Sounds like you have a timer switch problem if the timer is not advancing.
The noisy operation sounds like a drum roller problem.
If you have a front loading machine:
Unplug the power cord, remove the front of the machine, this will expose the drum and belt, remove the drum and belt and this will expose the drum rollers.
Check the rollers for flat spots on them, if they are flat spots on them they need to be replaced. If there are no flat spots on the rollers then you may get by with just lubrication on the shafts of the rollers. Use a good grade of machine oil on the shafts of the rollers such as 3 in one Oil.
I hope this helps.

If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.

Normally, this is what happens during an automatic cycle:

  • The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.

  • When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)

  • The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

Amana dryer not advancing on auto


Make sure the vent from the dryer to the outside is clean.
Reduced air flow can cause your symptom.

You can remove the vent hose from the dryer and operate the dryer in the automatic cycle.'
If the timer advances you know the vent needs cleaning.
Clean the lint filter housing also.
A flashlight helps to see all the way down the housing.

Intermittently Drying Problems, Electrical?


It could possibly be electrical, check for 240V at the supply side. The only other possibility could be plugged dryer venting, although it would be unusual for it to cause only intermittent problems. The reason the timer would stop turning (mechanical timer) or counting down (digital display), is because on any Auto-dry, (ones that use the moisture sensor) the dryness of the clothing dictates when the timer should count down or advance. Check for good airflow from the outside exhaust point, if that's ok, I would be possibly looking at the outlet for possible loose contact, look at the dryer cord prongs and see if there are dark marks on them, as this may point to a sloppy outlet causing arcing.

Dryer has to be run repeatedly to complete one load. shuts off before clothes are dry. is this a sensor issue, and how is it replaced?

Won't heat, won't advance on auto, won't shut off on timed. air only fine


I suspect you have a timer motor problem. My experience has been in most cases you cannot buy just the timer moter, you need to purchase the entire timer....at costly expense. If you can get your ear near the timer while running, first listen to hear the motor. Usually when the motor is going to quit, it becomes fairly noisy. In any case, the timer should advance,

Dryer not heating or turning off


It can be multiple problems. First are you using it on sensor dry or timed dry? If it is timed try, it's possible your timer is not advancing. If you are using sensor dry it could be your sensor.

To test the timer, check for continuity across the timer. If it is open, replace the timer.

To test sensor, run the dryer on sensor with nothing in it, if the timer advances quickly, the sensor is not the issue. If it does not advnace, it could be the sensor.

The no heat issue; check to make sure you don't have a blockage in the venting or in the dryer. If there is no blockage, check your element. To check if the element is not heating up, check for continuity through the sensor.

Hope that helps.
