Thread: Samsung Dryer overheating then not heat

    Question Samsung Dryer overheating then not heat

    Model Number: DV48H74000E
    Brand: Samsung
    Age: 1-5 years

    After reading a lot of these threads, I have come to realize I have made a huge mistake by buying a Samsung washer and dryer. To keep this short it started overheating and sometimes would run with 1 minute left on the timer until we turned it off. My power bill for sure noticed. I had called a repair man but he never came and cancelled multiple times, so I tried to do it myself. I replaced the element, which did have a crack in it. Alas, it wasn't overheating....but now there was no heat at all. The next weekend I replaced the two sensors. Success!!! HEAT!...then in a flash it was gone. I swear I have checked everything on this forum that has been recommended. I am not an electrician but I know the breakers are good and there is power to the board and then to the unit when I turn it on, but again I am not an electrician and may have missed something. Could there be any other reason for this, other than Samsung should quit the appliance business?

    Below is a link to a service manual.
    You will have to join the site to be able to download it.

    Do you have a multi-meter and do you know how to use it?
    The first thing to check is the power to/at the unit.
    Did you check/clean the vent system when you replaced the heater?
    Did you check/clean the interior of the unit including the blower wheel?

    Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
    Check the voltage at the wall receptacle
    L1 to L2 should be 240 volts
    L1 to Neutral and L2 to Neutral, both should be 120 volts.
    If OK
    Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
    If OK
    Check the power at the terminal strip.
    Do this with the heater off and on.
    Be careful as 240 volts is lethal !!!

    PS: I think you have one too many zeros in your model number.
