Cooking Modes:
The oven offers 7 distinct cook and baking modes to accommodate a wide range of culinary needs:
- Bake: For general baking of cakes, cookies, and casseroles.
- Broil: For searing, toasting, or browning food quickly under direct heat.
- Convection Bake: Utilizes a fan to circulate hot air, ensuring even baking and browning, ideal for multiple racks of cookies or pastries.
- Convection Broil: Combines broiling with convection for faster, more even browning.
- Convection Roast: Ideal for roasting meats and poultry, providing a crispy exterior and juicy interior.
- Warm: Keeps cooked food at serving temperature without further cooking.
- Proof: Provides a low, consistent temperature for rising dough.
Additional special features include an Air Frying Mode (requires compatible accessories, sold separately), Interior Light for visibility, Self-Cleaning function, and Shabbat Mode for religious observance.
Using the Convection Feature:
The rapid convection cooking process utilizes fan-assisted heat distribution to cook food more evenly on the top, bottom, and throughout. This improves food taste, quality, and overall cooking speed. When using convection modes, you may need to adjust cooking times or temperatures slightly compared to conventional recipes.

Maintenance and Care
Regular cleaning and proper care will ensure the longevity and optimal performance of your KoolMore oven.
Self-Cleaning Cycle:
The oven is equipped with a self-cleaning feature. To activate, ensure the oven is empty and the door is securely latched. Follow the instructions on the control panel to start the cycle. During self-cleaning, the oven reaches very high temperatures to burn off food residue. A slight odor is normal. After the cycle, allow the oven to cool completely, then wipe away any ash with a damp cloth.
Exterior Cleaning:
- For the stainless steel exterior, use a soft cloth and a mild detergent or a specialized stainless steel cleaner. Always wipe in the direction of the grain to prevent streaking.
- Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- Clean the control panel with a soft, damp cloth. Do not spray cleaners directly onto the panel.
Interior Cleaning (Manual):
For light spills or areas not covered by the self-clean cycle, use warm, soapy water and a soft cloth. For stubborn stains, a non-abrasive oven cleaner can be used, following the product's instructions carefully.
