  • Samsung Dehumidifier - beeps

    Hi,
    I have a Samsung model DED50LL dehumidifier. When on it beeps twice every two seconds. While doing this, the fan is cyciling on with the beeps. The compressor isn't running though. When I turn off the power, it beeps once every two seconds. It only stops beeping when I unplug it. I unpluged overnight and turned back on the next morning and it was fine. Then was doing it again a day later. I thought it might be the coils freezing up, but I thought it had to be under 65 degrees or so for that to happen. I have a fiished basement and it may be 70 degrees down there but definetly no colder than that. I can't actually see the coils as they are covered. Maybe a next step would be to remove the cover to see if they are freezing?
    Nothing in the owners manual or any help from Samsung customer service.
    Anyone have any thoughts?
    Thank You.

    I would have to believe that the beeping is an alarm of some sort. there is a sensor that indicates a full condensate bucket. I don't think that any dehumidifier unless it is a very large unit would indicate to the user that a freon level is low. you said the fan cycles along with the cyclic beeping, so its turning on and off along with the on-off beeping. that indicates a problem with the circuit that turns on the fan. the enthalpy control, which determines the humidity you desire may be faulty. Its nothing but a membrane connected to a switch. check it out.

      Thanks for the quick reply.
      If something was faulty electronicly, wouldn't it do it all the time? as I said in my original post, I unpluged overnight and tuned on again and it worked fine for a day, until it started acting up again.

        then it would seem to me that a sensor was faulty somewhere in the system. like a condensate drain pan sensor. if the two probes were in water and then left standing, some of the water would evapotate away from the probes, then as it filled up the probes would be covered with water starting the beeping again.

          Not necessarily. Electronic controls can fail in such a way that they're intermittent but I agree with HayZee that it is more likely trying to tell you something. What that something is I don't know.

          Any filters on your model which are supposed to be periodically cleaned/replaced?

          Any other blockages in the units air flow?

          Any problems with the moistural bucket or water level?

          I thought it might be the coils freezing up, but I thought it had to be under 65 degrees or so for that to happen.
          There are other conditions and problems which could cause it as well but running one below that temperature will almost always cause it on a standard dehumidifier model.

            Well I took off the cover and indeed the coils are freezinf up. But the conditions in the basement have not changed. It just started happening. Anyone know what the temp. is that this would happen at. I really don't believe it's below 70 degrees down there. I guess I could put a thermoter down there to verify.
            Any more thoughts?

              Uniformly across the evaporator coil's *whole surface* or just part of it?

              It is dependent on both temperature and humidity. There is no one set temperature a dehumidifier is guarantied to frost up at.

              I really don't believe it's below 70 degrees down there. I guess I could put a thermoter down there to verify.
              It's always a good idea to work with actual facts.

                restricted air flow over the coils will cause a coil freeze up. condensate on the coils freeze and as more condensate appears it re-freezes on the coils eventually plugging up or freezing over all the coils - restricted air flow will do this.

                  They all freeze up.
                  Conditions in the basement have not changed while this has happened. Temperature is 73 degrees. This leads me to believe something is wrong with the unit, but I have no idea what.
                  So I bought a new one yesterday, plugged it in all is good.
                  It's a shame I had to scrap a three year old unit though, must have been a lemon.
                  Thanks anyway for all the replies.
