Removal of old lint collector and replace with new one.

PartSelect showed seven different possibilities why the dryer wouldn't heat. I removed the two screws to remove the bottom panel and turned the dryer on and noticed that the heating element that ignites the gas was working fine. This meant that it was not getting gas so it could be the gas valve or one of the two gas valve coils which are ... Read more located on top of the gas valve. I borrowed my neighbor"s ohm meter and touched the two probes on the coils terminals to check for continuity and found that one of the coils read zero. I then took both of the coils out by removing two screws and tested each coil again. One coil read 500-850 and the other read zero. This meant that it was no good so I called for the part and received it in three days. I reassembled the parts and turned the dryer on and it fired up after a few seconds. It works as good as new. The part plus shipping was less than $30. My repairman would have charged me $150-$200. While the dryer was apart I gave it a good cleaning with a vacuum and a toothbrush in delicate areas. I also removed and cleaned the lint trap housing by removing two nuts. I didn't know much about gas dryers, but thanks to PartSelect I easily fixed it myself.
