When the door is opened during cooking, the remaining time is cancelled; saving energy and increasing the magnetron's life. Stainless steel exterior wrap and interior for easy cleaning and a commercial look. A handy "on-the-spot" reference for timesaving convenience is located above the timer with recommended times for heating a variety of popular foods. Review: Perfect, if you just need to microwave stuff - After our previous two microwaves had their plates break or chip, and one of them started randomly burning food, I decided to see if there was anything out there that would be more reliable. We ultimately settled on this one, because even though it's more expensive than even the fancy consumer microwaves it has three important advantages that none (or very few) of them have: 1) It is built to last. Everything on this microwave is purposefully simple and apparently designed to minimize the possibility of breakage. Instead of a plate that will get dragged out with the food and shatter on the floor, it has a glass floor that's fixed onto the body of the microwave. Instead of a push-button control panel whose buttons will inevitably crack or get desensitized, you have an "infinite rotation" wheel that is solidly attached; and because it's not calibrated physically it won't get out of alignment. Instead of a clock that you will continually have to reset, it has ... no clock. The interior is metal all around and all surfaces are easy to clean and seem resistant to scratching. 2) You can intuitively and freely modify cook time while the food is heating. Just spin the wheel, and it does exactly what you'd expect. I can't understand why almost no digital microwave will let you do this, but now that it's easy I do it all the time. 3) Instead of a carousel it has a different kind of heating mechanism that ensures even heating without actually moving the food. This means you can heat larger or odd-shaped dishes without hotspots and without knocking your plate out of alignment. I was surprised at how well this works in practice -- food consistently requires less stirring and has less temperature variation after heating than with any other microwave I've ever owned or used. Naturally you should still be cautious about checking your food before shoveling it in your mouth or feeding it to a small child, but it's nice not to have so many frozen-in-the-middle burritos or ice-cube-like tofu chunks in your leftover chinese food. If you'd like to use variable temperatures or auto-cook, or presets for popcorn, or have another clock or timer, or have something that's also a convection oven, or do anything other than heating food or food-like stuff in an intuitive and foolproof way, look elsewhere. If you are willing to pay more for a microwave that does one thing and does it better than you'd expect, this is the one. Review: Perfect for My Needs and Personality - I love how well-built this machine is. I like the simple clarity of the timer dial. I love the easy-on-the-ears ring at the end of the cycle. How deep the cavity is. How strong the microwave is. How accurate. I picked this one because it was highly rated, reputed to be durable, simple, functional. That suits me to a T. I'm happy that it's gray on the sides and top and stainless only on the front. I love seeing the remaining time light up -- none of that hard-to-view digital junk. There are slight tactile indentations at the time intervals on what I originally thought was an entirely flat timer on the faceplate. In addition, there are slight "bumps" at the time intervals when turning the knob (which is smooth). These tactile indicators are very slight but still discernible to my uneducated fingertips. If I lose my eyesight, I can use those to track the time in the microwave. That the food does not need to rotate is terrific. This machine always gets my coffee, my leftovers, delicate pastries, everything finished evenly and precisely. This Sharp microwave looks really -- well, sharp! For what it is worth, I am an aging woman who always preferred function and durability over trends and designer stuff. This looks better in my book. I've had enough pretty microwaves that took up enormous amounts of counter space and died in less than a year. Thank goodness, this type microwave from Sharp is still available and to individuals, not just to businesses. Please note that the ring at the end is not obnoxious. It cannot be turned off though, so if you're looking for no ring or buzzer at all, look to the next-level-up models. My Sharp says inside the door that it was made in Thailand. The squeeze handle is easy enough for even me with my loss of hand strength to "grip open" and boy this door is so much more quiet than the ones on microwaves without handles! I don't wake the family when I warm something in the middle of the night anymore. And one more thing, a family member with cognitive problems is finally able to heat his cup of chocolate by himself -- the functions are that clear. ## Features - SIMPLE TO OPERATE: The classic dial timer can be set anywhere from 10 seconds to 6 minutes and includes bright LED indicators that permits "at-a-glace" monitoring. - SPACIOUS INTERIOR: The 1. 0 cu. ft. capacity can accommodate a 13-1/2'' platter, prepackaged foods, single servings or a half-size pan in either direction. - AUTO-CANCEL TIMER: When the door is opened during cooking, the remaining time is cancelled; saving energy and increasing the magnetron's life. - EASY TO MAINTAIN: Stainless steel exterior wrap and interior for easy cleaning and a commercial look. - HEATING TIME GUIDE: A handy "on-the-spot" reference for timesaving convenience is located above the timer with recommended times for heating a variety of popular foods. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BDF5ZNS | | Additional Features | Timer | | Best Sellers Rank | #49,327 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Commercial Microwaves | | Brand | Sharp | | Brand Name | Sharp | | Capacity | 1 Cubic Feet | | Color | Silver | | Controller Type | Electronic Dial | | Cooking Program | Defrost, Double Quantity Pad, Reheat | | Customer Reviews | 4.5 out of 5 stars 404 Reviews | | Defrost System Type | Express Defrost (Proprietary) | | Energy Consumption | 1000 Watts | | Frequency | 50 Hz | | Global Trade Identification Number | 00074000616493 | | Heating Method | Electric | | Human Interface Input | Mouse | | Included Components | Microwave | | Inner Material | Stainless Steel | | Installation Type | Countertop | | Item Dimensions D x W x H | 16.01"D x 20.5"W x 12.13"H | | Item Type Name | Microwave | | Item Weight | 16780 Grams | | Manufacturer | Sharp | | Manufacturer Part Number | R-21LCF | | Material Type | Stainless Steel | | Model Name | Sharp R-21LCFS | | Model Number | R-21LCF | | Number of Power Levels | 3 | | Product Dimensions | 16.01"D x 20.5"W x 12.13"H | | Recommended Uses For Product | Commercial | | Smart Home Compatibility | Not Smart Home Compatible | | Special Feature | Timer | | Timer Function | Timer Function Available | | Turntable Diameter | 13.5 Inches | | UPC | 074000616493 724137954523 788809602495 791943926280 | | Unit Count | 1.0 Count | | Voltage | 120 Volts | | Warranty Description | One (1) year parts and labor.

What prompted us to replace our old microwave was the presence of rust in the interior. The Sharp R-21LCFS has a sealed surface, no turntable and stainless steel interior - making it so easy to clean and impervious to the potential for rust to form. It is so very simple to use and has the power that we need. The only drawback is that it can only go to 6 minutes at a clip. But then it is pretty easy to dial up another 6 minutes. ## Frequently Bought Together - Sharp R-21LCFS Medium Duty Commercial Microwave (Dial Timer, 1000-Watts, 120-Volts) (Update of R-21LCF),Silver - Sharp R-21LCFS Medium-Duty Commercial Microwave Oven with Dial Timer, Stainless Steel, 1000-Watts, 120-Volts, One Size - Keurig K155 Office Pro Single Cup Commercial K-Cup Pod Coffee Maker, Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/36545727-r-21lcfs-medium-duty-commercial-microwave-dial-timer-1000-watts](https://www.desertcart.kr/products/36545727-r-21lcfs-medium-duty-commercial-microwave-dial-timer-1000-watts) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-30*
