My dryer will not heat. The "drying" light blinks while its on regardless of the setting and the cooling light stays on the whole time. I had a repairman out and he changed the heat sensor. It worked for about 6 loads, then quit heating again. The second repairman said it was the other sensor and changed it out, but also said that the venting system through the house was too long and had too many bends in it. He recommended that we vent it straight into the garage before using it again. We did that and it worked for about 3 loads, then stopped heating again. The lights continue to stay as previously described both times it was "fixed" and heating. The power button also doesn't always turn it on. It some times takes a few pushes to get it to come on. Any ideas? I am really tired of paying $100 service call fees to have someone not fix my dryer!

Heather for Model Number dle5977w

ANSWER Hello Heather, You may want to check the thermistor to see if it is faulty. You check the thermistor by unplugging unit and disconnect the 6 pin connector at the thermistor. Thermistor is located on the blower housing. Measure between terminals 3 and 6 and you should read 9.7 ohms at 80 degrees and 11.7 at 70 degrees. If thermistor is not reading proper ohms replace the thermistor 6323EL2001B. Also check blower wheel to ensure it does not have heavy lint build up on it causing issue. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
