The TOSHIBA OptiChef ML2-STC13SAIT(SS) is a countertop microwave oven that combines microwave, air fryer, convection, broil, and defrost functions in a single unit. It features a 2.4-inch color screen, Origin Inverter Technology, a smart humidity sensor, and smart connectivity via the TSmartLife app and Alexa voice control. The oven has a 1.3 cubic foot capacity and delivers 1100W of output power.
This appliance is designed for residential countertop installation. It includes a microwave rack and a 13.6-inch turntable. The interior is finished with ceramic enamel, and the exterior is stainless steel and glass.

The oven is equipped with a 2.4-inch colorful TFT ChefView screen. The interface is touch-responsive and provides visual feedback for cooking progress, menu selection, and settings.

The Origin Inverter provides precise, variable power control instead of simple on/off cycling. This results in:

A top fan and heating element replicate the effect of an air fryer oven, allowing for healthier cooking with less oil while achieving crispy results.

The built-in humidity sensor automatically detects moisture levels during cooking and adjusts time and power accordingly. This helps prevent overcooking and retains natural moisture in food.
The Chef Defrost function uses the inverter technology to defrost food up to 40% faster than traditional methods while preserving the original texture and flavor.

WARNING: To reduce the risk of burns, electric shock, fire, injury to persons or exposure to excessive microwave energy. When using electrical appliances, basic safety precautions should be followed, including the following.







This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
WARNING - Improper use of the grounding can result in a risk of electric shock. Consult a qualified electrician or serviceman if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded. If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3-blade grounded plug, and 3-slot receptacle that will accept the plug on the appliance. The marked rating of the extension cord shall be equal to or greater than the electrical rating of the appliance.
DANGER Electric Shock Hazard:
Touching some of the internal components can cause serious personal injury or death. Do not disassemble this appliance.
WARNING Electric Shock Hazard:
Improper use of the grounding can result in electric shock. Do not plug into an outlet until appliance is properly installed and grounded.
