See this page for the 12 Volt 30 Amp relay we use for most kilns.

See this page for the 240 Volt 30 Amp relay we use as a control relay for 480 volt kilns.

This video shows how to change phase on an L&L Easy-Fire kiln. It will similar on most other L&L kilns with power cords.

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.

This video shows how to check a control fuse on an L&L automatic kiln.

How to check to see if a thermocouple is OK.

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

How to check the operation of a control transfomer 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.

How to replace a damaged side brick in an Easy-Fire or other sectional L&L kiln. This video shows replacing both a brick where the element connections are and where the peephole is (the two most difficult bricks).

How to repair cracked brick in a front-loading kiln. First remove the damaged brick using a drill and chisel to route out and remove brick. Then shape a cut firebrick piece to fit in the space and cement in place. Then sand. Let the cement dry overnight and then do a slow bisque firing to cone 5. This same technique can be used on kiln bottoms and in other situations like on the side or back. Hi-Temp kiln cement can be used instead of phosphate bonded cement (which is no longer available).

Some thoughts on repairing brick from Andrew Seymore from Clayscapes with Jessica Putnam-Philips from Clayshare.

This video shows you how to replace a lid on a DaVinci kiln.

This video shows how to repair minor cracks in the bricks on a front-loading Easy-Load kiln. Can also be used in other situations where you do not want to remove firebrick. Hi-Temp kiln cement can be used instead of phosphate bonded cement (which is no longer available).

How to repair hairline crack - typically in tops and bottoms. Hi-Temp kiln cement can be used instead of phosphate bonded cement (which is no longer available).

How to repair a cracked ceramic kiln top or bottom. Tighten the stainless steel band as soon as you cement the pieces together. This acts as a clamp. Hi-Temp kiln cement can be used instead of phosphate bonded cement (which is no longer available).

This video shows you how to replace a lid on an Easy-Fire, School-Master, Jupiter, eQuad-Pro, JH Series kiln with a spring-assisted lid. For 23" and 28" models only.

This shows some interesting techniques for repairing firebrick in front-loading kilns where it is difficult to replace an entire firebrick section.
