The clock motor in an Intermatic T104 timer will occasionally fail. It is time to replace the mechanism if the yellow wheel stops turning but the manual switch still functions correctly. The following steps will provide a guide on how to replace the WG1573-10D.
The Intermatic WG1573-10D clock motor should now be successfully installed if the yellow clock dial is turning. Close the timer door and continue to enjoy the energy savings of using a timer.
