COS-F965NF FAQ

Q: Why does it smell like paint or chemicals when I use my oven for the first time?

A: This is the result of residue from the manufacturing process burning off. Open all of the windows and doors in the room for proper ventilation and allow the oven to run with nothing inside for at least 45 minutes before the first use.

Q: How can I tell when my oven has been preheated to the selected temperature?

A: Your Cosmo dual fuel range is equipped with an indicator light above both the oven function and oven temperature knobs. The light will illuminate while the oven is preheating and will turn off once the oven has reached temperature. It will switch on and off throughout the cooking cycle as the internal heating elements cycle on and off to maintain the set temperature. 

Q: How do I set the clock on my range?

A: The clock can only be set when the unit has been powered on for the first time, or power has been reset. The clock will blink and show “12:00” and a bar will be displayed above the clock icon. Press the left and right buttons below the display until the correct time is displayed. After 5 seconds, the clock will start automatically, or you can press the center button to confirm. 

Q: How do I set the timer on my range?

A: The digital countdown timer can be set up to 12 hours and 59 minutes. To set the timer, press the center function button repeatedly until the bar above the first icon (bell) is displayed. Press the left and right buttons below the display until the desired time is displayed. After several seconds of no interaction, the timer will start.

Q: How do I set a cook timer on my range?

A: The digital countdown timer can be set up to 12 hours and 59 minutes. To set the timer, press the center function button repeatedly until the bar above the third icon (crossed-out dish) is displayed. Press the left and right buttons below the display until the desired cook time is displayed. Select the oven function and temperature. The oven will automatically turn off when the timer ends.

Q: Does my range come with a manufacturer’s warranty?

A: This range includes a 1-year manufacturer’s warranty with your new purchase from an authorized retailer. To view a list of authorized retailers, please visit www.cosmoappliances.com/locations. 

Q: Where can I find the warranty terms for this product?

A: The warranty terms are available online at www.cosmoappliances.com/warranty. Your unit is covered for both parts and labor for 1 year from the date of purchase. 

Q: All of my burners are clicking or sparking when I turn any of them on.

A: The burners on this unit will spark when you attempt to ignite any of them. This is normal operation and is an intentional side effect of the cooktop’s design.

Q: Why is hot air blowing out from the top of my oven door?

A: Your oven is equipped with a cooling fan to better regulate the internal temperature for more precise cooking. There are two vent locations: on top of the oven door, and behind the cooktop. This is intended by design and is normal operation.

Q: Why does my oven’s fan continue to run with convection mode off or after the oven has been turned off?

A: This is normal operation. The cooling fan will remain on during the baking cycle, regardless of the convection function, as well as after the oven has been shut off until it has sufficiently cooled.

Q: Why is my unit producing black soot when in use?

A: The most common cause of black soot being produced when using either the oven or the cooktop is an improper propane mixture or conversion. Check the propane gas source first, then review the LP conversion instructions.
