I have a Frigidare dryer model # FGQ1442ES0, 9 years old. When you first turn it on, it makes a pulsing scrapping noise, the very second the heat comes on, the noise instantly goes away, it's a gas dryer. If I run it in no heat mode, that noise is there all the time, the moment I turn the heat on, it goes away. I thought about replacing the felt strips and bearing (about $100.00), but thought I would ask to see if it may be something else. Has anyone experienced this problem, that could help me out?
