2 yr old Kenmore Elite Dryer. Sounds like their is a pair of sneakers when I turn on the dryer. With or without clothes in it. And of course it's out of Warranty. It dries and runs but makes a noise.
One trick to make sure the gas is not leaking when you get it all set up is to put dish liquid on the joints with a Q-tip and if it bubbles up there is a leak.
John Deere recommends a 2.5. All the heavy equipment on my job site has them. Get one with a quick release hanger,and mount it on the fuel tank side of your tractor. It's really for accidental fires during fueling and in case of engine fires.
