Samsung Dryer stopped heating

Model Number: DV365ETBGWR/A3
Brand: Samsung
Age: 1-5 years

The dryer stopped heating. I replaced the Thermostor, thermostat and the heating element. After replacing the heating element and the thermostat it heated for about 30 minutes. Now the screen shows the cooling light always on and no more heat. When it did start heating the side of the dryer got very hot. I am not sure if that is normal or not.

Thanks,
Scott

The following site has a service manual.

Unplug the unit and both wires from the heating element.
Check across the heating element, most are in the 8 to 12 ohm range.
Then check from each side of the element to it's case, both should be infinite ohms. If not the element is grounded and should be replaced.

Also check the safety thermostats, all should be 0 ohms.

There is a possibility that the control board is toast. Perhaps a bad element took it out or it just went bad on it's own.
