  • WD816360 model wet/dry vac overheats

    For over a year my 7-3/4 years-old 16-gallon Ridgid has been slowly overheating whenever I've used it: it would run a good 10-15 minutes normally, begin to slow down -- and emit that overheating electronics smell. (I've kept it and its filters clean.) Today (with a brand-new filter) it's begun to run shorter before stopping, scarcely long enough -- with half a dozen halts -- to 'bail' a car left open-windowed during a cloudburst. Is packing & shipping it back to Ridgid my only recourse?
    Thanks in advance for all advice.

    Unless you think that your issue is definitely due to a manufacturers defect I doubt if shipping it anywhere will do you much good. The Lifetime Warranty on Ridgid vacs is only good for the lifetime of the vacuum and it sure sounds life yours is close to the end of its lifetime.

      Sounds to me like you have an air restriction somewhere. If the filter is clean as you say, then have you checked the air flow of the exhaust in comparison to the intake? Could something be clogging the vacuum hose, the air intake port, or the exhaust port? Obviously there is something that is causing the motor to overheat. Have you tried to run the vac without the filter in place; I don't mean attempt to use it to clean up anything, just turn it on and let it run without the filter and see if the motor still overheats... that would be a good indicator as to whether it's just the motor and/or perhaps that something is clogging the motor vents at the top of the housing.

      Hope this helps,

        This is a vac with the detachable head for use as a blower correct? Reviewing the manual I see it talks about ensuring the foam filter is clear. You may never have used you vac in this manner, but that foam filter is still in there, and I believe it is exposed to dust when you are using the machine as a normal vacuum, especially if your filter is not tight.

        Lift the head of the vac off as instructed in the manual and have a look. It might just be totally disintegrated from age and clogging up the intake.

        Here's a link to the manual.

          It's the model lacking a detachable blower, Bob D, but that is the same manual that came with it -- which now I see is for a Model 12701 and not my 16360, but no biggee; in every other respect it's accurate enough. In respect of what you wrote, I took a closer look at the non-detachable hood. There are vents there, in a panel that seems to have been snapped into the housing; but no clear way to remove it.
          Perhaps the motor is starving for air somehow, as CWSmith notes, in respect of which I do run it filter-less for "large" (and clean) spills as indicated in the manual.
          In respect of BadgerDave's comments, I note that the current version of my model now bears a 90-day returnable proviso. I've enjoyed almost eight years for fifty bucks, which doesn't seem a bad deal -- and I don't see the point in spending a good fraction of its initial price to send it back to Elyria.
          I'll see whether my grandson & I can remove that panel without ruining it, and unclog it. Worst case: we get an excuse to go to the big box hardware emporium -- which neither of us shirks from doing.
          THANK you all for your help!

            Sorry, didn't catch that my google search found the wrong model.

            I tried searching through the RIDGID Literature Search page but the descriptions are so
            bad for each document you don't know what you're looking at until you download it.

            Some just say 'Operators Manual' with no model number.

            But here's where I was looking if you want to give it a go:

   gallon vac&PageNumber=2

            Also, are you sure the model number you listed is correct? I don't see anything close to
            that many digits in the model number.

            Can you give us a photo of the data plate on the vac?

            Or maybe you can pick it out of a lineup:

              Sorry, BobD, I snuck an 8 between the letters and numbers of the model ID: it's WD16360. (Plate photo attached.) Btw, Ridgid's Literature Search "doesn't recognize" 16360 or WD16360.
              I did get the top plate off without trashing it; it's simply a housing over the compact fan atop the vacuum motor; there's no filter material in there, nothing to clog -- and it was clean as a whistle. I guess my next move will be to open the fan assembly up from the 'bottom' of the housing, see if anything's awry on/in that side of the air channel. Will wait a couple of days, though; my grandson's away, whom I want to continue introducing to the fascination of hacking machinery.
              Thanks again for your solicitude.

                If you look here you'll find you model listed and it shows some parts.
                I see a blower


                There is a copy of the manual here if you don't have it.
                I couldn't find it on RIDGID's site either.

                  Verify the conditions of the brushes.
                  Ace Hardware may have replacement [generic] brushes.

                    The brushes! It figures, Cactus Man; but it's so long since I'd tinkered with electric motors that I'd completely overlooked that. Thank you!
                    Your advice sent me to:
                    Thanks again to everyone here. This is a great site I'll bookmark for life.
