Thread: Control Board Carbon Monoxide?

  1. #1

    Control Board Carbon Monoxide?

    Model Number:
    Brand: Sears Kenmore
    Age: 6-10 years


    New here. My Kenmore gas dryer has been causing an unburnt/improperly burnt fuel smell sporadically recently along with emitting carbon monoxide. We had the duct connecting the exhaust to the venting replaced but still have this problem. The CO has spiked up to 500 at times. Once we stop the dryer and air the house out (and leave for a while), it goes back down to 0. I was told that the smell and CO both could be signs of a faulty control board. Before I proceed with having a repair person come out, I wanted to see if, based on everyone's experience, that issue could cause the "symptoms" I am describing.

    Thanks ahead of time for any help!

    1st potential prob:
    Might Be The Thermal Fuse
    Your fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity which means, the electrical path is broken and your fuse has blown. Always check the dryer venting when replacing a blown thermal fuse.
    Prob 2:
    The Gas Valve Solenoid
    I think pretty much all gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve ports to allow gas to flow into the burner assembly. If a gas valve solenoid fails, the dryer won’t heat. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, then just go ahead and replace the set.
    Potential Prob #3:
    The Igniter
    The igniter uses heat to ignite the gas in the burner assembly. If the igniter is not working, the gas will not ignite, preventing the dryer from heating. To determine if your igniter has burned out, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.

    Just my 2 cents...
    Hope that helps.
