This is the moisture sensor for your dryer. It helps detect the amount of moisture in your clothes during the dryer cycle. If you notice your clothes are still wet after an automatic dryer cycle is done, you may need to replace the sensor. You will find the moisture sensor behind the lint screen. Be sure to disconnect the power source from the dryer before you begin this repair. Note: Some model's require two sensors, please order quantity needed. Sensor only, harness is not included. This part is sold individually.

Easy Repair, Not the Problem
The parts (2) fit perfectly. Easy repair. Unfortunately, this was not the problem. However, when I took off the back of the lint screen to replace them I did discover three handfuls of lint trapped inside. So that was something. I also replaced the heating element, which was also not the problem. Finally called a repairman. Dryer needed a high limit thermostat. Works great now.

fixed it with these parts
I got em, put em in and it worked. Though I think the connections to the old simple strips of metal were wet and grounded out, causing the fault. But they got here quick.
Thanks

Good Part, Really Slow Shipping
Part was easy to replace. Although I dont understand why they only come with one when two is needed. It took a good while to arrive. Like three weeks, plus about week for them to to actually ship it. Hope you're in no hurry for your dryer.

Dryer would run 1 min then stop running with some heat in drum
Videos are excellent to open and access internal parts. It turned out a rat was killed in the blower fan when we first encountered the problem. This prevented the blower from turning which interfered with motor function.

After getting rid of the rat and decomposition, we sanitized the entire housing with soap & chlorine bleach.
Reassembly was uneventful and relatively easy. We ended up replacing 4 rollers, 2 belts (drum belt & blower belt), the thermistor which was damaged as a result of the blocked blower.

Timer isnt working right quits to soon
For model number MEDB400VQ1
Hi James,
Thank you for your inquiry. Where the dryer is shutting off too soon, There are some parts that you will need to check to see which one is causing the issue. You will need to check the internal bias thermostat, the sensor electrode, the high limit thermostat, the thermal fuse, and the lint filter. I hope this helps. Thank you and have a great day!

When I try to use the dryer it reads sensing. Is this the what I need. How many 1 or 2.
For model number WGD8200YW0
Hi Freddie,
Thank you for the question. The most likely part that needs to be replaced is the Disposable Thermal Fuse, PartSelect Number PS11741444. Also make sure the ducting to the outside is a full 4inch and there isn't a lot of crimping or turns.
Hope this helps!

My dryer sometimes runs on and on even when cloths are totally dry . Could this be a faulty moisture sensor?
For model number 11067032600
Hello Charlie, Thank you for the question. Yes, the Sensor is the first part we suggest to replace. if this does not fix the issue, it might be the timer. The timer on this model is built into the control board, so the board will need to be replaced. PartSelect Number PS11746555.Hope this helps, good luck with this repair!
For this model do I need to replace one or the two electrode sensor? On the videos I seen they only change the top one. Are they both sensors? If so do I need to replace both of them? Also what's the part number for electrode sensor?
For model number MGDB850YG2
Hi Danny, Thank you for the question. The sensors are sold individually and if both are defective then they will bot need to be replaced.The part number is above, PS11741408 Hope this helps!

When I turn my dryer on the timer is set for 35 min. Within 10 min. The timer will say you have 11 min to go & then dryer stops to early & clothes didn't get to dry for 35 min. Could you tell me why? Thank you, Pam
For model number WED8300SW0
Hi Pam, Thank you for the question. This sounds like an issue with the timer. The timer is built into the control board, PartSelect Number PS11746631 on this model. The board is not repairable so it will need to be replaced. Hope this helps!

I noticed it was taking a much longer time for my clothes to dry. I also noticed when i pushed the button on the front of the machine to select "dryness level", the light was out. My husband thinks the moisture sensor is bad. Would that cause the "dryness level" selection light to not illuminate?
For model number WGD75HEFW0
Hi Lori,
Thank you for your question. If your clothes are taking too long to dry, the moisture sensor is just one of the parts you will need to check. There are some other parts that you will need to check to see which one is causing the issue. You will need to check the coils, the radiant flame sensor, the internal bias thermostat, the igniter and the belt. I hope this helps. Thank you and have a great day!

Hi Danny,
Thank you for your question. If the dryer is getting too hot, there are some parts that you will need to check to see which ones are causing the issue. You will need to check the internal bias thermostat, the electrode sensor and the lint filter. Make sure both the lint filter and the duct are clean. I hope this helps. Thank you and have a great day!

My dryer turns off after a while, senor says check lint filter, I cleaned the trap, taken off grill cleaned down in lint trap also cleaned outside vent also shop vac inside dryer. Thanks
For model number MGDB700BW0
Hi Tim, Thank you for the question. You can try to press and hold Save Energy button for 3 seconds if you have one,that resets it. The "Check lint screen" light is just a reminder to check and clean the lint screen before or after each load. There is no sensor that will detect if it's clean. The Check lint screen should turn off as soon as the dryer is started. You can try to check the wire harness between the console and the electronic control board. The control board might need to be replaced if the light will not go off. Hope this helps!

Lights are on but the unit will not start. I turned it off as during the cycle it seemed hot. Do you have any suggestions?
For model number gew9250pw1
Hello Dan,
The thermal fuse is the most likely reason for both symptoms happening. You may wish to use a multi-meter to test the part for continuity, and replace it if it is not showing continuity.
I hope this helps.
