    Default same part number, different rating

    Why is it two thermostats have the same part number but different heat ratings?

    Case in pomint is 131298300 operating stat. One is rated at like 140-10 one is 135- whatever. I assume that little difference is actually a good bit?

    P.S. Went back and checked the ratings, and I can see where there would be a good difference overall. The latter gets down to 120 before coming back on. The latter only gets to 130 and kicks back on.

    Still do not get the different numbers.

    Probably a different part vendor....one might have gone out of bizz so they bought different ones from another......could be a product update as the 140?F is a little higher heat than the 135?F version.

    I guess that makes sense. The local parts house sometimes have parts with the same number priced a little differently. I assumed these parts were supplied by different vendors.

    I noticed the different heat settings when I looked for the stat for a dryer that sometimes does not dry as it should. It seemed to take a while to reach the top rated temp when it would quickly kick off. I changed the fronts thinking maybe the front felt was worn. Thought that solved the problem, but evidently, it did not. Or, my daughter is putting too big of a load in it. Now I am thinking of trying the higher rated stat.

    It does have a moisture sensor in the duct at the front. I do not see how this works as the leads are connected to each ...bar terminal, but there is no connection between the two bar terminals.

    Anyway, back to the drawing board.

    Hope all are having a good Christmas.

    I think this is the part I was referring to. Looks like it. I changed the front of the dryer because the felt looked weak. I had to install this since the front I replaced it with did not have the moisture sensor on it. Same front except for that.

    Yes and no. The front I used did not have the sensor bars to start with. I swapped that part of the duct so it would have the sensor bars. I brought the dryer to my shop from my daughter's house. It seems to work fine on timed cycle. I feel the problem at her house was the flex venting. This is the second time I have replaced dryers there in about 2 months. Both which work fine here in my shop.

    I sold the first one I took out of here house. No problems from it.
    I dried clothes in this one yesterday in the cool shop with no problem.
    I cut some of the flex tube off so it would be a straighter run to the vent which is really close to the dryer.

    I was just confused as to how the sensor worked. The two bars make contact/close the circuit when there is moisture in the drum?

    The wet clothes short accross the bars when the clothes contact them....this is recorded by an electronic board. As the clothes become dry(er) they no longer short accross the bars from the lack of moisture and the board picks up on this telling the control to start towards the off position.
