1-2 tablespoons of baking soda. Microwave for 2 to 5 minutes and allow the dish to cool before removing. During this time, this will allow the steam to loosen the grime. Wipe down the interior with a damp cloth or sponge.
