    Default Samsung DV220AEW not heating - need some help

    Model Number: DV220AEW
    Brand: Samsung
    Age: 6-10 years

    Hello all,

    My dryer is not hearing, but everything else seems to be working.

    I found the thermostat was dead, so I replaced it with a new one, which worked for exactly one load and then was blown again. I thought perhaps I had a bad thermostat, so put in a new one and same thing. One load and done. Took a look and it looks like the wire that runs between the thermistor and thermostat is cooked and frayed at the end point (clip) on the thermostat.

    A couple of questions.

    1) what wire do I replace this with? I can't seem to find a replacement wire in the parts listing. Could I simply go to a hardware store and replace the wire with a 6 inch piece of generic wire, and if so, what wire specs should I get?

    2) what could cause this? I also had the plastic idler pulley fail, because the pulley seized on the idler arm, causing the belt to melt through the pulley. Could that have caused the initial overload/wire burning issue?

    The wire itself is exposed and brittle, and the insulation is gone making me wonder how close I came to a house fire.

    I am planning on replacing the thermostat and the thermistor as well as the wire. Should I also replace the heating element? The thermistor tests good, but I thought I should replace it if it could be causing the problem.

    Thanks for any help!

    You can certainly replace the element and thermistor if you want to but it's not necessary. I'm a firm believer of, "It it ain't broke, don't fix it". Bad wires and wire connections will cause the machine to draw more current. More current is more amps. More amps = heat. Take a piece of the wire with you to one of the home centers and match it up. Replace any burned wires on the machine. Last and more important is, you need to clean out the vent hose and outside vent. Check the air flow at the outside vent when you're done.

    Thanks.

    I have already replaced the wire with a new section. Could the thermostat be the reason the wire was fried? I'm wondering if the reason the wire was toast was because something else caused it. I guess it could be the wire was always bad and it just hit its breaking point. I don't want to replace yet another thermal fuse assembly if there is something upstream that caused the wiring problem.

    Rick,

    Does it matter what order the connectors are put on the thermostat and the thermal breaker? On my dryer the heating element is the first item connected, and then the thermostat, followed by the breaker. There are two wires connecting the clips on each of these items, but there doesn't seem to be any +/- issues to look for. Also, there doesn't seem to be any requirement for which way to place them (not sure if there is a right side up/upside down issue for either the thermostat or breaker). Any help would be appreciated!

    Thanks again

    The wire became "toast" over time. A thermal fuse won't cause it to go bad.

    I'm not following you, sorry. What breaker are you referring to and what thermostat are you referring to. The high limit t-stat?
