William June 16, 2022 Has anyone suspecting the sensor has failed tried simply cleaning the surface of the sensor where it is exposed to the wet laundry? I took mine apart to see what might be wrong and to justify ordering a new pair of sensors. The parts are just formed stainless steel strips and they looked perfect with the exception of a bit of color (blue or blue-green) on the surface. No broken parts, no corrosion. So I cleaned the exposed surfaces with ScotchBrite and reinstalled them. The sensor is now working again. And the next time it fails I will do the same but skip the disassembly step. These can be cleaned without removing them from the dryer. So what is the coating I cleaned off? My best guess is either fabric softener or residue from the anti-static dryer sheets -- or maybe the combination of those two things.
1 Answer Hello William, This is the recommended fix for the issue with one exception. You should clean the sensor bars with a clean cotton cloth and rubbing alcohol. This will not wear down the sensor bars like using an abrasive such as Scotch-Brite. The coating on the sensor bars is actually from softener sheets and will clean off easily with the rubbing alcohol. Read More...
Pete December 22, 2021 for Model Number dle3400w I own an LG Electric Dryer, model DLE3400W. It seems to heat fine, but was giving me "nP" error and occasionally a flow sense error like "d80" or "d90". Power & plug are fine. It has it's own double breaker and has worked well in the current location for many years. Still, "nP" error suggested power issue, so I replace the main control board with a brand new one. I don't get the "nP" error anymore, but after a few loads I'll sometimes get the "d80" or "d90" errors. I've cleaned and completely replaced the ductwork and vacuumed out the inside chamber of the dryer and even wiped down the fan blades. There are no obstructions. I have gotten the "d80" error even when no duct in attached to the back. My question is, given the dryer is clearly NOT clogged with any lint, what sensor is falsely telling me there's a flow sense error? What do I replace next? Thermistor? Sensor bars? I don't get it. Thank you for you help.
1 Answer Pete, based on the information provided, the most likely cause of failure would be the thermistor 6323EL2001B. Read More...
Tony March 29, 2021 for Model Number DLE0332W My dryer starts up in sensor mode and then shuts down with in a few seconds. Sometimes with a filter warning. I tried timed drying and that worked better. I cleaned the Moister sensor bars and they seemed ok. I cleaned the dryer duct from the dryer yo the outside. None of this helped. Sometimes it works perfectly, other times it turns on and shuts down with in a few seconds. This is really making my wife angry. It worked for about tow weeks , no problems. Tonight is started stopping quickly again. this is with my wife using the dryer ( electric). I wet some towels and put them on cotton towels and turned it on. It seems to be working, but I have done this before and it would not run. Looking for that magic list of a few parts that I should order and get at it. Where is the thermister?
1 Answer Hello Tony, the thermistor is mounted to the blower housing and using a multimeter it should read about 12k ohms at room temperature. Read More...
Abel September 11, 2020 for Model Number DLE1501W My dryer works on times dry. When I put it on sensor dry, it doesn't heat as much and the time changes down fast.... I guess the machine thinks clothes are dry? Could this be the moisture sensor? Any other issue it could be? Is there a way to test the moisture sensor? Thank you, Abel
1 Answer Abel, It would be recommended to try and clean the sensor bars with an alcohol pad and see if this does not correct the issue. If this does not correct the issue then check to make sure that the wiring is not damaged and replace the sensor bars. Read More...
Philip February 01, 2020 for Model Number LG DLEX7177RM Changed out all thermostats only needing to change out sensor bars, they show some thin copper wires sticking out of them. Maybe changing these out will get my dryer to heat or will it?
1 Answer Phillip, This issue may not be the sensor bars that would be causing the unit to not heat. There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the Control board. The best option is to disconnect the power to the unit and access the heating element. Disconnect one wire that is going to the heating element, preferably the one on the thermostat side. Plug the unit back up and using a multimeter you will want to turn the dryer on and test for 120 Vac at the terminal on the heater where the wire was disconnected. What this will do is eliminate the heater element itself and the motor. If there is 120 vac at this point then you know the heater is good and the motor is good because the other 120 Vacs coming through the thermostats is the control board side of the circuit. If there is not 120 vac at that point then you will want to test the other terminal on the heater and check for 120 Vac. If there is not 120 vac then the motor would be bad. Read More...
Amateur December 13, 2018 for Model Number DLEX3470W Trying to replace moisture sensor holder as tab got broken off during cleaning. I cannot remove wires from moisture sensor - do not want to force too much in case I break them. Is there some special trick?
1 Answer Amateur, If you grab the connector with a pair of needle nose pliers you should be able to pull the wire connector from the moisture sensor bar. Read More...

Jeff September 19, 2018 for Model Number dlex5101v If the sensor is bad does it prevent the Add Water light from coming on when the water reservoir is empty?
1 Answer Jeff. The moisture sensor being bad would not cause the Add water light to not come on. Read More...
