The dryer moisture sensor is an architecture to detect the particular moisture level in the dryer. It can adjust the dry cycle time in aggression mode, and the dryer moisture sensor is one of the prime concerns of the dryer machine. This is the most crucial element of the dryer. If the moisture sensor is defective, then the dryer will be in a spinning mode associated with the wheels.

Where is the dryer moisture sensor located?
If the dryer moisture sensor feels agony, you must locate and repair that sensor. If the sensor does not operate properly, you must face intermittent detection in the dryer itself. For finding this senor, you need to give the basic knowledge about the progression process of the dyer. You need to check inside the dryer drum where two metal strips are facing fast-forward, long and side-by-side deployments. This sensor could be on the back portion of the plastic housing that tightly attaches to the lint filter. You can also find the memory casing on the back wall of the dryer drum. If you fail to locate this particular sensor, then the main thing you can do is check the manual of the dryer for further manipulation. In some cases, this sensor is situated at the closer rear wall of the dryer. 
The working mechanism of the dryer moisture sensor:
You will be mesmerized to read the working mechanism of the dryer moisture sensor. It is not like the typical sensor. Rather just sneaks the irregularities in the system. It has more extensive things to do. As we have mentioned before, the moisture sensor in the dryer consists of two robust metal bars. A black plate gives them support for further processing. The metal bars are associated with the dryer’s drum, and When they come closer, it formulates the closed short circuit.
An extensive electrical impulsing Rolex controls the total amount of moisture in the device. If this sensor fails by any chance, then the device fails to detect moisture and automatically turns off. Too much dirt, lint, and rust on the dryer sheets may be the biggest reason for collapsing the whole thing. It is crucial to clean the unit’s moisture sensor as everything depends on this system. The metering display dashboard shows all the stats related to the continuity and replacement of the sensor. Finally, you need to check the continuity of the flame sensor.
The control panel of the dryer has a close bond with the thermistor. It is capable of regulating the drum’s air temperature. The resistance of the elements sometimes fluctuates and horrifies the optimum temperature. Too much high temperature or excessively low temperature is not good for the control panel. The heater automatically shuts off if the sensor sneaks that the clothes are dried perfectly. If the thermistor indicates that it requires more air temperature inside the dryer drum, then the internal sensor manages that change in a proper fixation.
Why does the dryer moisture sensor stop working?
You may have faced the most vehement discrepancies created by the dryer moisture sensor. There are thousands of reasons why the moisture dryer sensor fails to reconnect with the other parts of the device. Here I will try to cover all those aspects simply but effectively. The two metal strips, which are the lifeblood of this device, stop proper functioning. The Dryer sheets coat must be outworn as time advances. The moisture sensor may stop working as the inherent insoluble metal strips fail to operate. A film coated with waxing makes it easy and effortless to sense moisture in the external compartment.
How to examine the dryer moisture sensor with a multimeter?
A multimeter is a fantastic device that can evaluate multiple sets of electrical voltage and the flow of current. A smart digital multimeter can measure the current’s continuity and duty cycle, as well as the dryer moisture sensor. A digital multimeter can read and test the condition of the moisture sensor dryer decently and conclusively.
A thermostat is a tremendous supporting element that is found in electric dryer models. A high-limit thermostat is related to the thermal fuse box. If the cycling thermostat is dead, then it takes more time for the dryer to dry the clothes. The thermal fuse initiates the entire program. If it gets blown out, then you need a multimeter to test the defective part measured with the electrical continuity. A well-calibrated multimeter can rotate the speed dialing with the perfect amalgamation of resistance Ohms. The component’s terminals show zero Ohms of resistance if the fuse or moisture sensor gets burned.
Let us have a look into the complete testing process of the dryer moisture sensor with a multimeter.
Clean the metal strips:
At the very beginning, you need to clean the two metal strips. Wipe these with the alcohol solution so that the metal gets the glossy effect and can prevent unwanted oscillations. Then you need to rub the two metal strips decently. You can use a small wire brush for polishing the metal strips. Then use 400-grit sandpaper for rubbing and giving it the final touch. 
Check the moisture sensor:
In the second stage, you need to set the dryer to Auto Drying mode. Try some clothes to see if the moisture sensor is working properly or not. Take a piece of cloth and let it soak in the foamy solution. Then assign the moist piece of cloth to the dryer machine. Reset the dryer in Auto Dry setting mode. After about half an hour, turn off the dryer. It must be automatically turned off after the process is finished. If the dryer is still operating, then repeat the testing process several times.
Check the automatic cycle:
Testing the moisture sensor is very much crucial for the dryer. Then check the settings on the dryer and also have a reminder of the automatic drying cycle. If the dryer can not be acquainted with the automatic cycle, you need to inspect the timed dry setting. The moisture sensor must assign the controlling process to engage the automated drying period. Ensure that the dryer is set to the automatic cycle. Otherwise, the multimeter cannot read the live data. 
Check the resistance and voltage:
After performing all these steps, assign the multimeter to the driver’s seat. Uncover the backward portion where all the system checks and circuits are located. Imply the multimeter to check the resistance and voltage of the particular segment. Check the moisture sensor with the help of a multimeter. Impose the different terminals with the assigned wires and take the sensor’s reading with the digital multimeter. If the dryer resumes drying the clothes after stopping the main socket, then there is something wrong with the moisture sensor. Everything is alright if you see that the dryer turns off automatically. You might have fixed the problem with the multimeter. If you feel that something is suspicious, then test the power to the moisture sensor again. We shall approach the further steps.
Get the data:
After locating the moisture sensor, you must get a reading above 0, or the onslaught goes higher. The inception of the reading that is nearly 0 or exactly 0 might indicate an imperfect moisture sensor. The sensor might be dead, so you need to replace the sensor as soon as possible. That might be costlier so take a fruitful preparation according to the situation. Replacing the sensor will make the dryer as efficient as a new one.
Check the fuse box:
There must be a diagram inside the fuse box lid. Test the fuse box and apply the multimeter at the further process. Check each terminal with the multimeter to see if the reading matches the standard value as depicted in the owner’s manual. Take note that the dryer will show its precision for about five minutes at the random stage before it shuts off. The heating element that has contact with the terminals should be checked properly. At the last stage of testing, inspect the rated value of the device at the manual forum.
Set the multimeter to ohms as it is the standard unit test lead. After you inspect the circuits and sensors with the multimeter, take the necessary steps to resolve the issues. If you cannot solve the problem, then take the help of a professional mechanic, as a defective dryer moisture sensor can destroy the entire device within a few days.
