Move the dryer to access the rear panel where the power cord enters.

Remove the lower panel screw with a quarter inch hex head driver and open the panel.

Look for any signs of damage or burnt wiring on the terminal block or cord.

Use a multimeter set to AC voltage to confirm 120 volts on each leg to neutral and about 208 to 240 volts across both hot legs.

Reset the breaker by turning it off, then cycling on, if voltage is incorrect, or replace the cord or consult an electrician if the outlet is faulty.
