The primary difference between the two configurations is how the Neutral and Ground wires are terminated at the terminal block. In a 3-wire configuration, these two wires are terminated together via a grounding strap. In a 4-wire configuration these two wires are independent of each other and should NOT be terminated together.
If you have any questions about this repair, please let me know. I hope this helps you.

My GU 120 stops mid cycle and the indicator light starts blinking a humming whirring sound preceeds the ctcle stop nad light blinking. Pressing the button for 5 seconds causes the flashing light to extinguish but the sound continues untill the unit stops. It does not complete the full cycle. Your help would be appreciated. Tony
