My name is XXXXX XXXXX I am an authorized Whirlpool service tech and I can help you today.
To answer your last question, "replacing the sensor would be the most likely cause of this issue or some other part?", my answer is yes and no.
to clarify, yes the sensor being replaced could cause this issue if you have a bad sensor. Or if you have forgotten to plug the connections in.
and No, this is not the only cause for the the sensor light to stay illuminated. I have seen a clogged dryer vent cause this. So please do this.
first remove the dryer venting in the back of the dryer and let the dryer run without the venting attached. It will be completely fine for you to run the dryer like this for s hort period of time as we check. You can actually run the dryer like this for days. But you may not be happy about the lint and moisture in the air around the dryer. It is just to test the machine.
So disconnect the venting and run the dryer on a timed dry setting and tell me if the sensor light goes off?
If it does, clean your dryer venting out.
If not, then replace the sensor or check the wiring down below to make sure it is connected properly. If it is connected properly replace the sensor and the thermistor on the blower housing next to the thermal fuse. This will fix your problem.
Please get back to me here if you have more questions and I will continue helping you.
ok, let me do what you recommended

Thanks and please run those tests and get back to me here to tell me what you have found.
how long does it typically take for sensing light to change to dry or damp
Just so you have it, the part number for the thermistor is(NNN) NNN-NNNN/p>
It depends on how wet the close are?
I threw about about 4 wet hand towels in there
if they have gone into the dryer really wet, it could take as much as an hour. sometimes will only take about 15 minutes.
for the sensor light to change?
and how long did you give the light to go out? or when you checked the towels, were they dry? and light still on?
yes, that is right, for the light to change to dry.
when I turned it on, the timer said 40 minutes...
if the clothes were dry and the light was still sensing clothes were wet, and the connector below is conncted just fine, i recommend replacing the moisture sensor and the thermistor.
ok. and were the clothes still wet?
I let the timer run down to about 7 minutes and the towels were still damp
light was still on as well
if they were still wet and the sensor light still shows damp and drying, then let it run until the clothes are dry and check it again. if the clothes come out dry and the sensor is still sensing that they are wet, replace the sensor.
ok. gotcha, i am a little behind in getting your responses here. sorry.
I would change the sensor then and the thermistor. cheap parts.
when you say check the wiring down below what wiring am I checking?
so the sensor in the drum and the thermistor
There is a wire connector, even two on some models, for the moisture sensor that is just inside the drum ont he inside of the lint screen. The wire goes from the metal strips on the lint screen to harness belwo the machine.
check the harness just below the lint screen.
the sensor pad moisture sensor is in the back of the machine.
just under the screen where the heater gets blown into the dryer drum.
it is part number(NNN) NNN-NNNN
check the wiring to it in back of the dryer. just infront of the lint screen housing that is metal.
if you dont see any loose or disconnected wires then replace the sensor pad assembly.
and remember to remove the dryer venting as well to be sue the venting is not partially clogged.
did not see any wires hanging or loose connections.
ok. so then replace the moisture sensor pad assembly.
did you see the part number i included above?
so still recommend replace thermistor and sensor?
if not here it is again, the sensor assembly(NNN) NNN-NNNN/p>
yes. for sure replace the thermistor and sensor.
that should do it.
I see this problem often
I used appliance parts pros for the parts, is that the website you recommend using, they shipped fast and part cost seemed reasonable?
and if the wires are good then replace the sensor and thermistor. not one or the other. both have to be replaced at the same time.
let me check pricing there.
i usually use a local place called marcone. they usually have the best price.
ok, I will check it out.
appreciate help, I will replace those two parts and hopefully that will take care of it...I replaced almost everything else
