How to check to see if a thermocouple is OK.

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

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.

See this page for the standard type K thermocouple.

See this page for the mounting hardware.

This video shows how to remove a control panel on an Easy-Fire, School-Master or eQuadPro kiln for service.

In this video we will demonstrate how to upgrade your kiln from Type K thermocouples to Type S.

• Brick plugs
• Brick cement
• Type S Thermocouples (short for most kilns)
• Type S Thermocouples (long for Easy-Load)
• Type S Lead Wire (by the foot)
• All Type S Lead Wire (Assemblies)
• Spade Terminals for thermocouples
• Checking a Control Fuse on an L&L Automatic Kiln (Video)

How to check the operation of a control transformer on an L&L automatic kiln. Applies to all automatic kilns that are not 480 volts. The control transformer reduces the incoming line voltage from 240, 208 or 220 volts to 24 volts for the control and 12 volts for the relays. See this page for more detail.

The most important debugging tool in any toolbox is a trusty multimeter. A multimeter can measure continuity, resistance, voltage and sometimes even current, capacitance, temperature, etc.

This video shows how to check voltage on an L&L automatic kiln.

In this video we demonstrate how to replace Type K thermocouples. These thermocouples degrade over time, and we recommend replacing them whenever you replace your elements.
