Kiln Repair & Maintenance

Element replacement, thermocouple and controller diagnosis, and firing-uniformity tune-ups for the kilns we sell and the ones you already own.

Why It Matters

A kiln is a machine, and machines drift

A kiln is a machine that runs at temperatures hot enough to melt rock, and like any machine it drifts and wears. Elements lose their punch, thermocouples read low, relays stick, and one day a load comes out underfired for no reason you can see. Most online retailers cannot help you with that. We can, because we service kilns as a core part of what we do.

We diagnose and repair Skutt, L&L, AMACO, Olympic, and Paragon kilns, and we are happy to look at other brands. Element replacement, thermocouple swaps, relay and controller work, brick repair, and full firing-uniformity tune-ups using witness cones top to bottom. For schools and studios on a firing schedule, regular maintenance keeps a kiln out of the failure that always seems to happen the week before a deadline.

What We Service

From a stuck relay to a full tune-up

We service Skutt, L&L, AMACO, Olympic, and Paragon, and we are glad to look at other brands.

Element replacement

When elements lose their punch, firings slow and ware underfires. We replace worn elements and restore your kiln to its rated performance.

Thermocouple & controller

A drifting thermocouple reads the wrong temperature and ruins loads quietly. We test, calibrate, and replace thermocouples, and diagnose digital controllers.

Relay & wiring

Sticking relays and failing connections cause uneven heating and intermittent faults. We track them down and repair the electrical path.

Brick & lid repair

Cracked firebrick and worn lids waste energy and threaten uniformity. We patch and restore the kiln's structure.

Firing-uniformity tune-up

Using witness cones top, middle, and bottom, we map your kiln's real heatwork and correct what is making it fire unevenly.

Preventive maintenance

For schools and production studios, scheduled service keeps a kiln out of the failure that always seems to land the week before a deadline.

Keep Firing

Do not wait for the load that fails

If your results have drifted, your cones are telling a different story than your controller, or your kiln just is not reaching temperature, bring it to us before it costs you a kiln load of work.
