Why some burners will not light on my Cosmo COS-EPGR486G Ranges?

If some burners on your Cosmo Ranges won't light, several issues could be the cause. First, ensure burner parts and igniters are clean, dry, and correctly assembled. Clogged burner bezel ports can also prevent ignition, so clean them with a straightened paper clip, needle, or wire. Check that burner ports or burner caps are positioned properly, re-installing them carefully if needed. Confirm the cooktop is using the correct type of gas and that the regulator is properly installed and set. Ensure the gas shut-off valve is in the βONβ position. If the power supply polarity is reversed, have it corrected. Also, make sure air intake holes around knobs are unobstructed. If the gas supply pressure is low, contact your gas company.
