A dryer moisture sensor can stop working without notice, until you notice your clothes being over dried or still wet at the end of the cycle. It is a good practice to test the dryer moisture sensor periodically. There are two types of moisture-detecting sensors for dryers. Once you understand how they work you will see how to test each one.
1. Sensor BarThese sensors contain digits that protrude outwardly. They work on an electrical current and the moisture from the clothing.
The first step to test is to place completely dry clothes in the dryer and turn on the dryer; it should run for a few moments and then shut down right away.
Secondly, place damp clothes into the dryer, turn on the dryer and watch the timer. As the clothes begin to dry the timer will move and shut off.
2. ThermostatThe timer is regulated by the thermostat. The thermostat rests in a closed position. To test this type of moisture sensor, place damp clothes in the dryer. Watch the timer; as the clothes begin to dry, the thermostat should open and the timer will move forward ,eventually shutting off.

Hello, Thank You for using FixYa. I will be helping you today.Replace the timer.It has a bad contact.
Thank You and please rate my answer if it was helpful..

Clogged Vent
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.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

Hello there:
A lot of the times the problem lies with in the Cycling thermostat that is going out Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly.and can make the dryer stop working after it is working for a given amount of time If so, you need to replace it.
Next is the The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws. It overheats and shuts down due to a bad thermostate Usually when an electric dryer overheats it's because of a defective cycling thermostat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above).

First turn off both breakers then back on. Next, check the wiring from the receptacle to the plug to the back of the dryer. Next, the thermal switch under the top of the dryer next to or near the drum may be bad. Bypass it and see if you get heat. If so, then replace it for about $20. Your heating element may be bad also. You can visually check it and see if it is burned in 2. Now your timer is probably bad. They are easy to replace and fairly inexpensive.
I guess after looking at all this, you need to decide if it is all worth it to fix it. If it is more than 10-12 years old, you may be seeing the beginning of the end. If the thermal switch, the element, the timer are all bad, you may want to make room at the curve and take the door off for safety. Dryers aren't that expensive especially when you consider the hassle. Good luck and let me know how and what you do.

The coin operator timer consists of several small plastic gears. The teeth on the last plastic gear gets all chewed up so that the timer continues to run and unable to open the circuit which stops the dryer timer. Although the plastic gear probably costs pennies, your will need to order part number 33001275 torsion timer for about $75 - $110. Remove one screw & 3 clip-on wires - 15 min.

the dryer wont stop running only when open door will it start a fire?
