no error, but do not heat, no dry, only fresh air.
Generally when the dryer will run but not heat the problem is in the electrical components or the heating element.
First check to see the 120v is coming to each side of the connection block. The disconnect the dryer and test the thermostat and thermal limiter for continuity. Finally test the heating element for resistance and make sure it is not broken or grounded.
Good luck, let us know what you find out.
