I have a whirlpool LGR5636EQ0 The furnace will not lite. It's a gas dryer.

I figuered it out. It was the thermal fuse.

This was a while back. All I did was go to the Sears Parts Store, this is different than Sears itself although some sears have a parts store in them. I simply gave them the model number of the drier and they gave me the part. I then spent about 5 minutes on the internet and foud a repair manual. It waws super easy, took maybe 20 minutes. I had to take the back off and it was right inside. Sorry, I don't have the link to the manuel any more. Total includeing getting the part from the store took about an hour and a half and the fuse was lint 10 or 15 dollars.
