Error Codes for the One-Touch Control

tC FAIL tC alternating with FAIL

Indicates the thermocouple has failed. Replace the defective thermocouple. To clear the error, press any key.
Errd Displayed whenever the kiln temperature is 100°F (38°C) above the traveling set-point, which is the current desired temperature in the kiln. The traveling set-point will increase or decrease according to the programmed rate.

Err1

Displayed whenever the kiln temperature is rising during an up ramp slower than 15°F/hr. (9°C/hr) If this rate continues for 8 minutes the firing will be stopped. Err1 may be an indication that the elements are worn or that a relay has stopped working.

ErrP

Displayed whenever there is a power interruption that is long enough to stop the firing. If the power interruption is brief, the kiln will continue to fire when power is restored; in this case, there will be no indication of a power failure. To clear the error, press any key.

ErrF

Displayed whenever the kiln temperature is decreasing during a down ramp slower than 15°F/hr (9°C/hr). If this rate continues for 8 minutes the firing will be stopped. ErrF may be an indication that a relay has stuck in the on position.

tC--

The red and yellow thermocouple wires are reversed
