Glow coil won't stay lit

Hi my name is Erik. My dryer isn't working rite I took off the panel and looked at it while it was on this is what's happening. Once I turn it on the glow coil turns orange and than you can see a flame that will last for about 15 seconds than it is off for like a minute than it turns back on for the same amount of time than off it continues this pattern and my cloths at the end of the cycle are wet. Is this a small problem that can be fixed or is the dryer junk?
