Kenmore 70 series - all churn, no burn
« on: June 14, 2015, 09:35:24 AM »

quick background....recently moved in with my elder parental units.  My brother has lived 10 minutes away for years but really has never done his part.  Now i'm here for the long haul, day in, day out - but when anything mechanical or constructional is needed he swoops in with his toolbox for five or ten minutes, changes a fuse or glues down a loose tile, and is the froggin' hero.  Please assist me in just this once robbing him of his village people construction guy hardhat savior status.  And no, I'm not bitter!!!!

I'm from the IT world where you don't post the same damn thing someone else already did and clog up the forum, but this here typie talkie place seems to be run in the opposite way, as I noted someone being told to start a new thread.

The model and exhibited behavior match this existing thread as best I can tell:  http://appliancejunk.com/forums/index.php?topic=3550.0

We've got a Kenmore 70 series.  DWJR-ELE 2406028-FM54  The drum will turn, the light will burn, but your wet clothes still for heat they yearn.

I have access to one of them fancy testelectrical thingies, but no idea how to use it much.  I can follow directions though, and really wanna tug on superman's cape this time.

Some more random, maybe relevant facts:  Mawmaw sez the medium setting has been known to sort of work when it wants to, whereas the high setting has worked always (now it appears there's no heat at all).  That woman is maniacal about the lint trap, so on my life, it cannot possibly be that, or hell will be yearning for heat.

I'm going to get the panel off now, and see what I can see, and look forward to the empowerment your guidance will afford me!!!!!   :thanks: 8)

  It's not the thermal fuse as that's in the motor circuit, not the heat circuit. Otherwise, in addition to the other testing recommended, make sure you have 240vac at the power cord connection block at back of dryer. If the timer is advancing normally, you can skip that test as the timer motor also runs from the 240vac.  Also test the thermal cutoff and timer terminals BK to R with timer on and dryer unplugged.

Mz3 / Fairbank - Can't thank you enough, except by asking for more information/help.

Testing reveals it to be the thermostat that's bad.  The timer does run correctly, thereby eliminating the first additional test Eric mentioned.

Can you please elaborate on his other suggested step, I'm very much a noob.  Are we talking about where the power cord connects to the machine at this point, or where thermal cutoff attaches?

Also test the thermal cutoff and timer terminals BK to R with timer on and dryer unplugged.


Finally, are the cheapish parts ok, or should I go for OEM parts in this case?

  So, one of the thermostats reads open? Which one? The hi limit or the cycling (operating)? If one is open, then no further testing is required. Don't go cheap on parts, there's a lot of junk out there. Is your model number 11066752500 ?

Yes, the high limit thermostat shows no continuity at room temperature.  Thanks again for the help!

because your high limit is open, you will want to really consider cleaning your venting or replacing it. Make sure the exit of it is not blocked by anything.
