    Default Stat differential too great

    Model - pdet910awy

    When the differential is way off, and there does not appear to be any difference in the cycling of low heat regular and high heat regular with dryer empty, is this an indication of a faulty operating stat?

    Stat differential too great-cycling-thermostat-wp37001136-00777000-jpg Thermostat, cycling L146-15F

    there does not appear to be any difference in the cycling of low heat regular and high heat
    I found only 1 thermostat and no other temp control on the fan blower housing....how is high or low heat selected on this dryer?....I do not see any way for this dryer to be other than one heat and one heat only.

    Sorry Jeff, wrong model number. Should have been aed4475tq1. This is one among a few I have had with differential problems and seemingly no difference in low and high heat. This one and the others have the operating thermostat with the bias heater (3387134).
    This one had Reg/High and Reg/Low Heat settings on the timer. I suspect the opetating stat bias heater.
    Again sorry about my mistake.

    I should add the differential on some these appear to be around 40-50 degrees instead of the 15-15 or whatever some are rated at. According to my thermometers I use to check them with. They get a little too hot, cut out, then cool down around 110 before kicking back in.

    his one had Reg/High and Reg/Low Heat settings on the timer.
    Have you recorded the heat on and heat off temps in both settings?
    Write them down and post the results here.

    Both seem to be the same around 160 or a little higher cut off. Drop to around 110 then back on.
    I think I made another post similar to this concerning ambient temp.

    Record the actual temps, take readings ( maybe 6 on and offs ) and write them down for both settings. Then we can compare.

    I think maybe the ambient temp is affecting the thermometer reading on the last few since we discussed ambient temp.
    Think I had posted this but accidently deleted it.
    If I run into this problem again when the ambient temp is higher or close to room temp, I will record the cutoffs and ons.
    Appreciate your patience ol' buddy.

    It certainly would.

    Great
