Convection Countertop Oven

Oster Convection Countertop Oven TSSTTVF816

The Oster Convection Countertop Oven models TSSTTVF816 and TSSTTVF817 are household countertop cooking appliances designed for baking, Turbo Convection Bake, variable broiling, toasting, and warming or defrosting food using adjustable temperature and timer controls.

The oven features a removable wire rack that also serves as a broiling rack, a baking pan, a crumb tray, and a tempered glass door. Its two rack positions accommodate different food sizes and cooking requirements, while the easy-clean interior walls simplify routine maintenance.

The Turbo Convection Bake function uses a built-in fan to circulate hot air throughout the cooking chamber. This helps maintain a consistent oven temperature and can reduce cooking time compared with conventional baking.

Three rotary control knobs provide the main operating functions: a temperature selector, a function selector, and a timer selector. The timer can be set for up to 60 minutes and automatically switches the oven off when the selected time expires. A separate Stay On setting allows cooking to continue until the timer is manually turned off.

The countertop oven operates from a 120-volt AC electrical outlet and is intended for household use only. Proper ventilation, appropriate rack placement, oven mitts, and regular crumb tray cleaning are important for safe operation.
