Hi APP - Thank You for responding. In response to your answer, Yes, the door switch is fully functional and operates the circuit correctly. The motor switch also functions properly. The original 303358 drive motor with Gray, Dark Blue and yellow winding leads are powered off the now obsolete 303877 motor switch. In normal operation, as the motor ramps up to 1725 RPM, the centrifugal switch on the motor shaft pulls in which allows the contacts on the motor switch to return to the normally 'un-acted upon' state. Therefore, the power drops off the Gray lead and transfers the top contact to complete the Yellow lead of the drive motor to neutral. The bottom contact completes the heating circuitry from Black lead to the Light Blue and White wires to neutral. As reported in previous post, heating circuitry functions properly, verified with continuity across all components. 125 VAC is present across the motor leads and the thermal device clipped over the motor windings is good. (Thermal in Dark Blue 'Run' power supply to motor.) The motor does not have external 'Start' and 'Run' Capacitors so only conclusion is Gray wire to internal 'Start' windings is not powering the 'Start' function. Not enough 'juice' for the motor to start rotation. Your thoughts? Also, what is the rating of the motor overload device clipped above the windings on the drive motor? Thanks! TM

I have no power when start switch depressed and dryer will not start. Full 125 VAC to dryer. 125V on Red wire to start switch. Power transfers to Yellow wire when switch depressed. Interesting note, I have 125V on both terminals of the buzzer; Black wire on left (125V from power in) and Gray wire on right (125V from off timer block). Dryer operated perfectly until this loss of power. All other components check okay with continuity across the devices. Any ideas?
