I have a 2yr new Maytag dryer, and everytime the electronics kick-on to ignite the pilot - there is a single, loud "TICK" or "CLICK" (choose your flavor) heard throughout the GAS LINE in the ceiling rafters. We are on a slab foundation, and the gas line runs the entire length of the house (from dryer, to water heater, to stove, to meter - in that order).
Now, I'm not talking about the little 'tick' you would normally hear when the pilot ignites - But like I said, a LOUD "TICK" :eek: - like someone tapping on the pipe with a butt end of a crescent wrench. And this happens throughout the entire cycle, everytime the pilot ignites...
We just moved to this house last year and brought the dryer with us - and all was fine at the other house..? and all other appliances in line work fine and do not entice the pipe into chiming up as the clothes dryer does... So...?
