hello, welcome to just answer. my name is XXXXX XXXXX and i will be happy to assist you with your problem. This is a bad motor. What is happening is the motor has an overload on it and when it gets hot it will shut the dryer down. it will then not start again untill the motor cools down. The more you run the dryer the worse the motor is getting and is why it is stopping earlier and taking longer to start. The motor can be purchased at www.appliancepartspros.com at a discounted price.
what causes that burnt gas smell in gas dryers occassionally?
Im sorry about the delay. For some reason the system is not telling us techs when the customer replies back every time. As for the gas smell this could happen if the vent on the outside of your house is in an area where wind can blow against it, it is possible that you can be getting some slight back pressure from time to time and is why your only getting it every now and again. There is really no other way to get this smell inside the house as all of the fumes are pushed straight out the vent to the outside.
