I have had this dryer now for about 16 months. Clothes do not get dry if I use the sensor dry settings. Even the More Dry setting will still leave the clothes wet. It will dry the clothes if I do a time dry. I have checked the vent hoses, and the all appear fine, including the outside vent. I am thinking that it must be the sensor dry. I was hoping that you could tell me how to check the sensor and see if it is defective.
Thank you!
Ok, Jeff, I see you have a front loader, electric. On this model we have inlet thermistors, outlet thermistors, and the sensor bars are non serviceable, which means they are part of the blower housing. Not a big deal. Let's put it into a test mode and test the voltage drop of the sensors. They are on the inside of the drum just below the vent gate. 2 bars. Unplug the dryer for 30 seconds. Plug it back in and within 10 seconds press in this order: signal button, delay start, signal button again and delay start again. The consol should show t01. This is test 1. You want to turn the main dial clockwise until the test shows t09, this will be the sensor test. With the drum dry it should show around 5 volts DC. Now take a wet rag and place it over the bars, the display should show a voltage drop to around .5 or 1volt DC. If it does this the sensor is working properly. See if you can run this test successfully and post back. Catriver.
Jeff, I got a head of myself, after you turn the dial to t09, press start to enter that test. Then power to exit it after your done. To exit the test mode, do the same key dance in the same order or just unplug the dryer for 30 seconds.
That's not that far out of range, take some emery cloth and go over the bars lightly, see if that makes any difference. Catriver

Hi catriver. The dryer is a GE model # DCVH515EFoww. It does have a digital display.
FYI. We cannot use dryer sheets, or fabric softener in the washer as our daughter does not do well with them. Maybe allergic? I have tried cleaning the sensor rods and that did not make any difference.
Thanks for the reply. I am hopeful that with your help we can determine why it is not working as it used to.
Jeff
catriver,
I was successful in running the test. However the lowest that the voltage would go was to about 1.19 volts. And that was with a rag that was dripping wet. If I wrung out the rag, like the clothes come out of the washer, the voltage would only go to 1.56. It kind of looks like we might be getting closer! What is the next step?
Thanks for your help catriver. I cleaned the sensor rods and the sensor dry now seems to be working better. It still seems to take longer than it used to to dry a load, but all appears to be working well. Your advice on how to check the sensor was very helpful.

J, I really need to know the model number here so I don't lead you astray. The moisture sensing rods are part of a circuit that uses a low voltage capacitor. Ranging from 5VDC when it's open and 1VDC when the circuit is shorted. When wet clothes touch the 2 rods, they create a short which discharges the capacitor. When the clothes become dry, they cant short the circuit and the charge builds to 5VDC. When the control board reads 5VDC, it thinks the clothes are dry . If your model has a digital display, a test can be run from the board. On this example of how this works, the capacitor is in the harness near the sensor rods and can be replaced as a seperate componet. That's why I need the model number. If the dryer is leaning backwards, it will be hard for the load to cross the sensor bars. Also, if there is a build up of fab softner on the bars, it will create a false reading. On this certain model, if the rods are not shorted within the first 6 minutes of the cycle, the cycle will terminate. Post back, Catriver.
