    Dryer runs but does not heat
    My Kenmore dryer, model number 41783142300, runs but does not heat. No clogged vents, lines, etc. Any ideas on the problem? Where do I start. The electric breakers all look good.

    We have an older dryer that did the same thing. It ran just fine but didn't dry the clothes. We replaced the heating element and then it worked just fine.

    1. Gas valve coils
    Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

    Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

    2. Thermal fuse
    Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

    Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

    3. Igniter
    Igniter may burn out or break. Replace the igniter if found defective.

    Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

    4. Flame sensor (or radiant heat sensor)
    Replace the sensor (located near the igniter) if found defective.
