Thread: Replaced every part on Dryer and it still does not heat

    Replaced every part on Dryer and it still does not heat

    Model Number: DV331AEW/XAA
    Brand: Samsung
    Age: 1-5 years

    When our dryer stopped heating we went online and did some trouble shooting. We concluded that the thermastor needed to be replaced. When that didn't fix the problem we called a technician. After he tested everything and checked breakers etc., he determined we needed a new computer. When he told us how much it would cost to replace it, we decided to buy the part and do it ourselves. That didn't solve the problem either. I called him and spoke with him about our issue and he said to replace the motor. I went and got the new motor and my husband installed it. Still no heat. Today we bought the heating element assembly and installed it and the dryer still won't heat. We have checked the breakers again and there is nothing left to replace at this point, other than the drum and belt, which I don't think have anything to do with heat. I have never used dryer sheets, I clean the vent after every single load and have vacuumed every inch of every part of this dryer. We are completely stumped and beyond frustrated. Hanging our clothes to dry all over the house has really become a chore. Please advise if anyone can think of anything we may not have tried. We could have bought a new machine with what we have spent. Help!!

    What do you mean by check the breakers?

    Did you check the voltage at the wall plug and also at the terminal strip in the unit?

    If yes what were the volatges.
    L1 to Neutral
    L2 to Neutral and
    L1 to L2.

    The technician said he checked the voltage, and that everything was fine, but we are starting to think that maybe he was shady. So, my husband is going to pick up a multi meter to check the voltage for himself. I have a feeling, after replacing every single part on this dryer, that it is going to be voltage related, grrrr. Please stand by and I will report our findings! Thank you a bunch for responding!!

    Well, after using the multi meter, the voltages all check out fine. This is beyond perplexing.

    The parts you replaced are all of the heating components listed in the wiring diagram on this model dryer. If the dryer is not heating after replacing these parts there must be a break in one of the wires somewhere. Have you checked the wires where the power cord attaches to the terminal block on the back of the dryer for any burned or broken wires?

    Yes.
    I tested both legs and each leg reads 110v to neutral.
    The leads are tight and look brand new.
    Everything else works, just no heat.

    Stumped.

    You said "I tested both legs and each leg reads 110v to neutral." but did you check for the 240 volts (L1 to L2)?

    Just checking for 120 is no good as one side of the line can feed through some parts and show up on the other side of the line.

    Just checked L1 to L2 and meter shows 220v. What is my next step?

    Do you have the tech sheet / wiring diagram?
    You will need this to help track down where the heater circuit is open.

    I will try and locate it, and I will let you know what I find. Thank you for sticking with me on this!!

    Since you do not have it try the following.
    The pdf is too big to attach directly on this site so I have had to use a third party site.
    Hopefully it will work for you.

    https://www.datafilehost.com/d/5af871a0

    Uncheck "Download with Secured Download manager"
    Then use the light grey Download button.
    This should ensure that you do not download any software that you do not want on your computer

    I LOVE you

    I do not know you, but I love you!! My husband just used the information you sent and starting running thru the tests on the dryer. He had no idea what he was doing, other than going thru a sequence that you sent. He would turn the dryer on periodically to see if it was working and it is now working!!!!!! This has been a nightmare for many weeks. Can you shed some light on what just happened?? I am just wondering if after he replaced the first part, if he would have tested it, it would have started working. My guess is that there was some sort of "reset" that just occurred. Whatever it is, you rock, you are the best and thank you from the bottom of my heart for taking so much time to see this situation thru to the end!!!

    Problem: Replacement thermal cut-off part# DC47-00016A keeps blowing off.

    Solution:

    The replacement DC47-00016A is actually a PC-17/PC-17S B-2 K85 thermal cut-off, which is spec'd to cut off at 85*F.

    The original part I removed was a CS-7 B-2 K160 thermal cut off, which is spec'd to cut off at 160*F.

    Use the part Dryer Thermal Fuse DC47-00015A instead of DC47-00016A. Also it is recommended to replace thermistor part #DC32-00007A. This should solve it.

    I have changed almost every part. I am going to replace DC47-00016A with DC47-00015A and replace thermistor part #DC32-00007A on Feb 21st. I will keep you posted with the results.

    Success! Make sure the thermal cut-off has cut off at 160*F and not 85*F, sold by most seller.

    All I can think of is that there was a loose/bad connection in the heating circuit.
