general electric dryer does not start

Dryer does not start. I haven’t used it in 2 weeks because I was on vacation, I unplugged it & plugged it back in. I turn off the trip switch on the electrical panel & turned it back on. I remove all the lint each time I use the dryer. The door is securely closed & I turn it on the way I usually do but the dryer will not start. It's over 7years old but I'm not sure how old it actually is because when I moved here this was already here, do you think this is fixable or should I buy a new dryer? I called GE they told me this electric dryer is either from October 1986 or October 1998. general electric heavy duty automatic dryer
