    Default Estate dryer no advance in auto

    Model: tedx640pq1
    Replaced the operating stat with a new Whirlpool Certified wp3387134
    Timer does not advance in Auto.
    Ran 5 pairs of jeans for almost an hour. Timer never moved. Put in Timed cycle low heat. Timer advanced. Put back on Auto and timer did not advance.
    What am I missing?
    Something to do with the orsnge wire on element?
    Found the wiring diagram. Every thing checked good on the timer. Decided to check the timer motor even. Showd 10.?? K ohms. High?
    Am confused since it does advance in timed cycle.

    G'day,

    That is the correct operating thermostat.

    Ran 5 pairs of jeans for almost an hour. Timer never moved.
    What was the exhaust temp?
    Did the heat go on and off at all? If yes, where where the temps?

    Put in Timed cycle low heat. Timer advanced.
    Good, means the timer motor is ok.

    Put back on Auto and timer did not advance.
    Heat cycling on and off on the safety thermostat and not the operating thermostat. Poor air flow. Air seal leaking air. Grounded heating element. *Some* loads will run 60 minutes before the clothes are dry enough to allow the timer to start to advance on the auto cycle.

    Decided to check the timer motor even. Showd 10.?? K ohms.
    That is good.

    Must not have let it fun quite long enough for it to cycle with a load in it.
    Another thing that may have some effect on it is I have been using and extention cord to check dryers sometimes. I thought the wire I was using was 10 gauge. Turns out all this time I have been using number 12 underground wire. Could that cause this?
    I removed the extention cord and plugged directly into what I think is 8 gauge that had been used for a stove plug at one time.
    I have been using the 12 gauge for quite a while with no know problems that I am sure of.
    Then again, that may be the reason I have had a few problems with dryers lately.

    I doubt it.

    You are probably correct, I also have seen some loads run 45-60 minutes before the timer started to advance towards the off position.
