Could a failing Thermal Fuse cause the WHIRLPOOL WED4815EW to have symptom: Won T Start?

The thermal fuse is a critical safety component located on the blower housing. It is designed to fail open if the exhaust temperature exceeds a specific threshold, usually due to a restricted vent. Once the internal solder link melts, it creates a permanent break in the electrical circuit to the drive motor, rendering the unit unresponsive.

Could a failing Dryer Door Switch cause the WHIRLPOOL WED4815EW to have symptom: Won T Start?

This component acts as a physical logic gate for the appliance. If the internal mechanical spring fails or the copper contacts corrode, the switch cannot signal to the timer that the door is securely closed. Because the motor circuit is wired in series with this switch, a failure here prevents any electrical current from reaching the motor.

Could a failing Drive Motor cause the WHIRLPOOL WED4815EW to have symptom: Won T Start?

The motor uses a centrifugal switch to transition between start and run windings. If the windings have suffered an insulation breakdown or if the centrifugal mechanism is jammed with lint, the motor cannot generate the magnetic field required for rotation. This leads to a failure to start, often accompanied by no sound or a faint hum.
