Turn the dryer and check continuity between M1-M2 of the motor. If continuity found, replace motor. If not, start the dryer and check for continuity between M1-M2 of the motor, if not present replace the motor. Check for shorting of the heating element to ground/chassis, if shorted, replace heating element. If no heater shorting found, check impedance across the heating element. If found open, replace heater. If found okay, check continuity of Thermal Limiter-2. If found open, replace. If found okay, check wiring (harness connectors for Heater Relay-NO, COM; Thermal Limiter-2 connectors; Motor Connectors: M1 and M2; Heating Element Connectors). If all found okay, replace control board and retry.
