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 gas oven does not include an alert or indicator that the oven has reached the selected temperature. We recommend using a standard oven thermometer inside the oven to indicate when the oven has reached its set temperature. The oven will take 10-20 minutes to preheat depending on the set temperature.

Q: My oven indicator light never turns off, even after the oven has reached the set temperature.

A: The oven indicator light on your Cosmo range stays on as long as the oven is on. It will turn off once the oven knob is turned to the OFF position.

Q: Why do the lights above the knobs stay on even when I am not using the unit?

A: The indicator lights above the knobs are manually switched on and off using the button switch on the left side of the control panel, labeled “Panel Light.” 

Q: How do I remove the oven racks for cleaning?

A: If your racks are on sliders, the sliders are resting on the guides and must be removed along with the oven racks. If your oven racks do not have a slider/caster, they can simply be slid all the way out and removed.

Q: How do I remove my oven door? 

A: You can remove your oven door by following the instructions found on pages 34-35 of the user manual, or by viewing the image here

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

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

A: The warranty terms are available here. 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 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.

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.
