This video is useful for changing a thermocouple on any L&L kiln - in particular an eQuad-Pro or a School-Master Kiln.

Be sure to maintain proper polarity.

In the USA: Yellow Wire = PLUS (+) Red Wire = MINUS (-) The thermocouples are marked with a (+) and (-). Also the negative (-) is marked with a red marker. The negative wire is MORE magnetic than the positive wire.

For more information about thermocouple polarity, color coding, and markings see this page.
