Q: Do you offer an extended warranty?

A: Cosmo does not currently offer an extended warranty for any of our products. We recommend reaching out to the retailer where you purchased your item, as many extended warranties are provided and fulfilled through the retailer. 

Q: Where can I find the model and serial number of my unit?

A: The model and serial numbers can be found in one of three places: on the inside of the oven door jamb, on the inside of the oven door itself, or on the rear of the unit on the manufacturing sticker. We recommend writing this information down so you have it for easy reference.

Q: Can I convert my range or cooktop to liquid propane gas (LP gas)? 

A: All of our gas cooktops and ovens can be converted to LP gas with the use of an appropriate LP conversion kit. All conversion kits can be found online at www.cosmoappliances.com/product-category/parts-and-accessories

Q: Why is the food cooking unevenly in my Cosmo oven?

A: This can be due to many factors such as the type and quantity of food being cooked, whether or not convection mode is being used, where the food is placed in the oven, whether or not the food is being rotated during cooking, etc. We recommend trying to experiment with different foods and methods of cooking as you become accustomed to your new Cosmo oven.
