COS-244AGC Electrical Installation Troubleshooting – 120V

Gas range or cooktop No power or low power. Check that the unit is plugged in and the breaker is switched to ON. Check that the voltage is correct for your unit according to the installation manual – 110/120V, 60Hz, and 15 to 20 Amps. Turn the breaker to the OFF position and wait 5 minutes. Turn the breaker back to the ON position and attempt to use the unit again. We advise that electrical installation be performed by a qualified, licensed electrician. If installation was not performed by a licensed professional, contact one as soon as possible to verify that the power is adequate for your unit and has been safely connected.

Calibrate COS-244AGC Cooktop Burners

Read all instructions carefully before beginning. Light two other burners and turn the control knob to medium. This will ensure the burner’s flame does not extinguish when other burners are turned on. Light the burner needing calibration and turn the control knob to the lowest setting. Remove the control knob. Insert a small, flat-head screwdriver into the adjustment screw or control knob valve stem, and slowly turn the screw until the flame appearance is correct. Open the valve more (counter-clockwise) if the flames are too small or fluttered, or the flame extinguishes entirely. Close the valve more (clockwise) if the flames are too large. Replace the control knob. Test the flame by turning the control from “LO” to “HI,” checking the flame at each setting. Repeat the above steps for each burner. 

Adjust COS-244AGC Oven Burners for LP Gas

Locate the air inlet cap, found on the far right side of the oven burner as shown in Figure 1. The oven burner can be found by removing the rectangular burner cover on the floor of the oven. The mounting screw on the far left side of the oven burner can be removed to allow easier access to the air inlet cap. Loosen but do not remove the screw on the oven burner’s air inlet cap. The location of the screw is indicated by the red arrow seen in Figure 1. Rotate the air inlet to align the cap with the engraved marking matching your gas type (NG / LPG).  Tighten screw on the burner’s air inlet cap.

Adjust COS-244AGC Regulator for LP Gas

Figure 1-A Figure 1-B Figure 1-C Read all instructions carefully before beginning. NOTE: Your regulator may not match the images exactly, but the procedure will remain the same. Disconnect all electrical power at the main circuit breaker or fuse box. Shut off the gas supply to the unit by closing the manual shut-off valve. Unscrew the cap on the regulator using a wrench as shown in Figure 1-A. Unscrew and remove the retainer pin that is currently positioned for natural gas as shown in Figure 1-B. The position shown in Figure 1-B is the natural setting. If the retainer pin has not yet been flipped, remove the retainer pin and re-insert into the cap as shown in Figure 1-C. Replace the regulator cap and tighten using a wrench. Your regulator is now set up for LP gas.

COS-965AGFC 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: Why does my oven flame stay on during the entire cooking cycle? A: The oven on your Cosmo range uses a manual spark ignition with no auto reignition. The flame is designed to stay lit until the oven has been turned off. As your oven goes through the bake cycle, the size of the oven flame will increase and decrease to keep an average temperature within 20-30 degrees of the set temperature.  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: How do I set the clock on my range? A: Press the center button below the display until the bar above the Clock icon is illuminated. Use the right (+) and left(-) buttons below the display until the correct time is displayed. The clock cannot be set while a cooking end time is active. 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: 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 here. Your unit is covered for both parts and labor for 1 year from the date of purchase.  Q: Why can’t I turn my oven knob? A: This oven uses an electronically controlled oven ignition system and will not turn when the knob has been fully pushed in or fully released. To light the oven:  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 temperature between the oven cavity and the external walls of the unit. This is an advanced safety feature to help prevent burns when touching any of the panels, knobs, or the door handle. There are two vent locations: the 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.
