Sharp R21LCFS Medium Duty Commercial Microwave Oven 1000W 1.0 Cu Ft Electronic Dial Timer Stainless Steel
Sharp R21LCFS — 1000W Commercial Microwave with Electronic Dial Timer
The Sharp R21LCFS (R-21LCFS) is the dial-control model in Sharp's medium duty commercial microwave line, built for kitchens and service counters that heat, defrost, and cook small items rather than run high volume. It delivers 1000 watts of output power into a 1.0 cu. ft. stainless steel cavity, and a 6-minute electronic light-up dial timer replaces touchpads with one twist. Because the dial is electronic, opening the door mid-cycle cancels the remaining time instead of letting it run on an empty oven. The stainless steel cabinet, interior, and door, together with Sharp's rugged latch grab handle, are made to hold up to the constant open-and-close of a break room or convenience store, and the unit plugs into a standard 120V NEMA 5-15 receptacle.
Key Features of the R21LCFS
The R21LCFS keeps operation to a single dial and a single power level, which is exactly what a self-serve or high-turnover setting needs: nothing to program, nothing for staff to change by accident.
6-Minute Electronic Dial Timer
The light-up dial is clearly marked in 10, 15, and 30-second increments up to 6 minutes, so short reheats and longer cooks are both set by eye in a second.
Auto Cancel on Door Open
Open the door during cooking and the remaining time is cancelled. Mechanical dials keep counting after the food is out, which wastes energy and shortens magnetron life.
Built-In Heating Time Guide
A heating time guide on the front recommends times for a variety of popular foods, giving staff and customers an on-the-spot reference without a printed chart.
Stainless Steel Inside and Out
The cabinet, the 13-7/8" x 8-1/8" x 14-5/8" interior, and the door are all stainless steel, so spills wipe off and the finish stands up to daily commercial cleaning.
Rugged Latch Grab Handle
Sharp's specially designed latch handle is built to reduce door failure, one of the most frequent problems on lesser-quality microwaves in shared, high-traffic use.
Single-Stage, 100% Power
One cooking stage at full 1000W power keeps operation foolproof for smaller kitchens that do not need volume cooking or multi-stage programs.
Electrical note: The R21LCFS requires 120V, 60 Hz power and a NEMA 5-15R receptacle; it draws 14 amps (1.55 kW input), so plan the circuit with other countertop equipment in mind. Need programmable memories or variable power? The R21LVF (10 memories) and R21LTF (20 memories, 11 power levels) share the same 20-1/2" cabinet.
Ideal Applications
Sharp positions its medium duty ovens for settings that heat, defrost, and cook small items throughout the day without the cost of a high-powered unit.
