I suggest when you go to get a new dryer that you have hubby work on the vent system and make sure it's very very cleaned out. My mom's was completely clogged and her dryer finally would not even turn on for more than a moment. The safety switch would not allow the gas to ignite.
My old dryer just wore out, it was from 1972 so it obviously was a piece of junk too...lol. It worked for such a long time once we put a new air system on the back of it. The one that was fully clogged went through the roof out of the garage. It had lots of room for packing stuff to gather. Over a foot of it was a clog.
I got an electric dryer this last time and I am amazed!!!!!!!!!!!
I have always used gas and I washed heavy jeans the first load out. I popped them in the dryer and put it on high expecting to come back an hour later and them still be damp. 20 minutes later the dryer is off. I yelled at my hubby that something was wrong with this new dryer. The washer was not even done with the next load. The jeans were completely dry....go figure. I had been using gas my whole life and them taking at least an hour for even the lightest load of perma press or dedicates.
I won't ever go back to a gas dryer unless I have no choice.
