Does anyone have any suggestions as to why my dryer dries clothing great, yet the dial does not advance no matter what setting the dryer is on? I start the dryer and walk away for about half an hour and when I come back, the dial has not moved at all…even after the clothing is dry, the dial is still in the same position as when I started the dryer, and the dryer will not shut off. There is no "timed dry" setting on my dryer. It seems the only timed mode on this dryer is "air fluff". Other than that, there are just more dry, less dry, cool down settings, etc. I thought maybe the timer was bad, yet when I turn the dial while the dryer is shut off, I can hear the timer ticking away. So, is the timer bad, or is there something else wrong? I tried looking up an owner’s manual online for the dryer, but cannot find one. I know how to test the timer, but am unable to, as I don’t have the correct tools. Any suggestions?
Hi,
If you set your dryer on the timed dry (air fluff) setting and the timer still does not advance then you have a bad timer.
Hello,
Thanks for your reply. I just tried the dryer on "air fluff" for about 10 mins and the dial did move and the dryer did buzz and shut off when it was supposed to. I thought I had already tried that, but I guess not…now I feel kind of dumb. 
Anyway, I then set the dryer to "Auto-dry Regular" on less dry, and now I’m just waiting to see if the dial moves at all. So far the load has been drying for about 10 mins and the dial has not moved, so at this point I’m not sure if it will or not; it may be too soon to tell, but we’ll see…
I could not find a wiring diagram for this unit so the following is not unit specific.
Usually in Auto modes the timer gets power only when the heater cycles off.
If your heater is not turning off the timer will not advance.
A common cause for a heater not turning off is a grounded element. The heating coil touching the case.
If you can set and feel different temperatures on the unit this is probably not the cause.
Some timers are 240 volts so run directly off the heater voltage.
Other timers are 120 volts and they use a resistor in series with the timer motor to drop the heater voltage to 120. It is not uncommon for this resistor to burn out.
I looked at the parts breakdown on this site and could not find a separate resistor.
But I did notice a white device on the timer perhaps this is the resistor.
Usually it is around 4000 to 5000 ohms.
I just read something online about some Maytag dryers that are designed so that, when they are set to "auto-dry", the dial will not advance until the clothes are almost dry, then it advances near the end of the cycle. Do you by chance know if this would apply to my dryer, LDE7500 ?
