Overview
Sharp's R1874TY is a 1.1 cu ft over-the-range convection microwave rated at 850 watts, built as a near drop-in replacement for the carousel convection microwaves common in older motorhomes and RVs.
Long-time RV owners treat this as the successor to a Sharp carousel model many of them ran for decades, and several describe swapping it in without redrilling. It genuinely bakes and roasts via 12 convection programs rather than just reheating. One reviewer with a monitored solar system measured actual power draw far above the 850 watt cooking rating, worth knowing for anyone sizing an off-grid electrical setup.
- 13 inch turntable with on/off control
- Built-in exhaust fan and hood light
- Outer dimensions 29-15/16 x 16-11/32 x 15-9/32 in
- Stainless steel 1.1 cu ft interior
Who it's for
Best for RV and motorhome owners replacing an aging Sharp OTR convection unit in the same footprint. Not ideal for off-grid solar setups that need to budget tightly for peak draw.
Pros and cons
- Turntable switches off for square convection bakeware
- 12 convection programs alongside standard microwave modes
- Popular direct fit replacement for older Sharp RV ovens
- Measured power draw ran well above rated wattage
- Sized specifically for RV and motorhome cutouts
Performance notes
12 convection programs handle browning, baking, broiling, crisping and roasting on top of standard microwave cooking, and the turntable can be switched off for square or rectangular convection bakeware. A built-in exhaust fan with hood light vents the cooktop below, and the 2-color, 7-digit display keeps settings visible.
