How do I replace the blower belt on an Avanti dryer?

Sometimes the dryer doesn't come on at all. Sometimes it does, makes a strange noise, and doesn't dry well. I had it looked at by a professional and was told it needs a new blower belt. How do I replace it myself? They want me to pay an amount almost equal to the price of a new dryer for the repair. Thank you. Sometimes the dryer doesn't come on at all.
