Auto dryer not auto!!!!!!

[Medic130]

I have an Amana electric dryer and a problem with the auto setting. The timer seting works fine, but the auto cycle doesn't dry the clothes. I have replaced the moisture circuit board and the thermostat that cycles between heat and timer. I have completely cleaned the duct work and it still doesn't work right. I have used my ohm meter and found that the timer is getting juice constantly which I find odd since I replaced the thermostat that gives it juice. I also metered the thermostat that was replaced and my ohm meter needle just kept vibrating and jumping untill the meter "got fryed". It didn't ever blow the fuse, just fryed. The heating element is getting juice and seems to work fine. I tested the moisture bars inside the drum and on top where the wires enter the moisture circuit and the meter didn't move at either place. I assume that is good. It is as if the auto cycle just runs through its time and quits. I am stuck now so any help is good. I am now assuming the timer is bad but every where says that that rarely happens. Maybe I am one of those rarelies.

Thanks in advance,
Marty

Your washer may not be spinning the clothes dry enough for the dryer to do its job - Don't overlook this possibility

I know it is not my washer, but thanks for the help. If someone who knows more about electricity than I could help, I would greatly appreciate it.

Marty.
Suggest changing the timer. Based on the parts you already replaced and tested, timer likely bad. Internal contacts may be burned out in that cycle setting. At this stage of repair replacing that timer sounds likely to be the cause and worth a try.

Good Luck.

What kind of clothes? Do they not dry at all, or are they just damp?
Have you metered the temperatrure of the exhaust at the dryer while it cycles? If so what kind of range are you getting? How long does it take for a heat no heat cycle? Do the clothes dry completely and to your satisfaction during a timed cycle? What are the temperatures and times like on a timed cycle? Is there an appreciable temperature difference between cotton sturdy, delicate, and permanent press?
SO, talk to me.

I have not metered the temperature at the exhaust. Clothes dry fine on a timed cycle. I have just replaced the timer but it still doesn't work right. I will meter the temps, but what should I be looking for? My wife is getting angry, because I can't get it fixed. I have too much money wrapped up to call a repair man now.

A $4 stick thermometer will save you a world of guessing. Without knowing what the temperature cycles are you don't really know where to start.
Probably there is a stepchart inside the dryer cabinet. You can look at that and test the timer (probably the timer breaks neutral, that's why there's power every where).
Could be very well be the timer is at fault, given you have replaced as much as you have; and it works on the other side of the timer.
So let us know which way you decide to go
