Did you test the sensor bars? Make sure it's clean.
Make sure the vent going outside is clear as well.
I'd also check the blower housing and blower wheel for lint build up.

Yes cleaned out inside.Not hook up to the vent.I will check sensor bars.The dryer will  go down on time to 1 minute and never shut off.Now should it work normal on timed dry?

Try it on timed dry and see if you have and see if your operating t-stat is functional. Also check and make sure that the heater is not grounded to the out side of the heater housing.

One other thing is run it on air fluff/no heat cycle. If it starts to heat definitely have a grounded element to heater housing. Let me know what happens but I have had one that would hold heat and element was grounded to housing. Hope this helps.

I change heater for a new one still the same.Do think one jump wires on the heater could be shorted out.

I replaced the control board now working as it should.
