Hi I have a Amana ned7200tw dryer.My wife informed me it is taking to long to dry a load of clothes.The first thing I checked was the vent.I checked it from the vent screen to the discharge and all was free of lint.then I checked voltage and that was 240.So then I cycled the dryer on manual temp. thinking that mybe the dry sensor mybe faulty.What I did observe that the heating coil would come on for about 17 seconds and off for about 2 minutes almost like it was on a delicate cycle.There are no error codes.Could this be a thermistor,thermostat,or fuse problem?Thankyou

If the element is fine then you have a sensor problem. there are only a few of them. Best just to replace them all. They usually all come in one pack anyway.

Just a question. Does your blower work. If your blower does not work it won't dry. Check blower belt. Mine broke and had no air blowing. Just a thought.
Did you check the trap door on the outside of the house where the vent goes outside. If the door is stuck or the end of the vent is blocked you will get excessive dry time like you are having. Also possibly a thermostat inside starting to go bad and sticking.
try looking at the moisture sensor strips. usually inside the under the door area. two strips that sense moisture as the clothes roll by. these may be broke, shorted or need replaced?
you will need to clean the vent tube/internal duct work:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature then the thermostat tells the
timer to begin advancing. The
timer advances until the interior cools, then the thermostat tells the
timer to stop advancing, and tells the dryer to start heating again.
if the vent/duct work is clogged then 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.
I hope this helps here is a website on how to remove cabinet:
The spark ignitor maybe at fault. Listen for the clicking noise upon starting it up the first 30 seconds it runs. If not heard it is in need of a replacement
Very common problem. You need to call a duct cleaning company and tell them to clean your dryer vent. Rule-of-thumb: dryer vents should be cleaned every couple of years to prevent them from being clogged with lint and causing lint fires. This is definitely your problem. Good luck :)
p.s. one way to verify a clogged vent is to go outside where the vent exits the house and feel the air-flow. should have adequate air-flow.
