Dryer works, buzzer sounds continuously when cycle complete

I have a Kenmore dryer that dries clothes as it should; however, at the end of the dry cycle the cycle knob does not move all the way to off. The dryer will stop, but the buzzer will sound until I advance it slightly. Also I noticed that if I open the door mid-cycle the dryer starts immediately. I used to have to push the start button to restart the cycle.

Yes, that will do it. I don’t know why some of those timers do not come with the resister. Tom http://www.applianceeducator.com

As usual could not find a wiring diagram for the !%#@ Kenmore.

So here is a wiring diagram for an unknown Kenmore/Whirlpool

Yours is probably similar but may have more thermostats etc.

Resistor is not used in timed dry. It uses the 120 volts. (TM/WB closed)
In Auto (TM/OR closed) when a thermostat shuts off the heater you actually get the 240 from L2 on the left side of the heater. The timer then is run from the 240 (L1 to L2). The resistor reduces the voltage across the timer to 120 which it requires. The above is not exact but should give you the gist of how it works.

I would disconnect the buzzer and see if the timer will advances to the OFF position. If it does my guess would be that the buzzer needs replacing.

ALL THE ABOVE ASSUMES THAT IT IS AN ELECTRIC DRYER

I will try the resistor. The buzzer is an inconvenience; however, what concerns me is the fact that when I interrupt the cycle by opening the door I can continue the cycle when I close the door. It used to be if I opened the door I would have to close the door and push the start button. Now as I said it is like there is always a signal to start/continue the cycle. Could there be a problem with the start switch? As I think I mentioned, when the timer gets to 0 on the timed setting the dryer DOES shut off, the buzzer goes constantly and if I move the timer dial a cycle starts immediately without pushing the start button.

Have a Sears electric heater, need wiring diagram. Can anyone help? Thanks kd.
