Sometimes when my wife is doing laundry the gas clothes dryer will start making a loud noise. This doesn't happen right away, but after sometime. It doesn't do it every load, but once it starts doing it doesn't stop unless she stops the machine and waits a while. It seems to be a vibrating type noise
I checked the the exhaust duct and there isn't any buildup. But it keeps taking longer and longer to dry.
Thanks in advance for the help.
