Evenheat · Electrical Parts · Thermocouples Evenheat Type-K Thermocouples Eight types · Type-K · Gauge and length specific The thermocouple is how the controller knows the temperature, and it drifts as it ages — usually reading low, which means your kiln over-fires without ever showing an error. If your cones are suddenly going flatter than the controller claims, this is the first part to suspect. Order by gauge and length, not by price. A thicker gauge lasts longer but has to physically fit the port and the insulators your kiln uses.

Common questions
How do I know mine has failed?A dead thermocouple throws an error. A worn one does something more dangerous — it reads low, so the controller keeps pushing and the kiln over-fires while the display looks normal. If your witness cones are going further than the program says, suspect the thermocouple before you blame the elements.
Which gauge should I pick?The one your kiln was built with. A thicker gauge does last longer, but it has to fit the port and the insulators, and the controller was calibrated around a specific part. If you want to change gauge, ask us first.
How often should it be replaced?There is no honest hour figure — it depends on how hot and how often you fire. A heavily used studio kiln might want one every year or two; a hobby kiln can go far longer. Firing witness cones occasionally is the cheapest way to catch drift early.
Kiln over-firing or throwing an error? Tell us the model, the controller type and what the display shows. We will help you work out whether it is the thermocouple before you buy one.
